Correct Answer: B

Rationale: Failed to generate a rationale after 5 retries.

Correct Answer: A

Rationale: To find the diameter of a circle from its circumference, we use the formula: Diameter = Circumference / π. Given the circumference is 49 feet, we can calculate the diameter by dividing 49 by π (approximately 3.14), resulting in 15.6 feet, which is choice A. Option B, 17.8 feet, is incorrect as it does not match the calculation. Option C, 49 feet, is the circumference, not the diameter. Option D, 153.9 feet, is incorrect as it is not the result of dividing the circumference by π. Therefore, choice A is the correct answer based on the formula for finding the diameter of a circle.

Correct Answer: C

Rationale: To find the number of hosts, we first need to determine the total number of parts in the ratio, which is 9 + 2 + 1 = 12 parts. Then, for hosts, we calculate (2/12) * 36 = 6 hosts. Therefore, the correct answer is C. Choice A (3) is incorrect because it does not properly reflect the ratio provided. Choice B (4) is incorrect as well because it does not align with the ratio. Choice D (8) is incorrect because it exceeds the total number of employees in the restaurant.

Correct Answer: B

Rationale: To convert 8 pounds and 8 ounces to kilograms, first convert pounds to kilograms (1 lb = 0.453592 kg) and ounces to kilograms (1 oz = 0.0283495 kg). So, 8 lbs + 8 oz is approximately 3.9 kg. Therefore, choice B (3.9 kilograms) is the correct equivalent. Choice A (3.6 kg) is too low, and choices C (17.6 kg) and D (18.7 kg) are too high based on the conversion rates.

Correct Answer: B

Rationale: The correct answer is B because when simplifying the expression 14 - 7 + (-7), we get 14 - 7 - 7 = 0, which is not a negative value. A: (-3)(-1)(2)(-1) simplifies to 6, which is a positive value. C: 7 - 10 + (-8) simplifies to -11, a negative value. D: -5(-2)(-3) simplifies to -30, a negative value. Thus, B is the only choice that results in a non-negative value.
