Question

In 20 days, the earth picks up
5.2 x 10 pounds of dust from the
atmosphere. How much dust will
it pick up in 66 days? Why do we
need to control air pollution?​

Answer 1

Step-by-step explanation:

dust tale in 20 days = 5.2x10 or 52

dust taken in 1 day = 52÷20

= 2.6

dust pickup in 66 days= 66× 2.6

= 831.6
