HESI A2 Math Practice Exam Questions

Question 1 of 5

How many millimeters are in 5 meters?

Correct Answer: A

Rationale: To convert meters to millimeters, we know that 1 meter is equal to 1000 millimeters. Therefore, to find how many millimeters are in 5 meters, we multiply 5 by 1000 which equals 5000 millimeters. Choice A (5000 mm) is correct. Choices B, C, and D are incorrect as they do not accurately convert 5 meters to millimeters. Choice B (4000 mm) is incorrect because it underestimates the conversion. Choice C (5500 mm) is incorrect as it overestimates the conversion. Choice D (6000 mm) is also incorrect as it overestimates the conversion.

Question 2 of 5

If 9 out of 75 band members missed practice, what percentage of band members missed practice?

Correct Answer: B

Rationale: To find the percentage of band members who missed practice, we need to calculate the ratio of band members who missed practice to the total band members. 9 out of 75 band members missed practice, so the ratio is 9/75 = 0.12 or 12%. Therefore, the correct answer is B (12%). Choice A (10%) is incorrect as 9 out of 75 is not equivalent to 10%. Choice C (15%) is incorrect as 9 out of 75 is not equivalent to 15%. Choice D (18%) is incorrect as 9 out of 75 is not equivalent to 18%.

Question 3 of 5

Evaluate the following expression: -x + y + xy, when x = 4 and y = 2.

Correct Answer: B

Rationale: To evaluate the expression -x + y + xy with x = 4 and y = 2: Substitute x and y values: -4 + 2 + 4(2) = -4 + 2 + 8 = 6 (B). Explanation: Follow the order of operations (PEMDAS) to simplify the expression correctly. Option A is incorrect as it does not match the result obtained. Option C is incorrect as it does not consider the negative sign in the expression. Option D is incorrect as it does not account for the addition and multiplication operations in the expression.

Question 4 of 5

If Bill has 5.5 vacation days left for the rest of the year and 3.25 sick days left, how many days will he have off work if he uses all of this time?

Correct Answer: A

Rationale: To find the total days off work, we add Bill's remaining vacation days (5.5) and sick days (3.25). 5.5 + 3.25 = 8.75 Therefore, Bill will have 8.75 days off work if he uses all of his remaining vacation and sick days. Choice A (8.75) is correct because it accurately represents the total days off. Choices B, C, and D are incorrect as they do not correctly calculate the total days off based on the given information.

Question 5 of 5

What is the result of 0.003 x 4.23?

Correct Answer: A

Rationale: To find the result of 0.003 x 4.23, you multiply the numbers: 0.003 x 4.23 = 0.01269. This is the correct answer (A) because when you multiply decimals, you count the total number of decimal places in the factors and place the same number of decimal places in the product. The other choices are incorrect because they do not match the correct calculation. Choice B has an incorrect digit in the thousandths place, choice C has an incorrect digit in the hundredths place, and choice D has an incorrect digit in the tenths place. Therefore, the correct answer is A, 0.01269.
