Question

in 10 days,the earth picks up 2.6×10 ke power 8 pounds of dust from the atmosphere.how much dust will it pickup in 45 days

Answer 1

Answer: 42.9 x 10 raise to 8

Step-by-step explanation :

If in 10 days 2.6 x 10 raise to 8 pounds of dust is picked up then in 40 days 4[2.6x10raise to 8] pounds of dust is picked up. Thus in 5 days 2.6x10 raise to 8 divided by 2 or half of the dust is picked up in 5 days.

4[2.6x10 raise to 8] + 2.6x10 raise to 8 = dust collected in 45 days = 42.9 x 10 raise to 8.
