HESI A2 Quizlet Math Questions

Question 1 of 5

The recipe called for 3 1/2 pints of sour cream. How many cups of sour cream would that be equivalent to?

Correct Answer: B

Rationale: To convert 3 1/2 pints to cups, we know that 1 pint equals 2 cups. Therefore, 3 1/2 pints would be 7 cups (3 pints = 6 cups, 1/2 pint = 1 cup). So, the correct answer is B. Choice A (5 cups) is incorrect because it doesn't account for the additional 1/2 pint. Choice C (6 cups) is incorrect as it only considers 3 pints. Choice D (4 cups) is incorrect because it doesn't account for the additional 1/2 pint.

Question 2 of 5

The formula for calculating ideal body weight (IBW) for men is IBW (kg) = 50 + 2.3 * (height in cm - 150). If a man is 180cm tall, what is his ideal body weight?

Correct Answer: B

Rationale: To calculate the ideal body weight for a man who is 180cm tall: IBW = 50 + 2.3 * (180 - 150) = 50 + 2.3 * 30 = 50 + 69 = 119kg Therefore, the correct answer is B: 71kg. This is because the calculation results in an ideal body weight of 119kg, which corresponds to option B. The other choices (A, C, D) are incorrect as they do not match the calculated value.

Question 3 of 5

Calculate the product of the following decimals: (0.67)(0.09)

Correct Answer: A

Rationale: To calculate the product of decimals, you multiply the numbers as if they were whole numbers, then adjust the decimal places. Step 1: Multiply 67 by 9 (67 * 9 = 603) Step 2: Count the total decimal places in the original numbers (2) Step 3: Place the decimal point in the product by counting from the right the same number of places as in step 2, which gives 0.0603. Therefore, the correct answer is A: 0.0603. Other choices are incorrect because they do not follow the correct multiplication and decimal placement process. B: 0.6, C: 0.603, and D: 0.06 have incorrect decimal placement or incorrect multiplication results.

Question 4 of 5

In a local baseball team, 4 players, which represent 5% of the team, have long hair, and the rest have short hair. How many short-haired players are there on the team?

Correct Answer: C

Rationale: To solve this problem, we first find the total number of players on the team by setting up a proportion: 4 players represent 5%, so 1% is equal to 0.8 players. Thus, the total number of players is 4 divided by 0.05, which equals 80 players. Since 4 players have long hair, there are 80 - 4 = 76 players with short hair. The correct answer is C. Option A, B, and D are incorrect because they do not align with the calculated total number of players on the team.

Question 5 of 5

How many meters are in 3 kilometers?

Correct Answer: A

Rationale: To convert kilometers to meters, we need to multiply by 1000 since there are 1000 meters in 1 kilometer. Therefore, 3 kilometers x 1000 = 3000 meters. This is why choice A (3000 meters) is correct. Choices B, C, and D are incorrect because they do not follow the conversion factor of 1000 meters in 1 kilometer. Choice B (2000 meters) is too low, choice C (3500 meters) is too high, and choice D (2500 meters) is also too low.
