Math HESI A2 Practice Test

Correct Answer: D

Rationale: To find 75% of 80, you multiply 80 by 0.75 (which represents 75%). 80 * 0.75 = 60. Therefore, the correct answer is D: 60. Choice A (35) is incorrect because it is not 75% of 80. Choice B (45) is also incorrect as it is not the correct calculation for 75% of 80. Choice C (70) is incorrect as well since it does not represent 75% of 80.

Correct Answer: A

Rationale: To find the result of subtracting 4.7 from 9.5, we need to subtract 4.7 from 9.5. This can be calculated as 9.5 - 4.7 = 4.8. Therefore, the correct answer is A. Choice B (4.9) is incorrect because it is not the result of the subtraction operation provided in the question. Choice C (4.6) is incorrect because it is the result of subtracting 5.1 from 9.7, not 4.7 from 9.5. Choice D (4.7) is incorrect because it is the number being subtracted and not the final result of the subtraction.

Correct Answer: D

Rationale: To find 50% of 120, you multiply 120 by 0.50 (which represents 50%). So, 120 x 0.50 = 60. Therefore, the correct answer is D. Choice A (50) is incorrect because it represents the percentage value, not the result of the calculation. Choice B (50) is a duplicate of Choice A. Choice C (70) is incorrect as it is not the result of finding 50% of 120.

Correct Answer: A

Rationale: The correct answer is A: 50%. A six-sided die has 3 even numbers (2, 4, 6) out of a total of 6 possible outcomes (1, 2, 3, 4, 5, 6). To calculate the probability of rolling an even number, we divide the number of favorable outcomes (3) by the total number of outcomes (6), resulting in 3/6 = 0.5 or 50%. Explanation of other choices: B: 16.70% - Incorrect. This percentage does not represent the probability of rolling an even number on a six-sided die. C: 25% - Incorrect. This represents the probability of rolling any number divisible by 5 on a six-sided die, not just even numbers. D: 33.30% - Incorrect. This percentage does not reflect the probability of rolling an even number on a six-sided die.

Correct Answer: A

Rationale: To find the distance traveled, we first calculate the time elapsed from 1:45 PM to 3:15 PM, which is 1.5 hours. Next, we multiply the speed of 65 mph by the time of 1.5 hours to get the distance traveled, which equals 97.5 miles. Therefore, the correct answer is A: 97.5 miles. Choice B (100 miles) is incorrect because the calculation does not result in 100 miles. Choice C (95 miles) is incorrect as it is less than the correct distance. Choice D (105 miles) is incorrect as it is greater than the correct distance calculated.
