1. Which of the following is the correct decimal placement for the product of 1.6 * 0.93?
- A. 14.88
- B. 0.1488
- C. 1.488
- D. 0.001488
Correct answer: C
Rationale: To find the product of 1.6 * 0.93, you multiply these two numbers to get 1.488. Therefore, the correct decimal placement for the product is 1.488. Choice A, 14.88, is incorrect as it incorrectly places the decimal two spots to the right. Choice B, 0.1488, is incorrect as it incorrectly places the decimal one spot to the right. Choice D, 0.001488, is incorrect as it incorrectly places the decimal three spots to the right.
2. Which of the following is the decimal form of 87.5%?
- A. 875
- B. 8,750
- C. 0.875
- D. 8.75
Correct answer: C
Rationale: To convert a percentage to a decimal, you move the decimal point two places to the left. Therefore, 87.5% as a decimal is 0.875. Choice A (875) is incorrect as it represents the percentage without converting to a decimal. Choice B (8,750) is incorrect as it represents the percentage in whole numbers without decimal conversion. Choice D (8.75) is incorrect as it represents 875% instead of 87.5%.
3. What is the approximate metric equivalent of 7 inches?
- A. 3.2 cm
- B. 2.8 cm
- C. 15.4 cm
- D. 17.8 cm
Correct answer: D
Rationale: The correct answer is D: 17.8 cm. To convert inches to centimeters, you can use the conversion factor 1 inch = 2.54 cm. Therefore, 7 inches is equal to 7 * 2.54 = 17.78 cm, which rounds to 17.8 cm. Choices A, B, and C are incorrect because they do not correspond to the correct conversion of 7 inches to centimeters.
4. In a study of the average weight of babies at different time intervals after birth, the babies’ measured weight is which of the following variables?
- A. Independent
- B. Control
- C. Dependent
- D. Constant
Correct answer: C
Rationale: The baby's measured weight is the dependent variable as it depends on the time intervals.
5. A consumer recently purchased a new car and paid $48,000. This amount is $2,000 less than twice what the consumer’s friend paid for their car. Which of the following is the amount that the friend paid for their car?
- A. $23,000
- B. $46,000
- C. $25,000
- D. $50,000
Correct answer: C
Rationale: To find the amount the friend paid, you can set up the equation 2x - 2000 = 48000, where x represents the amount the friend paid. Solving this equation gives x = $25,000. Therefore, the friend paid $25,000. Choice A ($23,000) is incorrect because it does not account for the $2,000 difference mentioned in the question. Choice B ($46,000) is incorrect because it is double the amount needed. Choice D ($50,000) is incorrect as it does not consider the $2,000 less mentioned in the question.
