HESI A2 Math Practice Exam

Correct Answer: D

Rationale: To find out how many questions Brian answered correctly on the second test, we first calculate the 30% increase from his initial score of 150 questions. 30% of 150 is 45, so his new score is 150 + 45 = 195 questions. Therefore, the correct answer is D (195). Choice A (105) is incorrect because it is less than the initial score of 150. Choice B (120) is incorrect because it does not account for the 30% increase. Choice C (180) is incorrect as it is the result of adding 30% to the initial score, not the final score after the increase.

Correct Answer: A

Rationale: To find the ratio of women to the total number of students, we need to add up the number of women and divide it by the total number of students. Let's assume there are 4 women and 7 men in the class. The total number of students would be 4 (women) + 7 (men) = 11. So, the ratio of women to the total number of students is 4:11. Simplifying this ratio gives us 4:7, which is choice A. Therefore, choice A is correct. Choices B, C, and D are incorrect because they do not represent the correct ratio of women to the total number of students in the class based on the given information.

Correct Answer: B

Rationale: The correct answer is B. To determine the total length when the ropes are tied together, we convert the lengths to the same unit: 40 inches = 3.33 ft, 36 inches = 3 ft. Tying them gives 6.33 ft, which is more than the required 6 ft. This means Jeff would have enough rope. Option A is incorrect because it miscalculates the total length. Option C is incorrect as it provides the length in feet only, not considering the decimals. Option D is incorrect as it states he wouldn't have enough rope, which is not true.

Correct Answer: C

Rationale: The correct answer is C (Early afternoon to bedtime) because working from 1300 to 2000 corresponds to the time frame of early afternoon to bedtime. 1300 is 1:00 PM in the afternoon, and 2000 is 8:00 PM in the evening. This aligns with the early afternoon to evening shift. Incorrect choices: A: Early morning to early afternoon - This is incorrect as the healthcare professional's shift starts in the afternoon, not the early morning. B: Lunchtime to midnight - This is incorrect as the shift ends at 8:00 PM, not midnight. D: Midnight to sunrise - This is incorrect as the shift starts in the afternoon, not at midnight.

Correct Answer: B

Rationale: The correct answer is B: 1:00 AM. In military time, 0100 translates to 1:00 AM. When converting military time to standard time, you simply drop the leading zero and read the remaining numbers as a regular time. Choice A is incorrect because it is vague and not a specific time. Choice C is incorrect as 3:00 AM is not represented by 0100 in military time. Choice D is incorrect because 12:30 AM is not the equivalent of 0100 in military time.
