Math HESI A2 Practice Test

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: C

Rationale: To find the perimeter (circumference) of a circle, we use the formula C = πd, where d is the diameter. Given the diameter of the pizza is 40cm, we substitute this into the formula: C = π * 40 = 125.6cm (Choice C). This is the correct answer as it accurately calculates the circumference. Choices A, B, and D are incorrect because they do not provide the correct calculation based on the given diameter. Choice A (62.8cm) seems to be using the formula for the circumference of a circle with radius, not diameter. Choices B and D are simply incorrect calculations.

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: D

Rationale: To convert quarts to ounces, we know that 1 quart equals 32 ounces. Therefore, 3 quarts would equal 3 x 32 = 96 ounces. This makes answer choice D (96 ounces) the correct option. Choice A (64 ounces) is incorrect because it miscalculates the conversion. Choice B (32 ounces) is incorrect as it represents 1 quart, not 3 quarts. Choice C (48 ounces) is also incorrect as it is an intermediate value between the correct answer and the incorrect answer A.

Correct Answer: D

Rationale: To find 50% of 120, you multiply 120 by 0.50 (which represents 50%). So, 120 x 0.50 = 60. Therefore, the correct answer is D. Choice A (50) is incorrect because it represents the percentage value, not the result of the calculation. Choice B (50) is a duplicate of Choice A. Choice C (70) is incorrect as it is not the result of finding 50% of 120.
