Math HESI A2 Practice Test

Correct Answer: B

Rationale: To convert liters to milliliters, you need to know that 1 liter is equal to 1000 milliliters. Therefore, to find how many milliliters are in 3 liters, you would multiply 3 by 1000, which equals 3000 milliliters. So, the correct answer is B: 3000 milliliters. A is incorrect because it is the result of multiplying 3 by 100, not 1000. C is incorrect because it is half of 3000, not the actual conversion. D is incorrect as it is one-tenth of the correct answer.

Correct Answer: D

Rationale: To calculate the distance traveled, we use the formula Distance = Speed x Time. Given speed is 70 mph and time is 6 hours, Distance = 70 mph x 6 hours = 420 miles. Therefore, the correct answer is D. Choice A and B are the same, so they are incorrect. Choice C is incorrect as it does not match the calculated distance.

Correct Answer: A

Rationale: To find the distance traveled, we first calculate the time elapsed from 1:45 PM to 3:15 PM, which is 1.5 hours. Next, we multiply the speed of 65 mph by the time of 1.5 hours to get the distance traveled, which equals 97.5 miles. Therefore, the correct answer is A: 97.5 miles. Choice B (100 miles) is incorrect because the calculation does not result in 100 miles. Choice C (95 miles) is incorrect as it is less than the correct distance. Choice D (105 miles) is incorrect as it is greater than the correct distance calculated.

Correct Answer: A

Rationale: To convert ounces to pounds, we divide by 16 (since 1 pound = 16 ounces). Therefore, 48 ounces ÷ 16 = 3 pounds. So, the correct answer is A: 3 lbs. Choice B, 6 lbs, is incorrect as it would be 48 ounces ÷ 8 (not 16). Choice C, 4 lbs, and choice D, 8 lbs, are also incorrect based on the conversion factor of 1 pound = 16 ounces.

Correct Answer: A

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in 1 kilogram. So, to find the number of grams in 10 kilograms: 10 kilograms x 1000 = 10,000 grams. Therefore, the correct answer is A: 10,000 grams. The other choices are incorrect because they do not correctly convert 10 kilograms to grams. B: 100 grams is too small, C: 1000 grams is equivalent to 1 kilogram, and D: 100,000 grams is too large.
