Question

1. a recipe calls for 8 oz of raisins. the raisins come in 100-gram packages. how many packages do you need to buy? 40. a golf ball weighs about 45.9 grams. about how many ounces would a dozen golf balls weigh?

Explanation:

Question 39

Step1: Convert ounces to grams

We know that \( 1 \text{ oz} \approx 28.35 \text{ grams} \). So for 8 oz, the weight in grams is \( 8\times28.35 = 226.8 \) grams.

Step2: Calculate number of packages

Each package is 100 grams. To find the number of packages, we divide the total grams needed by grams per package: \( \frac{226.8}{100}=2.268 \). Since we can't buy a fraction of a package, we need to round up to 3.

Step1: Find total grams for a dozen golf balls

A dozen is 12. So total grams for 12 golf balls is \( 12\times45.9 = 550.8 \) grams.

Step2: Convert grams to ounces

Using \( 1 \text{ oz} \approx 28.35 \text{ grams} \), we divide total grams by grams per ounce: \( \frac{550.8}{28.35}\approx19.43 \).
