Question

1. 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? a. 9.25 pounds b. 9.75 pounds c. 8.25 pounds d. 8.50 pounds 2. many fruits brown once they are cut and exposed to the air; this reaction is known as a. acidulation b. radiation c. oxidation d. shrinkage 3. suppose you want to use green beans as a menu item. 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? a. 41 b. 42 c. 36 d. 38 4. broccoli, cauliflower, brussels sprouts, and kale are all members of the ______ family. a. squash b. cabbage c. root vegetable d. fungus

Explanation:

Step1: Convert ounces to pounds for question 1

Since 1 pound = 16 ounces, 8 ounces = $\frac{8}{16}=0.5$ pounds. The tare - weight is the weight of the empty case. So the tare - weight is 0.5 pounds. The gross weight is not relevant for finding tare - weight. But if we assume the question is asking for the net weight (gross weight - tare weight), net weight = 8.75 - 0.5=8.25 pounds.

Step2: Recall the concept for question 2

When fruits brown after being cut and exposed to air, it is due to oxidation. Oxidation is a chemical reaction where substances react with oxygen in the air.

Step3: Convert pounds to ounces and calculate for question 3

A 5 - pound case of green beans. Since 1 pound = 16 ounces, a 5 - pound case has 5×16 = 80 ounces. 4 ounces are discarded, so the remaining weight is 80 - 4=76 ounces. If the portion size is 2 ounces, then the number of portions is $\frac{76}{2}=38$.

Step4: Recall plant - family knowledge for question 4

Broccoli, cauliflower, brussels sprouts, and kale are all members of the cabbage family.

Answer:

1. C. 8.25 pounds
2. C. Oxidation
3. D. 38
4. B. Cabbage
