Answer:

a) 50

b) 400

c) 8

d) 200

Step-by-step explanation:

a) 5 divided 0.1

$\frac{5}{0.1} = \frac{5 \times 10}{0.1 \times 10} = \frac{50}{1} = 50$

b) 8 divided 0.02

$\frac{8}{0.02} = \frac{8 \times 100}{0.02 \times 100} = \frac{800}{2} = 400$

c) 2.4 divided 0.3

$\frac{2.4}{0.3} = \frac{2.4 \times 10}{0.3 \times 10} = \frac{24}{3} = 8$

d) 32 divided 0.16

$\frac{32}{0.16} = \frac{32 \times 100}{0.16 \times 100} = \frac{32 \times 100}{16} = 200$

Find the area of the football field when the width is 160 ft The area is ___ square feet

Lilit [14]

Answer:

We have 160 ft = ( 4x + 20 ) ft;

Then, 4x = 140;

x = 35 ft;

The length is ( 10 · 35 + 10 ) ft = 360 ft;

Area = length x width;

The area is 360 ft x 160 ft = 57600 square feet.
