Math HESI A2 Practice Test

Correct Answer: D

Rationale: To calculate the distance traveled, we use the formula Distance = Speed x Time. Given speed is 70 mph and time is 6 hours, Distance = 70 mph x 6 hours = 420 miles. Therefore, the correct answer is D. Choice A and B are the same, so they are incorrect. Choice C is incorrect as it does not match the calculated distance.

Correct Answer: A

Rationale: To find the distance traveled, we first calculate the time elapsed from 1:45 PM to 3:15 PM, which is 1.5 hours. Next, we multiply the speed of 65 mph by the time of 1.5 hours to get the distance traveled, which equals 97.5 miles. Therefore, the correct answer is A: 97.5 miles. Choice B (100 miles) is incorrect because the calculation does not result in 100 miles. Choice C (95 miles) is incorrect as it is less than the correct distance. Choice D (105 miles) is incorrect as it is greater than the correct distance calculated.

Correct Answer: A

Rationale: To add 6 3/4 and 8 1/6, first convert both mixed numbers to improper fractions: 6 3/4 = 27/4 and 8 1/6 = 49/6. Then, find a common denominator, which is 12. Now, add the fractions: 27/4 + 49/6 = 81/12 + 98/12 = 179/12. Convert the improper fraction back to a mixed number: 179/12 = 14 11/12. Therefore, the correct answer is A (14 11/12). Choices B, C, and D are incorrect because they do not match the correct calculation.

Correct Answer: B

Rationale: To convert pints to ounces, we know that 1 pint is equal to 16 ounces. Therefore, 8 1/4 pints can be calculated as 8 x 16 + 4 = 132 ounces. This is why choice B (132 oz) is correct. Choices A, C, and D are incorrect because they do not accurately represent the conversion of pints to ounces in this scenario.

Correct Answer: D

Rationale: To convert Celsius to Fahrenheit, you use the formula: Fahrenheit = (Celsius x 1.8) + 32. Given the patient's temperature is 38.5 degrees Celsius, Fahrenheit = (38.5 x 1.8) + 32 = 104.9 degrees Fahrenheit (Option D). Options A, B, and C are incorrect as they do not match the correct conversion using the formula.
