Correct Answer: D

Rationale: To find the correct answer, we first calculate how much of the burger was left after one friend ate a quarter (3/4 left). Then, the other two friends divide this among themselves equally, so each receives half of the remaining portion (3/4 * 1/2 = 3/8). Therefore, each of the other two friends received 3/8 of the burger, which is represented by choice D (8-Mar). Choices A, B, and C are incorrect because they do not accurately reflect the correct calculation of dividing the remaining portion equally between the two friends.

Correct Answer: C

Rationale: To determine the force needed to stretch the coil by 0.1 meters, we use the formula F = kx, where F is the force, k is the constant of proportionality, and x is the stretch distance. First, calculate k by dividing the given force by the stretch distance: k = 132 N / 0.07 m = 1885.7 N/m. Then, plug in the values: F = 1885.7 N/m * 0.1 m = 188.6 N. Therefore, the correct answer is C (188.6 Newtons). Choice A (92.4 N) is incorrect because it does not consider the direct proportionality between force and stretch. Choice B (1885.7 N) incorrectly assumes the force remains constant regardless of the stretch distance. Choice D (136.0 N) is not rounded to the nearest tenth as requested.

Correct Answer: A

Rationale: The correct answer is A: One. Any number raised to the power of zero equals one. This is because the rule for exponents states that any number raised to the power of zero is equal to one, regardless of the base number. This rule is derived from the properties of exponents and is a fundamental concept in mathematics. Choices B, C, and D are incorrect because raising a number to the power of zero does not result in the number itself, zero, or two. The key to remember is that any number raised to the power of zero is always equal to one, making choice A the correct answer.

Correct Answer: B

Rationale: The correct answer is B: 1 meter. This is the best estimate for the average width of a doorway because standard doorways typically range from 0.8 to 0.9 meters wide, and rounding up to 1 meter provides a reasonable estimate. Choice A (0.5 meters) is too small for a standard doorway. Choice C (10 meters) is too large and unrealistic for a doorway. Choice D (3 meters) is wider than the typical doorway width, making it an inaccurate estimate. Therefore, B is the most appropriate estimate based on common door sizes.

Correct Answer: B

Rationale: To find 31% of 426, you multiply 426 by 0.31. So, 426 * 0.31 = 132.06. Therefore, the correct answer is B: 132.06. Option A (425.69) is close but incorrect. Options C (13.7) and D (0.07) are significantly lower than the actual result, indicating they are incorrect.
