HESI A2 Math Practice Test 2024 Questions
Question 1 of 5
If a student earns $120 for a 10-hour tutoring session and works 6 hours, how much did the student earn?
Correct Answer: A
Rationale: To find how much the student earned for working 6 hours, we can use the formula: Earnings = (Total pay / Total hours) x Hours worked. In this case, Earnings = ($120 / 10 hours) x 6 hours = $72. Therefore, the correct answer is A: $72. Choice B, $90, is incorrect as it does not match the calculated amount. Choice C, $80, is also incorrect. Choice D, $50, is incorrect because it is too low based on the calculated earnings for 6 hours.
Question 2 of 5
A hospital day staff consists of 25 registered nurses, 75 unlicensed assistants, five phlebotomists, six receptionists and office staff, and 45 physicians. One summer day the staff was at only 68% strength. How many people were working that day?
Correct Answer: A
Rationale: To calculate the total number of people working that day, we need to find 68% of the total staff. First, calculate 68% of each category: - Registered nurses: 25 * 0.68 = 17 - Unlicensed assistants: 75 * 0.68 = 51 - Phlebotomists: 5 * 0.68 = 3 - Receptionists and office staff: 6 * 0.68 = 4 - Physicians: 45 * 0.68 = 31 Add these numbers together: 17 + 51 + 3 + 4 + 31 = 106 people (Option A). This is the correct answer as it represents 68% of the total staff. Other options are incorrect as they do not accurately represent 68% of the total staff.
Question 3 of 5
Scientific notation is a way to represent very large or small numbers in a compact form. If a number is written as 4.82 x 10^3, what is the value of the number in standard form?
Correct Answer: C
Rationale: To convert scientific notation (4.82 x 10^3) to standard form, we multiply the coefficient (4.82) by 10 raised to the exponent (3). This gives us 4.82 x 1000 = 4820. Therefore, the value of the number in standard form is 4820. Explanation of incorrect choices: A: 0.00482 - This choice is incorrect because it represents a smaller value than the original number. B: 0.482 - This choice is incorrect as it is also smaller than the original number. D: 4820000 - This choice is incorrect as it represents a larger value than the original number.
Question 4 of 5
What is 7 1/8 + 2 4/12 equal to?
Correct Answer: A
Rationale: To solve 7 1/8 + 2 4/12, first convert 2 4/12 to an improper fraction: 2 4/12 = 2 + 1/3 = 2 1/3 = 7/3. Now, add 7 1/8 and 7/3 by finding a common denominator, which is 24. 7 1/8 = 57/8. Add 57/8 and 7/3 to get 183/24. Simplify 183/24 to 9 11/24, which is the correct answer (A). Choices B, C, D are incorrect as they do not match the calculated result.
Question 5 of 5
An architect is designing a rectangular room. The room has an area of 225 square feet and a width of 15 feet. What is the length of the room?
Correct Answer: B
Rationale: To find the length of the room, we use the formula for the area of a rectangle: Area = Length x Width. Given that the area is 225 sq ft and the width is 15 ft, we can substitute these values into the formula: 225 = Length x 15. Solving for Length, we get Length = 225 / 15 = 15 feet. Therefore, the correct answer is B: 15 feet. Choice A (30 feet) is incorrect because it is twice the width and does not align with the given area. Choice C (25 feet) is incorrect because it does not satisfy the area requirement. Choice D (45 feet) is incorrect as it is not consistent with the given width and area.
