Final answer:
By determining the value of 13, we can answer two Mathematics questions: Aaron can fill 13 one-gram sugar packets with his 13 grams of sugar, and Joanna ate a total of 6 slices of pizza after having 5 for lunch and 1 more at snacktime.
Step-by-step explanation:
The two questions that can be answered by determining the value of 13 are:
- C. Aaron has 13 grams of sugar he is using to fill 1-gram packets. How many packets can he fill?
- D. Joanna had 5 slices of pizza for lunch. She ate another slice at snacktime. How much pizza did Joanna eat?
To answer question C, since Aaron has 13 grams of sugar and each packet requires 1 gram, he can fill 13 packets. This is simply determining the number of 1-gram packets that can be made from 13 grams by dividing 13 grams by 1 gram per packet, which equals 13 packets.
To answer question D, if Joanna had 5 slices of pizza for lunch and then ate another slice at snack time, she ate a total of 6 slices. Here, we are determining the total amount by adding the number of slices eaten at two different times, 5 slices + 1 slice, to get 6 slices.
