How many centimeters are in a foot?

Correct Answer: C

Rationale: The correct answer is C: 30.48 cm. This conversion is based on the standard measurement where 1 foot is equal to 30.48 centimeters. Choice A (30 cm) is incorrect as it is a rounded-down value and not precise. Choice B (31.5 cm) is incorrect as it is not the standard conversion for feet to centimeters. Choice D (35 cm) is incorrect as it is not the accurate conversion for a foot to centimeters.

Correct Answer: A

Rationale: The correct answer is 100°C (Choice A). The boiling point of water is the temperature at which it changes from a liquid to a gas. Under normal atmospheric pressure, water boils at 100°C. Choices B, C, and D are incorrect because they do not represent the standard boiling point of water. 98°C, 99°C, and 102°C do not correspond to the temperature at which water boils under normal conditions.

Correct Answer: A

Rationale: To find the sum of 1.332 and 0.067, add the two numbers correctly: 1.332 + 0.067 = 1.399. Therefore, the correct answer is A. Choice B (1.4) is incorrect because it rounds down the sum, not considering the precise value. Choice C (1.402) is incorrect as it results from adding 1.332 and 0.070 instead of 0.067. Choice D (1.5) is not the correct sum of the given numbers.

Correct Answer: A

Rationale: The correct answer is A: 1,760. According to the standard distance conversion, there are 1,760 yards in a mile. This conversion is widely accepted and used in various fields. Choice B, 1,700, is incorrect as it does not correspond to the standard conversion. Choice C, 1,800, represents a different value and is therefore incorrect. Choice D, 1,750, is not the accurate conversion for yards in a mile and is incorrect.

Correct Answer: B

Rationale: In this question, the correct answer is B) 1:00 AM. To understand why this is the right choice, we need to decode the military time provided. In military time, 1500 hours is equivalent to 3:00 PM and 0100 hours is equivalent to 1:00 AM. Therefore, the worker's shift is from 3:00 PM to 1:00 AM, which means they will get off work at 1:00 AM. Option A) A little bit after midnight is incorrect because the worker finishes before midnight. Option C) 3:00 AM is incorrect as the shift ends at 1:00 AM. Option D) 12:30 AM is incorrect as the shift ends at 1:00 AM, not 12:30 AM. Educationally, understanding military time is essential for various professions, especially those in healthcare, aviation, and the military. It provides a standardized way to communicate time across different regions and eliminates confusion regarding AM and PM. This question reinforces the importance of converting military time to standard time for effective communication and scheduling accuracy.
