question
Long ago, the mice had a general council to consider what measures they could take to outwit their common enemy, the Cat. Some said this, and some said that; but at last a young mouse got up and said he had a proposal to make, which he thought would meet the case. "You will all agree," said he, "that our chief danger consists in the sly and treacherous manner in which the enemy approaches us. Now, if we could receive some signal of her approach, we could easily escape from her. I venture, therefore, to propose that a small bell be procured, and attached by a ribbon round the neck of the Cat. By this means we should always know when she was about, and could easily retire while she was in the neighborhood." This proposal met with general applause, until an old mouse got up and said: "That is all very well, but who is to bell the Cat?" The mice looked at one another and nobody spoke.

question
As Arctic ice continues to melt, the polar bear's quest for food often leads to swimming long distances, ultimately ending in starvation. Last year, a policy paper outlined a multi-step plan to save the ever-declining polar bear population, which included the risky suggestion to feed the bears directly.

question
Passage 1 While Alexander Graham Bell was experimenting with telegraph instruments in the early 1870s, he realized it might be possible to transmit the human voice over a wire using electricity. Bell's interest in electricity continued, and he attempted to send several telegraph messages over a single wire at one time. It was on June 2, 1875, while Bell was at one end of the line and his assistant Watson worked on the reeds of the telegraph in another room that he heard the sound of a plucked reed coming to him over the wire. Passage 2 After many failed attempts, Alexander Graham Bell invented a working telephone. The next step was to make the telephone accessible so people could use it. This involved putting in lines to carry the telephone messages. The first telephone lines went from one person's phone to another. Those were called landlines. Then they added what are called switching stations, so one line could reach more than one place. Even though it was not the most efficient system, it still worked well enough for people to communicate. Which of the following excerpts most strongly supports the claim that Alexander Graham Bell's early diligence resulted in the telephone we know today? A. "... he realized it might be possible to transmit the human voice over a wire using electricity." B. "... he heard the sound of a plucked reed coming to him over the wire." C.

question
If I could have the best job in the world, it would be to play for a major league baseball team when I'm older. I believe that a major league team should hire me because of my excellent skills. I also have a positive attitude and I want to play the game. Also I think a team should hire me because of the talent I have that will support the team's success. The team could probably win the World Series! They should hire me because I can hit the ball really hard and score runs in every game. I can catch the ball really good. I can get the players on the other team out really easily. I can throw great to all the bases to get them out. I can run the bases OK and when it comes to stealing the bases most of the time I don't get out. My batting average is good. I hardly ever make errors. When I hit the ball, I mostly get singles but sometimes doubles. I might hit a homerun sometimes. I want this job because I'm really good at the sport.

1/1 1/2 1/3 1/4 Which of the following is demonstrated by the figure shown? A. When the numerator stays the same and the denominator increases, the fraction increases. B. When the numerator stays the same and the denominator increases, the fraction decreases. C. When the denominator stays the same and the numerator increases, the fraction increases. D. When the denominator stays the same and the numerator increases, the fraction decreases.
answer
B. When the numerator stays the same and the denominator increases, the fraction decreases. The question requires an understanding of fractions and how to use geometrical representations to compare fractions. All of the fractions shown are unit fractions; that is, fractions in which the numerator is 1. The models accompanying each of the four given fractions are called tape models. In a tape model, the length of the tape represents one whole. This whole can then be divided into pieces of equal lengths, and the length of each piece represents a unit fraction. The way in which the models are organized and displayed shows that the length that represents the fractional part of the whole becomes shorter as the whole is subdivided into more parts of equal length. This is a pictorial representation that demonstrates that if the numerator of a set of fractions is fixed and does not change, the size of the number represented by the fractions will decrease as the denominators are increased.

question
If the geometric sequence below continues to increase in the same way, what is the next number in the sequence? 2, 6, 18, 54, 162, ... A. 243 B. 324 C. 486 D. 729
answer
C. 486 The question requires an understanding of patterns and the ability to find and use a pattern rule. A geometric sequence is a sequence for which the ratio between consecutive terms is constant. The generic rule for a geometric sequence can be written as an=a1(r) to the n−1 power, for n≥1, where a1is the initial term and r is the ratio. In this case the initial term is 2 and the ratio is 3, so the sequence rule can be expressed as an=2(3) to the n−1 power, for n≥1. Another way of representing the same sequence is a1=2 and an=3a to the n−1 power, for n≥2. The next number in the sequence is then a6=3a5=3×162=486.

