HESI A2 Math Practice Exam Questions

Question 1 of 5

How much paint do you need to paint the interior walls and floor of a rectangular swimming pool with dimensions 8m by 5m and a depth of 2m? (Assume one can of paint covers 10 sq m)

Correct Answer: C

Rationale: To calculate the total area to paint, we need to find the surface area of the walls and the floor separately. The surface area of the walls is 2*(8+5)*2 = 36 sq m. The floor area is 8*5 = 40 sq m. Adding these together gives 36 + 40 = 76 sq m. Since one can of paint covers 10 sq m, we need 76/10 = 7.6 cans of paint. Rounding up to the nearest whole number, we need 8 cans of paint, which is equivalent to 88 sq m. Therefore, the correct answer is C (88 sq m). Choice A (56 sq m) is incorrect as it does not consider the surface area of the floor. Choice B (72 sq m) is incorrect as it miscalculates the total area to paint. Choice D (104 sq m) is incorrect as it overestimates the amount of paint needed.

Question 2 of 5

What is the average of the numbers 14, 73, and 7?

Correct Answer: D

Rationale: To find the average of a set of numbers, you add them up and then divide by the total number of values. In this case, 14 + 73 + 7 = 94. Then, 94 divided by 3 (total numbers) gives 31.33. Therefore, choice D is correct. Choices A, B, and C are incorrect because they do not correctly calculate the average of the given numbers. A, B, and C are calculated as 14 + 73 + 7 divided by 3, which leads to incorrect averages.

Question 3 of 5

What is 2/3 of 60 + 1/5 of 75?

Correct Answer: B

Rationale: To find 2/3 of 60, multiply 60 by 2/3, which gives 40. Next, find 1/5 of 75 by multiplying 75 by 1/5, which equals 15. Adding 40 and 15 gives us 55. Therefore, the correct answer is B (55). Choice A (45) is incorrect as it only considers 2/3 of 60 without adding 1/5 of 75. Choices C (15) and D (50) also do not account for both parts of the equation.

Question 4 of 5

What number is 44 equal to 25% of?

Correct Answer: A

Rationale: To find the number that 44 is 25% of, we divide 44 by 0.25 (which is 25% expressed as a decimal). 44 / 0.25 = 176. Therefore, 44 is equal to 25% of 176. Option A (176) is the correct answer. Option B (150), C (180), and D (120) are incorrect as they do not result in 44 when multiplied by 0.25.

Question 5 of 5

What percent of 36 is 9?

Correct Answer: D

Rationale: To find what percent of 36 is 9, we divide 9 by 36: 9/36 = 0.25. To convert this decimal to a percentage, we multiply by 100: 0.25 x 100 = 25%. So, the correct answer is D (10%). Choice A (25%), B (20%), and C (15%) are incorrect as they do not correctly represent the relationship between 9 and 36.
