Vision a box... Side box 5cm bottom right long side 4 cm front bottom short side 3cm The volume of this box is A. 12 cm 3 B. 15 cm 3 C. 20 cm 3 D. 60 cm3 The correct answer is (D) 60 cm3. The volume of a cubic rectangle is length x width x height: 3 x 4 x 5 = 60 If n is a positive integer divisible by 7, and if n < 70, what is the greatest possible value of n? A. 49 B. 56 C. 63 D. 69 The correct answer is (C) 63. If you know one multiple of a number, you can find the other multiples by adding and subtracting that number. The number 70 is divisible by 7. The greatest multiple that is less than 70 will be 70 − 7 = 63. Blair's average (arithmetic mean) on two physics tests is 7. What should Blair's score be on the next test to have an overall average of 8 for all the tests? A. 7 B. 8 C. 9 D. 10 The correct answer is (D) 10. The arithmetic mean is defined as the sum of the terms divided by the number of terms. 7 = sum / 2 14 = sum Adding the next test's score will change the average to an 8, and the total terms to 3. 8 = (14 + new score) / 3 24 = 14 + new score 10 = new score (4x + 2) (x + 1) = A. 5x + 3 B. 4x2 + 6x + 2 C. 4x + 2x + 2 D. 4x2 + 2 The correct answer is (B) 4x2 + 6x + 2 . This is a multiplying binomials problem. Multiply the first term in the first binomial by both terms in the second binomial: 4x2 + 4x Then multiply the second term in the first binomial by each term in the second binomial: 2x + 2 Adding them all together you get: 4x2 + 4x + 2x + 2 4x2 + 6x + 2 2 − 8 ÷ (24 ÷ 2) = A. -6 B. -¾ C. 1 D. 2 The correct answer is (C) 1. Remember your order of operations: Complete operations within parentheses first. Calculate exponents. Then multiply and divide in order from left to right. Then add and subtract in order from left to right. 2 − 8 ÷ (24 ÷ 2) = 2 − 8 ÷ (16 ÷ 2) = 2 − 8 ÷ 8 = 2 − 1 = 1 3(x − 4) = 18, what is the value of x? A. 3/2 B. 22/3 C. 6 D. 10 The correct answer is (D) 10. Begin by dividing both sides by 3 to open the parenthesis: x − 4 = 6 Add 4 to both sides to find x: x = 10 A scoutmaster is preparing his troop for their annual fishing expedition. He surveys each of his scouts to find out how many fishing poles they own. fishing pole owned What is the mode of this data set? A. 0 B. 1 C. 2 D. 3 The correct answer is (A) 0. The mode of the data is the number that appears the most often. In this case the largest number of scouts (7) own 0 fishing poles. Line l passes through the point (−1, 2). Which of the following CANNOT be the equation of line l? A. y = 1 − x B. y = x + 1 C .x = −1 D. y = x + 3 The correct answer is (B) y = x + 1. The slope-intercept form of a line is y = mx + b. Since the line passes through (−1,2), there are three possibilities: the line will have a slope (the "m" in front of the "x" variable), it will be vertical (x = −1), or it will be horizontal (y = 2). Plug x = −1 into all four equations to see which equation is not satisfied. The only answer choice that doesn't give us y = 2 is (B). If 511 = 52 x 5m, what is the value of m? A. 3 B. 5.5 C. 9 D. 12.5 The correct answer is (C) 9. When multiplying two powers with the same base, you can always add the exponents. This means that 11 = 2 + m, so m = 9. Which of these expressions is equivalent to: 3x3y5 + 3x5y3 − (4x5y3 − 3x3y5) A. -x5y3 B. 6x5y3 − x3y5 C. 7x5y3 D. 6x3y5 − x5y3 The correct answer is (D) 6x3y5 − x5y3. The key to this problem is distributing the negative sign. When distributing a negative sign, each term has a change of sign from negative to positive or from positive to negative. 3x3y5 + 3x5y3 − (4x5y3 − 3x3y5) 3x3y5 + 3x5y3 − 4x5y3 + 3x3y5 6x3y5 − x5y3 A rectangle is cut in half to create two squares that each have an area of 25. What is the perimeter of the original rectangle? A. 20 B. 25 C. 30 D. 35 Question 11 Explanation: The correct answer is (C) 30. The formula to find the area of a square is side x side. If each square has an area of 25, then the dimensions of the rectangle are 5 x 10. The perimeter is the sum of all the sides, and would therefore be 5 + 10 + 5 + 10 = 30.
