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

How many ounces are in a gallon?

Correct Answer: B

Rationale: The correct answer is B: 128 oz. There are 128 ounces in a gallon because a gallon is a unit of volume used in the US customary system and is equivalent to 128 fluid ounces. This conversion factor is widely recognized and used in various applications. The other choices are incorrect because they do not accurately represent the conversion between gallons and ounces. Choice A (120 oz) is close but not the exact conversion. Choices C (100 oz) and D (105 oz) are significantly lower than the actual conversion of 128 oz in a gallon.

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

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 5 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.
