Math HESI A2 Practice Test

Correct Answer: D

Rationale: To solve x/5 = 3/10, first cross multiply to get 10x = 15. Then divide both sides by 10 to isolate x, giving x = 1.5. This is the correct answer as it satisfies the original equation. Choices A, B, and C are incorrect as they do not match the result obtained from solving the equation step by step.

Correct Answer: C

Rationale: To convert quarts to ounces, you need to know that 1 quart equals 32 ounces. Therefore, 1.5 quarts would be 1.5 x 32 = 48 ounces. So, the correct answer is C (48 ounces). Choice A is incorrect as it incorrectly converts quarts to ounces. Choice B is half of the correct conversion. Choice D is double the correct conversion.

Correct Answer: C

Rationale: The nurse works from 1300 to 2000, which translates to 1 PM to 8 PM. To calculate the hours worked, subtract the start time from the end time: 8 PM - 1 PM = 7 hours. Therefore, the correct answer is C (7 hours). Choice A (8 hours) is incorrect as it includes the end time, Choice B (11 hours) is incorrect as it adds extra hours, and Choice D (12 hours) is incorrect as it adds both the start and end times.

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.

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.
