HESI A2 Math Practice Test 2023

Correct Answer: D

Rationale: To find the total number of pages the man reads per day, we multiply 2 chapters/day by 6 pages/chapter, which equals 12 pages/day. To determine how many days it will take to finish a 798-page book at 12 pages/day, we divide 798 by 12, resulting in approximately 66.5 days. This is why choice D is correct. Choice A (133 days) is incorrect because it overestimates the time needed, while choice B (399 days) and choice C (75 days) underestimate the time required to finish the book.

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: A

Rationale: To solve the equation 5x + 10 = 20, first subtract 10 from both sides to isolate the variable: 5x = 10. Then, divide by 5 on both sides to solve for x: x = 2. Therefore, the correct answer is A (4) because x = 2 satisfies the original equation. Choices B, C, and D are incorrect as they do not yield a solution that satisfies the equation.

Correct Answer: A

Rationale: To convert pints to milliliters, we need to know that 1 pint = 473.176 milliliters. Therefore, 5 pints would be 5 x 473.176 = 2365.88 milliliters. Rounding up, we get approximately 2400 milliliters. This is why choice A (2400 milliliters) is correct. Choices B, C, and D are incorrect because they do not accurately convert pints to milliliters based on the conversion factor provided.

Correct Answer: B

Rationale: To convert quarts to ounces, we know that 1 quart is equal to 32 ounces. Therefore, to find out how many ounces are in 4 quarts, we multiply 4 (quarts) by 32 (ounces/quart), which equals 128 ounces. Thus, the correct answer is B: 128 ounces. A: 64 ounces - Incorrect, this is the equivalent of 2 quarts, not 4. C: 32 ounces - Incorrect, this is the equivalent of 1 quart, not 4. D: 16 ounces - Incorrect, this is half the amount of 1 quart, not 4.
