Answers & Explanations 66-80
66. C: Aligning the decimals at the decimal point and adhering to the same integer addition computation properties, the sum is equal to 109.41539.
67. C: Any number divided by 1 is equal to itself, thus 0.12 ÷ 1 = 0.12.
68. B: By first performing the computations within the parentheses, the expression may be rewritten as 3 × 2, which equals 6.
69. D: The product is 0, since the product of any number, or numbers, and 0, equals 0.
70. B: The division may be performed by first dividing 1.5 into 7.9 and then dividing 1.5 into 0.45. Doing so gives a quotient of 5.3
71 A: Addition of 7 to the integer, -32, shows a movement of 7 units to the right, giving a sum of -25.
71. B: The sum of the two negative integers will be negative. Starting at -37 on a number line and moving 47 units to the left, gives a sum of -84.
72. B: The percentage, 41%, may be converted to a decimal by moving the decimal point two places to the left. In other words, 41 is divided by 100 (or multiplied by 1/100), since one percent represents one-hundredth.
73. C: The word "difference" signifies a subtraction problem. When subtracting decimals, align the decimals vertically. The result is 3.229, Choice C.
74. D: Look at the digit in the thousandths place. In this case it is a 7. Since the number is 5 or greater, round up the digit in the hundredths place. The correct answer is 2.57, Choice D.
75. D: Division is the opposite, or the reciprocal, of multiplication. If you divide a number by 2, you have to multiply it by 1/2 to get the same result.
76. D: When a number is raised to a power, it is multiplied by itself as many times as the power indicates. For example,23=2*2*2=8. A number raised to the power of 0 is always equal to 1, so 60 is the smallest number shown. Similarly, for the other numbers:9=9;101=10;42=4*4=16.
77 D: Substitute the given values for the variables into the expression:
4a (3b+5) + 2b = 4 * -6 (3 * 7 + 5) + 2 * 7
Using order of operations, compute the expression in the parentheses first.
Remember that you must first multiply 3 by 7and then add 5 in order to follow order of operations:
= 4 * -6(21 + 5) + 2 * 7 Next, add the values in the parentheses.
= 4 * -6(26) + 2 * 7 Simplify by multiplying the numbers outside the parenthesis.
= -24(26) + 14 Multiply -24 by 26.
= -624 +14 Add.
= -610
78. D: To find the total amount that will be consumed, multiply the number of glasses consumed by one person (8) by the number of people indicated in the question (18): 8 x 18 = 144.
79. D: To calculate her new weight, add her weight increases (12 pounds and 6 pounds) to her original weight (145 pounds): 145 pounds + 12 pounds + 6 pounds = 163 pounds.
80. A: Use the FOIL method (first, outside, inside, and last) to get rid of the parentheses:
(2x - 20) (5x + 10) = 2x(5x) + 2x(10) - 20(5x) - 20(10) = 10x2 + 20x - 100x - 200.
Then, combine like terms to simplify the expression:
10x2 - 80x - 200.
