HESI A2 Math Practice Test 2023

Correct Answer: C

Rationale: To convert gallons to ounces, we know that 1 gallon equals 128 ounces. Therefore, to find out how many ounces are in 2.5 gallons, we multiply 2.5 by 128. 2.5 * 128 = 320 ounces. Therefore, the correct answer is C: 320 ounces. Other choices are incorrect because they do not correctly calculate the conversion from gallons to ounces. A, B, and D do not consider the correct conversion factor of 128 ounces per gallon.

Correct Answer: A

Rationale: The correct answer is A: 5.3 hours. To calculate the total time taken, add the time taken for each set of 6 miles: 1 hour + 1.2 hours + 1.5 hours + 1.6 hours = 5.3 hours. This is the total time taken by the female to complete the 24-mile course. Choice B (4.5 hours) is incorrect because it does not account for the increasing time taken for each set of 6 miles. Choice C (6 hours) is incorrect as it assumes each set of 6 miles took the same amount of time, which is not the case. Choice D (7 hours) is incorrect as it overestimates the total time taken.

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: D

Rationale: To find 80% of $500, you multiply $500 by 0.80. 0.80 represents 80% in decimal form. So, $500 x 0.80 = $400. Choice D is correct. Choice A is incorrect because $425 is 85% of $500. Choice B is incorrect because $450 is 90% of $500. Choice C is incorrect because $350 is 70% of $500.

Correct Answer: B

Rationale: The correct answer is B (2.2). To convert pounds to kilograms, you need to divide the weight in pounds by 2.2. This is because 1 pound is approximately equal to 0.454 kilograms. Therefore, by dividing the weight in pounds by 2.2, you are essentially converting pounds to kilograms. Choice A (1.8) is incorrect because it is not the accurate conversion factor for pounds to kilograms. Choice C (2.5) is also incorrect as it is not the standard conversion factor. Choice D (2) is not correct either, as it does not accurately convert pounds to kilograms.
