1. How many pounds are in 160 ounces?

• A. 10 pounds
• B. 8 pounds
• C. 5 pounds
• D. 12 pounds

Correct answer: A

Rationale: The correct answer is A: 10 pounds. There are 16 ounces in a pound. To convert 160 ounces to pounds, you need to divide 160 by 16, which equals 10 pounds. Choice B, 8 pounds, is incorrect because it does not account for the correct conversion factor. Choice C, 5 pounds, is incorrect as it is not the result of dividing 160 by 16. Choice D, 12 pounds, is incorrect as it overestimates the conversion.

2. If a helicopter flies at about 80 mph, how long will it take to travel 140 miles?

• A. 1 hour 15 minutes
• B. 1 hour 20 minutes
• C. 1 hour 30 minutes
• D. 1 hour 45 minutes

Correct answer: D

Rationale: To calculate the time it takes to travel a certain distance, we can use the formula Time = Distance / Speed. In this case, the helicopter is flying at 80 mph and needs to travel 140 miles. Therefore, Time = 140 miles / 80 mph = 1.75 hours or 1 hour and 45 minutes. So, the correct answer is D. 1 hour 45 minutes. Choices A, B, and C are incorrect as they do not represent the accurate time it takes for the helicopter to cover the 140-mile distance at 80 mph.

3. A newborn weighs 8 pounds 5 ounces. There are 453.59 grams per pound. What is the infant's weight in grams?

• A. A. 2268 grams
• B. B. 3629 grams
• C. C. 3770 grams
• D. D. 3856 grams

Correct answer: B

Rationale: To convert pounds and ounces to grams: 8 pounds = 8 × 453.59 = 3,628.72 grams. 5 ounces = (5 ÷ 16) × 453.59 = 141.75 grams. Total weight = 3,628.72 + 141.75 = 3,629 grams (rounded). Therefore, the infant's weight is approximately 3,629 grams. Choice A, 2268 grams, is incorrect as it does not account for the weight in ounces. Choice C, 3770 grams, is incorrect as it is not the accurate converted weight. Choice D, 3856 grams, is incorrect as it does not consider the conversion of ounces to grams.

4. 81:X::9:27. Find X.

• A. 3
• B. 27
• C. 21
• D. 9

Correct answer: B

Rationale: To find X in the given proportion 81:X::9:27, you can set up the equation 81/X = 9/27. Cross-multiplying gives 81 * 27 = 9 * X, which simplifies to 2187 = 9X. Dividing both sides by 9 results in X = 27. Therefore, the correct answer is B. Choice A (3) is incorrect as it does not satisfy the proportion. Choice C (21) is incorrect as it is not the correct value to make the proportion valid. Choice D (9) is incorrect as it does not align with the proportion provided.

5. A syringe holds 3ml of liquid. How many syringes are needed to measure 15ml of liquid?

• A. 3
• B. 5
• C. 7
• D. 9

Correct answer: B

Rationale: Since each syringe holds 3ml of liquid, to measure 15ml of liquid, you would need to divide 15ml by 3ml/syringe. This calculation gives you 5 syringes needed to measure 15ml of liquid. Choice A (3 syringes) is incorrect because 3 syringes would only hold 9ml of liquid, not 15ml. Choice C (7 syringes) and Choice D (9 syringes) are incorrect as they would result in an excess amount of liquid, which is not needed.
