HESI A2 Math Practice Test 2023 Questions
Question 1 of 5
A female ran a 24-mile course. Her first 6 miles took 1 hour, the second set of 6 miles took 1.2 hours, the third set of 6 miles took 1.5 hours, and the fourth set of 6 miles took 1.6 hours. How long did it take her to complete the course?
Correct Answer: A
Rationale: The correct answer is A: 5.3 hours. To calculate the total time taken, add the time taken for each set of 6 miles: 1 hour + 1.2 hours + 1.5 hours + 1.6 hours = 5.3 hours. This is the total time taken by the female to complete the 24-mile course. Choice B (4.5 hours) is incorrect because it does not account for the increasing time taken for each set of 6 miles. Choice C (6 hours) is incorrect as it assumes each set of 6 miles took the same amount of time, which is not the case. Choice D (7 hours) is incorrect as it overestimates the total time taken.
Question 2 of 5
A car travels 240 miles in 4 hours. What is its speed in miles per hour?
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.
Question 3 of 5
How many inches are in 1.5 yards?
Correct Answer: A
Rationale: To convert yards to inches, we know that 1 yard is equal to 36 inches. Therefore, 1.5 yards would be 1.5 x 36 = 54 inches. The correct answer is A (54 inches). Option B, 60 inches, is incorrect because it does not accurately convert 1.5 yards to inches. Option C, 72 inches, and option D, 84 inches, are also incorrect as they do not correctly represent the conversion from yards to inches in this scenario.
Question 4 of 5
Imaginary unit multiples are used to represent numbers that cannot be obtained on the number line. Which of the following is equivalent to 5i?
Correct Answer: C
Rationale: Rationale: To find an equivalent expression for 5i, we can rewrite it as 5√-1. This is because i represents √-1. Therefore, 5i is equivalent to 5 times the imaginary unit, which simplifies to 5√-1. Choice A is incorrect as it represents the negative of 5 and not an imaginary unit. Choice B, i^5, is incorrect as it represents i raised to the power of 5 and not the equivalent of 5i. Choice D, 1/5i, is incorrect as it represents the reciprocal of 5i and not the equivalent value itself.
Question 5 of 5
How many meters are in 3000 millimeters?
Correct Answer: A
Rationale: To convert millimeters to meters, we divide by 1000 since there are 1000 millimeters in a meter. Therefore, 3000 millimeters divided by 1000 equals 3 meters. Choice A is correct. Choices B, C, and D are incorrect because they do not correctly convert millimeters to meters. Choice B is 30 times the correct answer, choice C is 10 times less, and choice D is 100 times more.