Because of the real-world context, the solution must belong to the set of all rational positive numbers; therefore, the solution is acceptable. B. Because of the real-world context, the solution must belong to the set of all rational positive numbers; therefore, the solution is not acceptable. C. Because of the real-world context, the solution must belong to the set of all natural numbers; therefore, the solution is acceptable. D. Because of the real-world context, the solution must belong to the set of all natural numbers; therefore, the solution is not acceptable.
answer
D. Because of the real-world context, the solution must belong to the set of all natural numbers; therefore, the solution is not acceptable. The question requires an understanding of how to evaluate the reasonableness of a solution to a contextual word problem. The solution to the given word problem must belong to the set of all natural numbers because the unit is pieces of clothing, which is a positive and discrete unit. According to the word problem, Sara bought 6 shirts, 3 pairs of pants, and 1 1/2 sweaters, totaling 10 1/2 pieces of clothing. The solution is, therefore, not acceptable since it is not a natural number.
question
Mr. Smythe has asked his students to come up with function rules for the following table of data. x y −1 1 0 0 Adam says that the function rule is y=−x, Belinda says that the function rule is y=−x2, and Chandra says that the function rule is y=−x2−2x. Which of the three equations could be the function rule for the table? A. Adam's only B. Adam's and Chandra's only C. Belinda's and Chandra's only D. Adam's, Belinda's, and Chandra's
answer
B. Adam's and Chandra's only The question requires an understanding of the concept of function and its definition. A function is a rule that establishes a relationship between two quantities: the input and the output. To find out whether or not Adam's function could be the rule for the given table, it is necessary to substitute each pair of values, (0,0) and (−1,1), into y=−x to verify whether or not the substitution gives the correct output. This process must be repeated for both Belinda's function and for Chandra's function. It is easy to see that (0,0) satisfies all three rules. Since 1=−(−1), the pair (−1,1) satisfies Adam's function rule. Since 1=−(−1) squared−2(−1)=−1+2=1, the pair (−1,1) also satisfies Chandra's function rule. The pair (−1,1) does not satisfy Belinda's rule, since 1≠−(−1) squared=−1.
question
The community pool has a capacity of 50,000 gallons. It is leaking at a rate of 450 gallons per day. The equation g=50,000⎯450d can be used to find the number of gallons g remaining in the pool after d days. Which of the following statements is true? A. g is the dependent variable because the volume is dependent on the number of days d. B. g is the independent variable because it is what needs to be found. C. d is the dependent variable because it is being multiplied by the independent rate of 450. D. Dependent and independent variables cannot be determined in this situation because the equation is linear.
answer
A. g is the dependent variable because the volume is dependent on the number of days d. The question requires an understanding of dependent and independent variables within various formulas. The input of a function is referred to as the independent variable because the input can be any number. In this instance, the output, referred to as the dependent variable, is the number of gallons g remaining in the pool, because the volume depends on the input variable d, or the number of days since the pool started to leak.
question
Tom's company has to ship 1,944 boxes of shoes. If a truck can hold 450 boxes, how many trucks does he need to ship all the boxes?
answer
5 The question requires an understanding of rounding strategies for reasonableness of results. The word problem can be solved by performing the division 1,944÷450, which yields 4.32. Since the result represents the number of trucks needed, the result must be rounded to an integer. Rounding down to 4 would yield the wrong answer since 4×450=1,800, so Tom would be able to ship up to 1,800 boxes of shoes with 4 trucks. Rounding up to 5 would yield the right answer since 5×450=2,250. Since with 5 trucks Tom would be able to ship up to 2,250 boxes of shoes, he would also be able to ship 1,944.

