HESI A2 Math Practice Test - Nurselytic

Correct Answer: A

Rationale:
To convert military time to regular time, we can drop the first two digits if they are less than 12. 1010 hours can be converted to 10:10 A.M. because it is before noon (12:00 P.M.). Military time operates on a 24-hour clock system, with 0000 hours indicating midnight and 1200 hours representing noon.
Therefore, in this case, 1010 corresponds to 10:10 A.M.
Choice B (10:10 P.M.) is incorrect as 1010 hours is in the morning, not the evening.

Choices C (1:01 A.M.) and D (1:01 P.M.) are incorrect as they do not match the given military time of 1010 hours.

Correct Answer: C

Rationale: If a horse can trot around a track twice in 10 minutes, it completes one circle in 5 minutes.
To determine how many times it will circle the track in half an hour (30 minutes), divide the total time by the time taken for one circle: 30 minutes / 5 minutes per circle = 6 times.
Therefore, the horse will circle the track 6 times at the same speed in half an hour.
Choice A, 3 times, is incorrect as it does not consider the correct time taken for a single circle.
Choice B, 5 times, is incorrect as it miscalculates the total number of circles within half an hour.
Choice D, 10 times, is incorrect as it overestimates the number of circles the horse can complete in the given time frame.

Correct Answer: A

Rationale:
To convert pounds to kilograms, you need to multiply the number of pounds by 0.4536.
Therefore, to find out how many kilograms are in 20 pounds, you would calculate 20 x 0.4536 = 9.072 kilograms, which is approximately 9 kilograms.
Choice A is correct.
Choice B (16 kilograms),
Choice C (44 kilograms), and
Choice D (3 kilograms) are all incorrect conversions of pounds to kilograms.

Correct Answer: C

Rationale: When dividing 2,032 by 25, you find that 25 goes into 2,032 a total of 81 times without exceeding it. The remainder is 7, not 28 as stated in choice B. This is because 25 * 81 = 2,025, leaving a difference of 7, not 28.
Choice A and D are incorrect because they do not correctly represent the division result of 2,032 by 25.

Correct Answer: C

Rationale: If Uri sold 28 balloons,
Tommy sold 28 + 2 = 30 balloons. Since Serena sold 6 fewer balloons than
Tommy, she sold 30 - 6 = 24 balloons.
Therefore, Serena sold 24 balloons.
Choice A, 20 balloons, is incorrect because it doesn't consider the difference in sales between Serena and
Tommy.
Choice B, 22 balloons, is incorrect as it doesn't account for the correct relation between
Tommy and Serena's sales.
Choice D, 32 balloons, is incorrect as it doesn't align with the given information about the sales differences.
