1. How many centimeters are in 7 meters?

A. 7 m = 7 cm
B. 7 m = 70 cm
C. 7 m = 700 cm
D. 7 m = 7000 cm

Correct answer: C

Rationale: The prefix 'centi-' means one-hundredth. In the metric system, 1 meter is equal to 100 centimeters. Therefore, to convert meters to centimeters, you multiply the number of meters by 100. In this case, 7 meters is equal to 7 * 100 = 700 centimeters. Choice A is incorrect as it does not consider the conversion factor properly. Choice B is incorrect as it only accounts for a factor of 10 instead of 100. Choice D is incorrect as it overestimates the conversion by a factor of 10.

2. What is the number of students who said their favorite color is blue if 35% of 100 students chose blue as their favorite color?

A. 35
B. 25
C. 20
D. 10

Correct answer: A

Rationale: To find the number of students who said their favorite color is blue, we calculate 35% of 100, which is (35/100) * 100 = 35. Therefore, 35 students said their favorite color is blue. Choice B is incorrect because it represents the percentage of students who chose red. Choice C is incorrect as it represents the percentage of students who chose green. Choice D is incorrect as it represents the percentage of students who chose yellow.

3. Solve for x: 2x - 7 = 3

A. x = 4
B. x = 3
C. x = -2
D. x = 5

Correct answer: D

Rationale: To solve the equation for x, follow these steps: 2x - 7 = 3. Add 7 to both sides to isolate 2x, resulting in 2x = 10. Then, divide by 2 on both sides to find x, which gives x = 5. Therefore, the correct answer is x = 5. Choices A, B, and C are incorrect because they do not accurately solve the equation.

4. Simplify the following expression: (2/7) Ã· (5/6)

A. 2/5
B. 35/15
C. 5/21
D. 12/35

Correct answer: D

Rationale: To divide fractions, you multiply the first fraction by the reciprocal of the second fraction. In this case, (2/7) Ã· (5/6) becomes (2/7) Ã— (6/5) = 12/35. Therefore, the correct answer is 12/35. Choice A (2/5), choice B (35/15), and choice C (5/21) are incorrect because they do not correctly simplify the given expression.

5. How many cubic inches of water could the aquarium hold if it were filled completely? (Dimensions: 30 in Ã— 10 in Ã— 12 in)

A. 3600 cubic inches
B. 52 cubic inches
C. 312 cubic inches
D. 1144 cubic inches

Correct answer: A

Rationale: To find the volume of the aquarium, we multiply its length, width, and height. The formula for the volume of a rectangular solid is V = l Ã— w Ã— h. Substituting the given dimensions, we get V = 30 Ã— 10 Ã— 12 = 3600 cubic inches. Therefore, the aquarium can hold 3600 cubic inches of water. Choice B (52 cubic inches), Choice C (312 cubic inches), and Choice D (1144 cubic inches) are incorrect as they do not correctly calculate the volume of the aquarium based on its dimensions.
