Correct Answer: C

Rationale: When a rectangle is scaled by a factor of 2, both the length and width are multiplied by 2. The new dimensions become width = 5 * 2 = 10 inches and length = 10 * 2 = 20 inches.
Therefore, the new perimeter is calculated as 2 * (10 + 20) = 60 inches.
Choice A, B, and D are incorrect as they do not reflect the correct calculation based on scaling the dimensions of the rectangle.

Correct Answer: C

Rationale: Out of the 100 patients, 30% were men, which equals 30 male patients. It is given that 10% of the men were overweight as children, so 10% of 30 is 3, meaning 3 male patients were overweight.
Therefore, the remaining 27 male patients were not overweight as children.
Choice A, B, and D are incorrect as they do not accurately represent the number of male patients who were not overweight.

Correct Answer: B

Rationale:
To find the number of people who voted, you need to calculate 9.5% of the total population of 51,623. 9.5% of 51,623 is approximately 0.095 x 51,623 = 4,999.85, which is rounded to approximately 5,000 people.
Therefore, the correct answer is 5,000 people.
Choice A, 3,000 people, is incorrect as it is lower than the calculated value.
Choice C, 7,000 people, is incorrect as it is higher than the calculated value.
Choice D, 10,000 people, is incorrect as it is much higher than the calculated value.

Correct Answer: A

Rationale:
To calculate the number of hours a person spends sleeping when 1/4 of the day is spent sleeping, you need to find 1/4 of 24 hours. 1/4 of 24 hours is 6 hours, so the correct answer is A.
Choice B (8 hours) is incorrect because it does not correspond to 1/4 of a day.
Choice C (4 hours) is incorrect as it is half of the correct answer.
Choice D (5 hours) is incorrect as it does not match the calculation for 1/4 of a day.

Correct Answer: B

Rationale:
To find the percentage of trips where the person chose the longest route, divide the number of longest route trips (3) by the total number of trips (9) and multiply by 100. This gives (3/9) * 100 = 33.33%, which can be rounded to 33%.
Therefore, the correct answer is B.
Choice A (0.25), C (0.5), and D (0.75) are incorrect because they do not accurately represent the percentage of trips where the longest route was chosen based on the given information.
