Math HESI A2 Practice Test

Correct Answer: B

Rationale: To measure 15ml of liquid using a syringe that holds 3ml, you would need to divide 15ml by 3ml to determine the number of syringes needed. 15ml ÷ 3ml = 5 syringes. Therefore, the correct answer is B: 5 syringes. Choice A (3 syringes) is too few, choice C (7 syringes) and choice D (9 syringes) are too many based on the calculation.

Correct Answer: B

Rationale: To find total calories consumed in 3 meals, multiply 500 calories/meal by 3 meals: 500 x 3 = 1500 calories. This is why choice B is correct. Choices A, C, and D are incorrect because they do not accurately calculate the total calories consumed in 3 meals. Choice A is half the correct answer, choice C is double, and choice D is the amount of calories in one meal, not for 3 meals.

Correct Answer: A

Rationale: To find the rate of calories burned per mile, divide the total calories burned (2276) by the total miles ran (21.4). So, 2276 / 21.4 = 106.4. This means the runner burns approximately 106.4 calories per mile. Choice A (106.4) is correct as it represents the correct calculation result. Choices B, C, and D are incorrect as they do not match the calculated value based on the given information.

Correct Answer: B

Rationale: To solve for x in the equation 4x + 2 = 18, we first isolate x by subtracting 2 from both sides, giving us 4x = 16. Then, we divide both sides by 4 to find x = 4, which is choice B. The correct answer is x = 4 because substituting x = 4 back into the original equation gives 4(4) + 2 = 18, which simplifies to 16 + 2 = 18, confirming that x = 4 is the solution. Choices A, C, and D are incorrect because they do not satisfy the original equation when substituted back in.

Correct Answer: C

Rationale: To convert quarts to ounces, you need to know that 1 quart equals 32 ounces. Therefore, 1.5 quarts would be 1.5 x 32 = 48 ounces. So, the correct answer is C (48 ounces). Choice A is incorrect as it incorrectly converts quarts to ounces. Choice B is half of the correct conversion. Choice D is double the correct conversion.
