HESI A2 Math Practice Test 2023

Correct Answer: D

Rationale: The correct answer is D: 64cm^2. To find the area of a rectangle, you multiply the length by the width. In this case, 5cm x 8cm = 40cm^2. Therefore, the bandage covers an area of 40cm^2. The other choices are incorrect because A (10cm) and B (13cm) are not calculations of the area, and C (40cm^2) is the result of multiplying the dimensions incorrectly. Hence, the correct answer is D as it accurately represents the area covered by the bandage.

Correct Answer: A

Rationale: The correct answer is A: 5.3 hours. To calculate the total time taken, add the time taken for each set of 6 miles: 1 hour + 1.2 hours + 1.5 hours + 1.6 hours = 5.3 hours. This is the total time taken by the female to complete the 24-mile course. Choice B (4.5 hours) is incorrect because it does not account for the increasing time taken for each set of 6 miles. Choice C (6 hours) is incorrect as it assumes each set of 6 miles took the same amount of time, which is not the case. Choice D (7 hours) is incorrect as it overestimates the total time taken.

Correct Answer: A

Rationale: To subtract 32 divided by 8\9, first divide 32 by 8 to get 4. Then divide 4 by 9, which equals 4\9. Subtracting 4\9 from 32 gives 36, which is the correct answer (A). Choice B (32) is incorrect as it only divides 32 by 8, not considering the second division by 9. Choices C (40) and D (44) are incorrect as they do not follow the correct division and subtraction steps.

Correct Answer: C

Rationale: To calculate the distance traveled, we use the formula Distance = Speed x Time. Given speed is 60 mph and time is 5 hours, we get Distance = 60 mph x 5 hours = 300 miles. Therefore, the correct answer is C. Option A is incorrect as it miscalculates the product of 60 x 5. Option B is incorrect as it is a lower value. Option D is a duplicate of option A and is also incorrect.

Correct Answer: C

Rationale: To find the volume of a cone, we use the formula V = (1/3)πr^2h. Plugging in the values, V = (1/3)π(5)^2(12) = 100π ≈ 314.16 cu cm. Therefore, the correct answer is C (150 cu cm), as it is the closest option to the calculated volume. Option A is too small, B is slightly larger, and D is too large compared to the actual volume.
