Math HESI A2 Practice Test

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: C

Rationale: To convert kilometers to meters, we need to multiply the number of kilometers by 1000 since there are 1000 meters in 1 kilometer. So, 2 kilometers x 1000 meters/kilometer = 2000 meters. Therefore, the correct answer is C: 2000 meters. Choice A (100 meters) is incorrect as it does not account for the conversion factor of 1000 meters in 1 kilometer. Choice B (200 meters) is incorrect for the same reason. Choice D (3000 meters) is incorrect as it goes beyond the actual conversion calculation.

Correct Answer: D

Rationale: To convert ounces to pounds, divide the number of ounces by 16 (since there are 16 ounces in a pound). So, 128 ounces ÷ 16 = 8 pounds. Therefore, the correct answer is D: 8 pounds. A: 16 pounds - Incorrect, as 128 ounces is equivalent to 8 pounds. B: 10 pounds - Incorrect, as it does not result from the conversion of 128 ounces. C: 12 pounds - Incorrect, as it is not the accurate conversion from ounces to pounds.

Correct Answer: C

Rationale: To find the perimeter (circumference) of a circle, we use the formula C = πd, where d is the diameter. Given the diameter of the pizza is 40cm, we substitute this into the formula: C = π * 40 = 125.6cm (Choice C). This is the correct answer as it accurately calculates the circumference. Choices A, B, and D are incorrect because they do not provide the correct calculation based on the given diameter. Choice A (62.8cm) seems to be using the formula for the circumference of a circle with radius, not diameter. Choices B and D are simply incorrect calculations.

Correct Answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1000. Therefore, to find how many milliliters are in 6 liters, you would multiply 6 by 1000, which equals 6000 milliliters. Choice A (60 milliliters) is incorrect as it is 100 times less than the correct answer. Choice C (600 milliliters) is incorrect as it is 10 times less than the correct answer. Choice D (0.6 milliliters) is incorrect as it is a decimal and represents a fraction of the milliliters in 6 liters.
