HESI A2 Math Practice Test 2024

Correct Answer: A

Rationale: To solve for x, substitute x=11 into the expression x+(44/2x): 11 + (44/(2*11)) 11 + (44/22) 11 + 2 = 13 Therefore, the correct answer is D. Choice A: 2.5 is incorrect as the calculation results in 13, not 2.5. Choice B: 33 and C: 55 are also incorrect as they do not align with the correct calculation of 13.

Correct Answer: C

Rationale: The correct answer is C: 9:00 PM. To convert 2100 to standard time, subtract 12 hours from 2100 since military time is based on a 24-hour clock. 2100 - 1200 = 900, which translates to 9:00 PM. Choice A (12:00 PM) is incorrect as it would be noon, not evening. Choice B (2:00 AM) is incorrect as it represents the early morning. Choice D (2:00 PM) is incorrect as it is in the afternoon, not evening.

Correct Answer: A

Rationale: To find x in the proportion 6:10=24:x, we first calculate the ratio of the given numbers, 6/10=24/x. Simplifying, we get 0.6=24/x. Cross multiplying, we get x=24/0.6=40. Therefore, the correct answer is A. Choice B is incorrect as it does not satisfy the proportion. Choice C is incorrect as it is too large compared to the correct answer. Choice D is incorrect as it is too small compared to the correct answer.

Correct Answer: A

Rationale: To solve 5 1/3 + 3 1/2, first convert mixed numbers to improper fractions: 5 1/3 = 16/3 and 3 1/2 = 7/2. Then, add the fractions: 16/3 + 7/2 = (32+21)/6 = 53/6. Convert the result back to a mixed number: 53/6 = 8 5/6, which is choice A. Choices B, C, and D are incorrect as they do not represent the correct sum of the given mixed numbers.

Correct Answer: C

Rationale: To convert scientific notation (4.82 x 10^3) to standard form, we multiply the coefficient (4.82) by 10 raised to the exponent (3). This gives us 4.82 x 1000 = 4820. Therefore, the value of the number in standard form is 4820. Explanation of incorrect choices: A: 0.00482 - This choice is incorrect because it represents a smaller value than the original number. B: 0.482 - This choice is incorrect as it is also smaller than the original number. D: 4820000 - This choice is incorrect as it represents a larger value than the original number.