question
Kyle's father set up a savings account for him with an initial balance of $100. Since then, Kyle has been depositing $28 into the account each week. Kyle represents the amount of money he has saved after x weeks by the expression 28x+100. Which of the following is equivalent to Kyle's expression? A. 4(7x+25) B. 7(4x+100) C. 7(4x+25) D. 4(7x+100)
answer
A. 4(7x+25) The question requires an understanding of algebraic expressions and the ability to manipulate them. Since both 28 and 100 are divisible by 4,4 is a factor of the expression 28x+100. To arrive at the equivalent expression given in (A), the distributive property was applied to 28x+100. In fact, 28x+100=4×7x+4×25=4(7x+25).
question
Which of the following numbers is least? A. 0.103 B. 0.1041 C. 0.1005 D. 0.11
answer
C. 0.1005 The question requires an understanding of place value. To compare the four numbers in the options, the digits that determine place value must be compared moving left to right beginning with the digit in the tenths place. The digit 1 is in the tenths place of each number, so the digit in the hundredths place of each number must be compared. The digit 1 in the hundredths place of the number in (D) is greater than the digit 0 in the hundredths place of each of the numbers in (A), (B), and (C), so the number in (D) is the greatest. In the thousandths place, the number in (C) has a digit of 0, while the numbers in (A) and (B) have digits of 3 and 4, respectively. The number in (C) is thus less than the numbers in (A) and (B), making the number in (C) the least of the four numbers. Another way to approach this kind of problem is to add a zero to the end of 0.103 in (A) and two zeros to the end of 0.11 in (D) so that all four choices represent a value in ten-thousandths. This does not change the numbers' values, but makes it easier to determine that (D) is the greatest, being equal to 1,100 ten-thousandths, and (C) is the least, being equal to 1,105 ten-thousandths.
question
In a certain year, 5 percent of the 2,800 employees of a company had a perfect attendance record. Which of the following computations can be used to determine the number of employees with a perfect attendance record? A. 1/40×2,800 B. 1/20×2,800 C. 1/5×2,800 D. 5×2,800
answer
B. 1/20×2,800 The question requires an understanding of fractions, percentages, and decimals and the ability to recognize equivalence among them. Since 5 percent means 5 one-hundredths, 5 percent is equivalent to 0.05, or 5 divided by 100, 5/100, which simplifies to 1/20. To find 5 percent of 2,800 employees, it is necessary to multiply 2,800 by either 0.05 or 1/20.
question
In the formula d=r×t, if d equals 60 and t remains constant, which of the following is equivalent to r ? A. 60t B. 60/t C. t/60 D. d/60t
answer
B. 60/t The question requires an understanding of simple formulas and the ability to work with them. If d is equal to 60, d can be replaced with 60 in the equation, which will result in 60=r×t. The question asks for determining which option is equivalent to r, so it is necessary to solve the equation for r. Since r is multiplied by t, both sides of the equation must be divided by t to isolate r. The result is 60/t=r.
question
15(4+3)=15×4+15×3 The equation shown demonstrates which of the following? A. The distributive property of multiplication over addition B. The commutative property of multiplication C. The associative property of multiplication D. The additive inverse and additive identity properties
answer
A. The distributive property of multiplication over addition The question requires an understanding of the basic properties of real numbers. The distributive property of multiplication over addition states that for any real numbers a,b, and c, a(b+c) is equal to ab+ac. In other words, adding the numbers within the parentheses and then multiplying by the number outside the parentheses yields the same result as multiplying each term within the parentheses by the number outside the parentheses and then adding the two products together.
question
Which of the following is the product of two even numbers and an odd number, each of which is greater than 1 ? A. 15 B. 16 C. 20 D. 21
answer
C. 20 The question requires an understanding of factors of natural numbers. The question requires a determination of the number that has two even factors and one odd factor. The even numbers need not be unique. In (C), 20=2×2×5; 20 can be written as the product of 2, 2, and 5, so 20 can be written as the product of two even numbers and one odd number. In (A), 15=3×5, and in (D), 21=3×7; 15 and 21 do not have any even factors. In (B), 16=2×2×2×2; 16 does not have any odd factors.
question
In a certain contest, a total of $12,000 was divided among the first-, second-, and third-place winners in the ratio of 3 to 2 to 1, respectively. How much money did the first-place winner of the contest receive? A. $9,000 B. $8,000 C. $6,000 D. $4,000
answer
C. $6,000 The question requires an understanding of ratios. Since the ratio is 3 to 2 to 1, the prize money of $12,000 was divided into (3+2+1), or 6, equal shares. Each of the shares was worth 1/6 of the total of $12,000, or $2,000. The third-place winner received one share, for a total of $2,000. The second-place winner received two shares, for a total of $4,000. The first-place winner received three shares, for a total of $6,000. The solution can be checked by adding the three prize amounts; that is, 2,000+4,000+6,000, and seeing that the total is $12,000.
question
Step 1: Select a numerical value for the variable k. Step 2: Add 3 to k. Step 3: Multiply the result by 8. Step 4: Cube the result. Step 5: End. Executing the algorithm shown is equivalent to evaluating which of the following algebraic expressions? A. (8k+3) cubed B. 8(k+3) cubed C. 8 cubed (k+3) D. 8 cubed (k+3) cubed
answer
D. 8 cubed (k+3) cubed The question requires an understanding of algorithms and their algebraic representations. The expression can be found by following the instructions in each of the steps given. The key steps in the algorithm are steps 3 and 4. When multiplying the binomial k+3 obtained in step 2, it is necessary to multiply both terms. The result of step 3 is, therefore, 8(k+3). When raising a product to the power of 3, it is necessary to raise each factor in the product to the power of 3. The factors are 8 and (k+3). The result of step 4 is, therefore, 8 cubed (k+3) cubed.
question
2, 3, a3, a4, a5, ... The first two terms of the sequence shown are 2 and 3. Each subsequent term, beginning with the third, is found by adding the two preceding terms and multiplying the sum by −2. What is the value of a5, the fifth term of the sequence? A. −14 B. −12 C. −10 D. −8
answer
D. −8 The question requires an understanding of following a rule to continue a sequence of numbers. The first term is 2, the second term is 3, and the third term is found by adding 2 and 3 and multiplying the result by −2. So the third term is −10. The fourth term is found by adding 3 and −10 and multiplying the sum by −2. The fourth term is, therefore, −7 times −2, or 14. The fifth term is found by adding −10 and 14 and multiplying the sum by −2. The fifth term is, therefore, 4 times −2, or −8.
question
x f(x) 100 60 24 45 18 30 12 Some values of the linear function f are given in the table shown. What is the value of f(100) ? A. 30 B. 36 C. 40 D. 48
answer
C. 40 The question requires an understanding of finding patterns in data. Since (18−12)/(45−30)=6/15=2/5, the value of f(x) increases by 2 units for every 5-unit increase in the value of x. The value of x increases by 40 units from 60 to 100, so the value of f(x) must increase by 16 units between f(60) and f(100). Since f(60)=24, f(100)=24+16=40.
question
Wai tossed a fair coin 9 times with an outcome of H H T T T T H H H, where H means heads and T means tails. What is the probability that the next toss will be T ? A. 0.2 B. 0.4 C. 0.5 D. 1.0
answer
C. 0.5 This question requires an understanding of basic probability. If a coin is fair, the probability of tossing heads is the same as the probability of tossing tails. There are only two possible outcomes, so the probability of tossing tails is 1/2. The number 1/2 can also be written as 0.5. Please note that since each toss of the coin is an independent event, which means that the previous results do not affect the current toss of the coin, each time the coin is tossed, the probabilities of H or T would always be the same, 0.5.
question
The population of a certain city was 50,000 people. One year later, the population of the same city grew to 50,600. What was the percent increase in the city's population in that one-year period? A. 0.6% B. 1.2% C. 6% D. 12%
answer
B. 1.2% The question requires an understanding of computing percent increase. The increase in the population of the city is 50,600−50,000=600 people. The value of the fraction 600/50,000 gives the percent increase based on the population before the increase occurred. The fraction is equivalent to the decimal 0.012, which is equivalent to 1.2 percent.
question
Which of the following is an example of the associative property of multiplication? A. ab+c=ba+c B. ab+c=c+ab C. (ab)c=a(bc) D. a(b+c)=ab+ac

