HESI A2 Math Practice Test 2023

Correct Answer: C

Rationale: To solve for x, we first cross multiply: x*500 = 250*3. Simplifying gives x = 750/500 = 1.5. Choice C is correct. Choice A (150) and D (60) are incorrect as they are not the solutions to the equation. Choice B (25.5) is incorrect as it does not match the result of the calculation.

Correct Answer: C

Rationale: To convert quarts to ounces, we know that 1 quart is equal to 32 ounces. Therefore, to find out how many ounces are in 4.5 quarts, we multiply 4.5 by 32, which equals 144 ounces. So, the correct answer is C (144 ounces). Incorrect Choices: A: 120 ounces - This is incorrect because it does not account for the correct conversion factor of 1 quart to 32 ounces. B: 120 ounces - Same as choice A, incorrect conversion factor used. D: 128 ounces - This is incorrect as it is not the correct result of multiplying 4.5 quarts by 32 ounces per quart.

Correct Answer: A

Rationale: To add fractions, we need a common denominator, which for 3, 6, and 5 is 30. So, we rewrite the fractions with a denominator of 30: 20/30 + 5/30 + 12/30 = 37/30. Simplifying 37/30 as 1 & 7/30 gives us the correct answer, choice A. The other choices are incorrect because they do not reflect the accurate sum of the fractions. Choice B is incorrect as it simplifies to 1 & 1/15, not 1 & 7/30. Choice C simplifies to 2/5, which is not the sum of the given fractions. Choice D simplifies to 3/4, which is also not the sum of the fractions provided.

Correct Answer: C

Rationale: To convert milliliters to liters, you need to divide by 1,000 since there are 1,000 milliliters in 1 liter. So, 2,000 milliliters divided by 1,000 equals 2 liters. Therefore, the correct answer is C: 2 liters. Choice A is incorrect as it incorrectly doubles the conversion factor. Choice B is incorrect as it doesn't account for the conversion from milliliters to liters. Choice D is incorrect as it duplicates choice A.

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.
