HESI A2 Math Practice Test 2023

Correct Answer: A

Rationale: To convert millimeters to meters, we divide by 1000 since there are 1000 millimeters in a meter. Therefore, 3000 millimeters divided by 1000 equals 3 meters. Choice A is correct. Choices B, C, and D are incorrect because they do not correctly convert millimeters to meters. Choice B is 30 times the correct answer, choice C is 10 times less, and choice D is 100 times more.

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: 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.

Correct Answer: B

Rationale: To find the perimeter of the table, we add the lengths of all four sides. Since opposite sides are equal, we have two pairs of sides with lengths 75cm and 50cm each. Therefore, the perimeter is 2(75cm) + 2(50cm) = 150cm. Choice A is incorrect because it only considers one pair of sides. Choice C is incorrect as it adds all sides together without considering the pairs. Choice D is incorrect as it only considers one side length.

Correct Answer: B

Rationale: To convert milliliters to liters, you divide by 1000 since 1 liter is equal to 1000 milliliters. So, 8000 milliliters divided by 1000 equals 8 liters. Therefore, the correct answer is B: 8 liters. Explanation for incorrect choices: A: 0.8 liters - Incorrect because the conversion is 8000 milliliters divided by 1000 equals 8 liters, not 0.8 liters. C: 0.8 liters - Same as choice A, incorrect conversion. D: 0.08 liters - Incorrect because the conversion is 8000 milliliters divided by 1000 equals 8 liters, not 0.08 liters.
