HESI A2 Quizlet Math Questions
Question 1 of 5
The price dropped from $200 to $150. By what percentage did the price decrease?
Correct Answer: D
Rationale: To calculate the percentage decrease, we use the formula: (Original Price - New Price) / Original Price * 100%. In this case, it would be (200 - 150) / 200 * 100% = 50 / 200 * 100% = 25%. Therefore, the correct answer is D (25%). Option A (5%), B (10%), and C (20%) are incorrect as they do not accurately represent the 25% decrease in price.
Question 2 of 5
What is the result of dividing 40.3 by 4.8?
Correct Answer: D
Rationale: To divide 40.3 by 4.8, we perform the division operation as follows: 40.3 ÷ 4.8 = 8.39583... Rounded to one decimal place, the result is 8.4, which is the correct answer (Choice D). Choice A (0.084) is incorrect as it is the result of dividing 40.3 by 480. Choice B (84) is incorrect as it is the result of multiplying 40.3 by 4.8. Choice C (0.84) is incorrect as it is close to the correct answer but not the precise result of the division.
Question 3 of 5
What is three tenths of 90?
Correct Answer: C
Rationale: To find three tenths of 90, we multiply 90 by 3/10. 90 * 3/10 = 270/10 = 27. Therefore, the correct answer is C: 27. Choice A (18) is incorrect as it is 2 tenths of 90. Choice B (45) is incorrect as it is half of 90. Choice D (36) is also incorrect as it is 4 tenths of 90.
Question 4 of 5
When a die is rolled, what is the probability of rolling an odd number?
Correct Answer: D
Rationale: The correct answer is D (50%). A die has 6 sides with numbers 1 to 6. There are 3 odd numbers (1, 3, 5) out of the total 6 numbers. Therefore, the probability of rolling an odd number is 3/6, which simplifies to 1/2 or 50%. Choice A (16.67%) is incorrect because it represents the probability of rolling a specific odd number (1 out of 6 options) rather than any odd number. Choice B (33.33%) is incorrect as it assumes the die has only 3 sides, each representing an odd number. Choice C (75%) is incorrect as it represents the probability of rolling an odd number as if there are only odd numbers on the die.
Question 5 of 5
What percentage of her income is left after Mary spent 15%?
Correct Answer: B
Rationale: To find the percentage of income left after spending 15%, you subtract 15% from 100% (total income percentage). So, 100% - 15% = 85% left. Therefore, choice B (85%) is correct. Choices A, C, and D are incorrect as they do not accurately represent the remaining percentage of income after spending.
