HESI A2 Math Practice Test 2024

Correct Answer: A

Rationale: The correct answer is A (250 grams). To calculate the full RDI, we use the formula: RDI = Consumed Amount / Percentage Consumed. Given, Consumed Amount = 75 grams and Percentage Consumed = 30%. Therefore, RDI = 75 / 0.30 = 250 grams. The other choices are incorrect because they do not match the calculated value based on the given information. Choice B, C, and D are all higher than the correct calculation of 250 grams, so they do not align with the required amount based on the 30% consumption.

Correct Answer: C

Rationale: To find the perimeter of the kite, we add up all the sides. Top base = 20cm Bottom base = 30cm Two equal side lengths = 15cm each Perimeter = 20 + 30 + 15 + 15 = 80cm Therefore, the correct answer is C (70cm). Choice A (55cm) is incorrect as it does not consider all the sides of the kite. Choice B (65cm) is incorrect as it does not account for the top and bottom bases. Choice D (80cm) is incorrect as it miscalculates the perimeter by not adding the side lengths correctly.

Correct Answer: D

Rationale: To find 25% of 400, you multiply 400 by 0.25 (25% as a decimal). So, 400 * 0.25 = 100. Therefore, the correct answer is D. Choice A (800) is incorrect as it is 200% of 400. Choice B (10,000) is incorrect as it is 2500% of 400. Choice C (200) is incorrect as it is 50% of 400.

Correct Answer: B

Rationale: To change a percentage to a decimal, you divide by 100. In this case, 0.03% divided by 100 equals 0.0003. Therefore, the correct answer is B. Choice A (0.03) is the original percentage value without conversion. Choice C (0.3) is 10 times the correct answer. Choice D (0.003) is 10 times smaller than the correct answer.

Correct Answer: A

Rationale: To subtract mixed numbers, start by subtracting the whole numbers (25 - 12 = 13). Then subtract the fractions separately (1/7 - 5/7 = -4/7). Combine the whole number and fraction results to get 13 - 4/7 = 12 3/7, which is choice A. Other choices are incorrect as they do not match the correct result after the subtraction process. Choice B doesn't account for the fraction subtraction correctly. Choice C is not the correct result of the subtraction. Choice D is the result of only subtracting the whole numbers, ignoring the fractions.
