Explanation:

Question 1:

Step1: Convert ounces to pounds

We know that 1 pound = 16 ounces, so 8 ounces = $\frac{8}{16}$ = 0.5 pounds.

Step2: Calculate tare weight

Gross weight is 8.75 pounds, and the weight of the empty case is 0.5 pounds. Tare weight = Gross weight - Net weight? Wait, no, tare weight is the weight of the container. Wait, the problem says: A case of kiwifruit has a gross weight of 8.75 pounds. The weight of the empty case is 8 ounces. What is the tare weight of the case? Wait, tare weight is the weight of the container (empty case), but we need to convert 8 ounces to pounds. 8 ounces is 8/16 = 0.5 pounds? Wait, no, maybe I misread. Wait, the options are 9.25, 9.75, 8.25, 8.50 pounds. Wait, maybe gross weight is the weight of the case plus the kiwifruit. Wait, no, the problem says "the weight of the empty case is 8 ounces". Tare weight is the weight of the empty case. So we need to convert 8 ounces to pounds. 1 pound = 16 ounces, so 8 ounces = 8/16 = 0.5 pounds. But the gross weight is 8.75 pounds? Wait, maybe the problem is: A case of kiwifruit has a gross weight of 8.75 pounds. The weight of the empty case (tare weight) is 8 ounces. Wait, no, maybe the net weight is 8.75 - tare weight? No, the question is "What is the tare weight of the case?" and the empty case is 8 ounces. So convert 8 ounces to pounds: 8/16 = 0.5 pounds. But the options are 8.25, 8.50, etc. Wait, maybe I misread the problem. Let me check again. "A case of kiwifruit has a gross weight of 8.75 pounds. The weight of the empty case is 8 ounces. What is the tare weight of the case?" Wait, tare weight is the weight of the empty case, so it's 8 ounces, which is 0.5 pounds. But the options don't have 0.5. Wait, maybe the gross weight is the weight of the kiwifruit, and the tare weight is the case, and we need to find the gross weight (case + kiwifruit). Wait, the problem says "the weight of the empty case is 8 ounces" (tare weight), and the net weight (kiwifruit) is 8.75 pounds? No, that doesn't make sense. Wait, maybe the problem is: A case of kiwifruit has a gross weight of 8.75 pounds. The weight of the empty case (tare) is 8 ounces. What is the tare weight in pounds? 8 ounces is 0.5 pounds, but the options are 9.25, 9.75, 8.25, 8.50. Wait, maybe the gross weight is the case plus the kiwifruit, and the net weight (kiwifruit) is 8.75 pounds, and the tare (case) is 8 ounces (0.5 pounds), so gross weight is 8.75 + 0.5 = 9.25 pounds. Ah, that must be it. So:

Step1: Convert 8 ounces to pounds

8 ounces = $\frac{8}{16}$ = 0.5 pounds.

Step2: Calculate gross weight (tare + net)

Net weight (kiwifruit) is 8.75 pounds, tare (case) is 0.5 pounds. Gross weight = 8.75 + 0.5 = 9.25 pounds.

When fruits are cut and exposed to air, the browning reaction is due to oxidation, where enzymes react with oxygen. Acidulation (A) is adding acid, Radiation (B) is energy emission, Shrinkage (D) is reduction in size. Oxidation (C) matches the browning of cut fruits.

Step1: Convert 5 pounds to ounces

1 pound = 16 ounces, so 5 pounds = 5 * 16 = 80 ounces.

Step2: Subtract discarded ounces

4 oz is discarded, so remaining after cleaning: 80 - 4 = 76 ounces.

Step3: Subtract portion size

Each portion is 2 oz, so number of portions: 76 / 2 = 38. Wait, no: Wait, the problem says "Green beans come packed in 5 - pound cases. After cleaning the case, 4 oz. of green beans is discarded. If 2 oz. of green beans is the portion size, how many portions remain in the case?" Wait, 5 pounds is 80 ounces. After cleaning, 4 oz is discarded, so 80 - 4 = 76 ounces left. Then, each portion is 2 oz, so number of portions is 76 / 2 = 38. Wait, but the options are 41, 42, 36, 38. So 38 is option D.

Step1: Convert 5 pounds to ounces

5 pounds = 5 * 16 = 80 ounces.

Step2: Subtract discarded amount

80 - 4 = 76 ounces.

Step3: Divide by portion size

76 / 2 = 38.

Answer:

A. 9.25 pounds
