HESI A2 Math 2024

Correct Answer: C

Rationale: To find the percentage of homes she sold, divide the number of homes she sold (11) by the total number of homes (50), then multiply by 100. (11 / 50) * 100 = 22%. Therefore, she sold 22% of the homes. Choice A (16%) is incorrect because it is less than the correct percentage. Choice B (18%) is also less than the correct percentage. Choice D (24%) is greater than the correct percentage of homes she sold.

Correct Answer: C

Rationale: Teresa collected 144 baseball cards in 8 months. To find the average number of cards collected per month, we divide the total number of cards by the total months: 144 cards � 8 months = 18 cards per month. Therefore, on average, Teresa has collected 18 baseball cards per month. Choice A (12), Choice B (16), and Choice D (22) are incorrect as they do not match the correct calculation based on the information provided in the question.

Correct Answer: C

Rationale: Rationale: 1. To convert Fahrenheit to Celsius, you can use the formula: �C = (�F - 32) x 5/9. 2. Given that the patient's body temperature is 102�F, we can calculate the equivalent temperature in Celsius: �C = (102 - 32) x 5/9 �C = 70 x 5/9 �C = 350/9 �C ≈ 38.9�C, which can be rounded to 39�C. 3. A body temperature of 39�C is considered to indicate a fever. Normal body temperature typically ranges from 36.1�C to 37.2�C, so a temperature of 39�C is higher than the normal range and suggests a fever. 4. Options A and B are incorrect as they do not reflect the conversion of 102�F to �C

Correct Answer: B

Rationale: Josie bought 3 brownies for $35 each, totaling $3 x $35 = $105. She paid with a $5 bill, so the change she received would be $105 - $5 = $100. Therefore, Josie received $100 in change, which is equivalent to $0.95. Choice A, $0.85, is incorrect because the change is $100, not $0.85. Choice C, $1.05, is incorrect as it is not the correct change for the transaction. Choice D, $1.15, is incorrect as it does not accurately reflect the change Josie received.

Correct Answer: C

Rationale: To divide mixed numbers, we first convert them to improper fractions. Converting 4⅛ to an improper fraction gives us 33/8, and converting 1� gives us 3/2. Dividing 33/8 by 3/2, we multiply the first fraction by the reciprocal of the second. This gives us (33/8) / (3/2) = (33/8) * (2/3) = 66/24 = 11/4, which simplifies to 2�. Therefore, the correct answer is 2�. Choices A, B, and D are incorrect as they do not represent the correct result of dividing 4⅛ by 1�.
