HESI A2 Quizlet Math

1. What is the result of adding 7 2/3 and 5 5/12?

Correct answer: C

Rationale: To add mixed numbers, convert them to improper fractions. 7 2/3 = 23/3 and 5 5/12 = 65/12. Adding them results in 233/12. Converting this improper fraction back to a mixed number gives 19 5/12, which simplifies to 13 1/12. Therefore, the correct answer is 13 1/12.\nChoice A (11 1/12) is incorrect as it does not represent the correct sum of the given mixed numbers. Choice B (12 1/4) is incorrect as it is not the result of adding 7 2/3 and 5 5/12. Choice D (14 1/6) is incorrect as it is not the correct sum of the provided mixed numbers.

2. If a patient's condition is deteriorating, he is ______.

Correct answer: B

Rationale: The correct answer is 'B: Getting worse.' When a patient's condition is deteriorating, it means that their health is declining or worsening. Choices A, C, and D are incorrect because improving, stabilizing, and reversing all indicate positive changes or holding steady, which are the opposite of deteriorating.

3. Solve for x: 4x - 8 = 16.

Correct answer: D

Rationale: To solve the equation 4x - 8 = 16, first, add 8 to both sides to isolate 4x: 4x = 24. Then, divide by 4 to solve for x: x = 6. Therefore, the correct answer is D. Choice A, x = 7, is incorrect as the correct solution is x = 6. Choices B and C are duplicates of choice A and are also incorrect.

4. A marathon runner completes 21.4 miles and burns 2276 calories. What is her rate of calories burned per mile?

Correct answer: B

Rationale: To find the rate of calories burned per mile, divide the total calories burned by the total miles run. In this case, 2276 calories รท 21.4 miles = 106.4 calories per mile. Therefore, the correct answer is B. Choice A (106.3) is incorrect because it is slightly lower than the calculated value. Choice C (106.355) is incorrect as it is a more precise value than the calculation result. Choice D (106.36) is also incorrect as it is a more precise value than the calculated answer.

5. When a child has a stuffy nose, they might find it hard to?

Correct answer: A

Rationale: The correct answer is 'A: Breathe.' When a child has a stuffy nose, the difficulty they experience is related to the action of breathing. 'Breathing' (choice B) is a gerund and doesn't fit the context of the question. 'Breath' (choice C) is a noun, not the correct verb form. 'Breadth' (choice D) refers to the extent or width of something and is unrelated to the child's difficulty due to a stuffy nose.
