Answer:

1. P=10+2w;

2. P=2l+6.

Step-by-step explanation:

Mr. Frame uses the function P=2l+2w to find the perimeter, where l is the length and w is the width.

1. If l=5 ft, then

P=2\cdot 5+2w,\\ \\P=10+2w.

2. If w=3 ft, then

P=2l+2\cdot 3,\\ \\P=2l+6.

A teacher needs 70 lengths of string cut to 40cm each. If balls of string are 10 m long, how many balls will be needed.
Genrish500 [490]

Answer:

3

Step-by-step explanation:

A ball is 10 meters. Since 100 centimeters are in a meter, each ball has 100*10 = 1000 centimeters.

The teacher needs 70 strings each 40 centimeters. The total amount they need is 70*40 = 2800 centimeters.

Since a ball has 1000 centimeters, 2800 centimeters will need 3 balls for a total of 3000 centimeters.
