HESI A2 Math Practice Test 2023

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.

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.

Correct Answer: B

Rationale: To calculate speed, use the formula: speed = distance/time. In this case, the car traveled 240 miles in 4 hours. Therefore, speed = 240 miles / 4 hours = 60 mph. Choice B is correct as it represents the calculated speed accurately. Choice A (50 mph) is too low, Choice C (55 mph) is close but not accurate, and Choice D (75 mph) is too high based on the calculation.

Correct Answer: D

Rationale: The correct answer is D: 64cm^2. To find the area of a rectangle, you multiply the length by the width. In this case, 5cm x 8cm = 40cm^2. Therefore, the bandage covers an area of 40cm^2. The other choices are incorrect because A (10cm) and B (13cm) are not calculations of the area, and C (40cm^2) is the result of multiplying the dimensions incorrectly. Hence, the correct answer is D as it accurately represents the area covered by the bandage.