C. (ab)c=a(bc) The question requires an understanding of algebraic properties. The associative property of multiplication concerns the order in which the multiplications are performed when three or more numbers are multiplied, which can be changed by inserting or removing grouping symbols such as parentheses. If the same factors are present, and in the same order, but the grouping symbols dictate that the order in which the multiplications are performed has changed, then the associative property of multiplication has been applied. In ab+c=ba+c, ab+c=c+ab, and a(b+c)=ab+bc, there are only products with two factors in each, so the associative property of multiplication cannot be applied. In (ab)c=a(bc), the parentheses dictate that on the left side, a and b are multiplied first, and then the result is multiplied by c, and that on the right side, b and c are multiplied first, and then a is multiplied by this result. The fact that the end results on each side are equal is guaranteed by the associative property of multiplication.

question
At a yard sale, Tenille sold drinking glasses for $2.00 each and plates for $3.50 each. Nicholas spent a total of $18.00 on drinking glasses and plates at Tenille's yard sale. If Nicholas bought at least one glass and one plate, how many drinking glasses did he buy? A. 1 B. 2 C. 3 D. 4
answer
B. 2 The question requires an understanding of equations and the ability to translate a word problem into an equation. If x represents the number of glasses and y represents the number of plates that Nicholas bought, then 2x+3.5y=18. Both x and y must be integers. Therefore, 18−2x must be a multiple of 3.5. The possible multiples of 3.5 for this problem are 3.5, 7, 10.5, 14, and 17.5. The only multiple of 3.5 that is equivalent to 18−2x as an integer is 14. Thus, x=2.
question
The Clearbrook Wildcats basketball team scored an average of 77 points in four games. In the first three games, the team scored 70, 76, and 82 points. How many points did they score in their last game? A. 70 B. 76 C. 77 D. 80
answer
D. 80 The question requires an understanding of average (or arithmetic mean) and the ability to set up and solve several computations. An average of 77 points in four games means that they scored a total of 77 times 4, or 308 points. Since the scores for the first three games are given as 70, 76, and 82 points, it is necessary to add these up (228 points) and subtract from the four-game total of 308 points. This leaves 80 points for the last game's score.
question

answer
D. 500 The question requires an understanding of calculating areas using standard, real-world miles on a map. Area is a two-dimensional representation of a surface (length times width, base times height, etc.). A 1-inch by 1-inch square on Greg's map represents a square 30 miles on each side. The area of this square is 30 miles multiplied by 30 miles, or 900 square miles. On Lori's map, the 1-inch by 1-inch square represents a square 20 miles on each side. The area of this square is 20 miles multiplied by 20 miles, or 400 square miles. The difference between these is 500 square miles.
