Question 1 of 5

How many centimeters in an inch? How many inches in a centimeter?

Correct Answer: A

Rationale: The correct answer is A: 2.54 centimeters in an inch; 0.393 inches in a centimeter. The conversion factor between inches and centimeters is 2.54, derived from the definition of an inch. To convert inches to centimeters, you multiply by 2.54. Conversely, to convert centimeters to inches, you divide by 2.54. The other choices are incorrect because they do not reflect the accurate conversion factor between inches and centimeters. B and C have incorrect conversion ratios, while D has an incorrect relationship between inches and centimeters.

Question 2 of 5

Cora skated around the rink 27 times but fell 20 times. What percentage of the time did she not fall?

Correct Answer: C

Rationale: To find the percentage of the time Cora did not fall, we subtract the number of times she fell (20) from the total times she skated (27). So, 27 - 20 = 7 times she did not fall. Then, we divide the number of times she did not fall (7) by the total times she skated (27), which is 7/27 ≈ 0.26 or 26%. Therefore, the correct answer is C. Choice A, B, and D are incorrect because they do not accurately represent the percentage of the time Cora did not fall based on the given information.

Question 3 of 5

Simplify the following expression: 6 + 7 3 - 4 2

Correct Answer: B

Rationale: To simplify the expression, we follow the order of operations (PEMDAS/BODMAS). First, we calculate the multiplication and division from left to right: 6 + 7 = 13, 13 - 4 = 9, 9 * 2 = 18. So, the correct answer is 18. Choice A is incorrect because it is the result of multiplying all the numbers together. Choice C is incorrect as it is the result of adding all the numbers together. Choice D is incorrect as it is the result of adding the first two numbers and then multiplying by the last two numbers.

Question 4 of 5

How do you find the radius of a circle when given the diameter? How do you find the radius of a circle when given the circumference?

Correct Answer: A

Rationale: Failed to generate a rationale after 5 retries.

Question 5 of 5

A patient requires a 30% decrease in the dosage of their medication. Their current dosage is 340 mg. What will their dosage be after the decrease?

Correct Answer: B

Rationale: To calculate a 30% decrease, you multiply the current dosage (340 mg) by 0.30 to find the decrease amount: 340 mg x 0.30 = 102 mg. Subtract the decrease from the current dosage to get the new dosage: 340 mg - 102 mg = 238 mg (Option B). Option A (70 mg) is incorrect as it represents a 79% decrease. Option C (270 mg) is incorrect as it does not account for the 30% decrease. Option D (340 mg) is incorrect as it does not reflect the required decrease.
