Final answer:
Troy's group used a total of 40 inches of tape to secure the newspapers. Initially, they had 72 inches of tape (2 yards). After the activity, they have 32 inches of tape left.
Step-by-step explanation:
The student's question asks for help with a math problem involving tape measurement and subtraction to determine how much tape is left after an activity. Troy's science class is attempting to build the tallest tower using newspapers and tape, and each group has been provided with 10 newspapers and 2 yards of tape. If Troy's group rolls each newspaper and uses 4 inches of tape to secure each one, we need to calculate the total amount of tape used and subtract that from the total amount provided to know how much tape remains.
First, we need to convert the total amount of tape from yards to inches since the tape used for each newspaper is given in inches. There are 36 inches in a yard, so 2 yards equal 72 inches. Next, we determine how much tape is used in total by multiplying the number of newspapers by the length of tape for each one. With 10 newspapers using 4 inches of tape each, that equals 40 inches of tape used. Finally, to find out how much tape Troy's group has left, we subtract the total used from the total provided.
Calculation:
- Convert yards to inches: 2 yards = 2 * 36 inches = 72 inches
- Multiply the number of newspapers by the tape used per newspaper: 10 newspapers * 4 inches per newspaper = 40 inches
- Subtract the total tape used from the total tape provided: 72 inches - 40 inches = 32 inches
Troy's group has
32 inches
of tape left after securing all their newspaper rolls.
