Question 1 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.
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
What number is represented by the Roman Numerals XLIV?
Correct Answer: C
Rationale: The Roman numeral XLIV represents the number 44. Here's the breakdown: - "XL" is 40 in Roman numerals. - Adding "IV" (4) to XL gives us 44. Therefore, the correct answer is C. Other choices are incorrect because: - A (34): This is incorrect as XL is 40, not 30. - B (54): XL is 40, not 50. - D (24): XL is 40, not 20.
Question 4 of 5
An IV drip delivers medication at a rate of 40 drops per minute. Each drop contains 0.05 milliliters of the medication. How many milliliters of medication are delivered in one hour?
Correct Answer: D
Rationale: To calculate the amount of medication delivered in one hour, first find the amount delivered in one minute: 40 drops/min * 0.05 mL/drop = 2 mL/min. Then, multiply by the number of minutes in an hour: 2 mL/min * 60 min = 120 mL. Therefore, the correct answer is D (120 milliliters). Summary: A: Incorrect. Not enough medication delivered. B: Incorrect. Not enough medication delivered. C: Incorrect. Too low of an amount delivered.
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.
