Correct Answer: A

Rationale: The correct answer is A because an exponent is a number that indicates how many times a base number is multiplied by itself. For example, in 2^3, 3 is the exponent telling us to multiply 2 by itself 3 times. Choice B is incorrect because an exponent is not the number being multiplied, but the number indicating how many times to multiply. Choice C is incorrect as an exponent does not involve division. Choice D is incorrect as it refers specifically to squaring a number, whereas exponents can apply to any power beyond just squaring.

Correct Answer: D

Rationale: To find the number of blue gumballs, we first calculate the percentage of blue gumballs: 100% - (20% + 30% + 5% + 10%) = 35% blue gumballs. Since there are 120 gumballs in total, there are 35% of 120 = 42 blue gumballs. To find the difference between the number of blue and yellow gumballs, we subtract the number of yellow gumballs (5% of 120 = 6) from the number of blue gumballs: 42 - 6 = 36. Therefore, the correct answer is D: 36. Summary: A: 48 - Incorrect. This is not the correct difference between blue and yellow gumballs. B: 30 - Incorrect. This is not the correct difference between blue and yellow gumballs. C: 42 - Incorrect. This is the total number of blue gumb

Correct Answer: D

Rationale: The correct answer is D: 17.8 cm. To convert inches to centimeters, we use the conversion factor 1 inch = 2.54 cm. So, to find the metric equivalent of 7 inches, we multiply 7 by 2.54, which equals 17.78 cm. Rounding to one decimal place gives us 17.8 cm. Explanation for incorrect choices: A: 3.2 cm - This is incorrect as it is too small for the conversion of 7 inches. B: 2.8 cm - This is also too small for the conversion of 7 inches. C: 15.4 cm - This is incorrect as it is close to the correct answer, but not the exact conversion based on the given conversion factor.

Correct Answer: A

Rationale: The correct answer is A: 0.75 hectares. To calculate the area of the soccer field in square meters, you multiply the length by the width (100m x 75m = 7500 square meters). To convert this to hectares, you divide by 10,000 (7500 ÷ 10,000 = 0.75 hectares). Choice B (7.5 hectares) is incorrect because it is 10 times the correct answer. Choice C (7,500 hectares) is incorrect because it is 1,000 times the correct answer. Choice D (75,000,000 hectares) is incorrect because it is 100,000 times the correct answer.
