HESI A2 Math Practice Test 2024

Correct Answer: B

Rationale: The military time 15:17:52 is equivalent to 3:17:52 PM in regular time. To convert from military time to regular time, we subtract 12 from the hour if it is greater than 12 to get the PM time. Therefore, 15 - 12 = 3, indicating it's in the afternoon. The correct answer is B (3:17 PM). Choice A (2:17 PM) is incorrect because 15 is greater than 12, so it would be in the afternoon. Choice C (5:17 AM) is incorrect because 15 is in the afternoon, not morning. Choice D (9:17 AM) is incorrect because 15 is in the afternoon, not morning.

Correct Answer: A

Rationale: To find how much the student earned for working 6 hours, we can use the formula: Earnings = (Total pay / Total hours) x Hours worked. In this case, Earnings = ($120 / 10 hours) x 6 hours = $72. Therefore, the correct answer is A: $72. Choice B, $90, is incorrect as it does not match the calculated amount. Choice C, $80, is also incorrect. Choice D, $50, is incorrect because it is too low based on the calculated earnings for 6 hours.

Correct Answer: A

Rationale: To solve 5 1/3 + 3 1/2, first convert mixed numbers to improper fractions: 5 1/3 = 16/3 and 3 1/2 = 7/2. Then, add the fractions: 16/3 + 7/2 = (32+21)/6 = 53/6. Convert the result back to a mixed number: 53/6 = 8 5/6, which is choice A. Choices B, C, and D are incorrect as they do not represent the correct sum of the given mixed numbers.

Correct Answer: B

Rationale: The military time 15:17:52 is equivalent to 3:17:52 PM in regular time. To convert from military time to regular time, we subtract 12 from the hour if it is greater than 12 to get the PM time. Therefore, 15 - 12 = 3, indicating it's in the afternoon. The correct answer is B (3:17 PM). Choice A (2:17 PM) is incorrect because 15 is greater than 12, so it would be in the afternoon. Choice C (5:17 AM) is incorrect because 15 is in the afternoon, not morning. Choice D (9:17 AM) is incorrect because 15 is in the afternoon, not morning.

Correct Answer: A

Rationale: The correct answer is A (250 grams). To calculate the full RDI, we use the formula: RDI = Consumed Amount / Percentage Consumed. Given, Consumed Amount = 75 grams and Percentage Consumed = 30%. Therefore, RDI = 75 / 0.30 = 250 grams. The other choices are incorrect because they do not match the calculated value based on the given information. Choice B, C, and D are all higher than the correct calculation of 250 grams, so they do not align with the required amount based on the 30% consumption.
