Question

in 25 days the earth picks 6×10 square pounds dust from the atmosphere .how much dust will it pick up in 15 days ?? and also explain the answer

Answer 1

First, We find what is 6x10^2

6x10=60
60^2=3600.

Then you divide the 3600pounds of dust and divide it by 25 days so you can get how many pounds a single day. So:

3600/25=144

144=Pounds per day.

Finally, you multiply 144(Pounds of dust a single day) with 15 (The days)

So you get: 144x15=2160.  The earth picks up 2160 pounds of dust in 15 days.

Answer 2

Answer:

360,000,000 pound of dust in 15 days

Step-by-step explanation:

As the Earth picks 6X10^8 pounds of dust in 25 days, so it picks

pounds of dust in 1 day.

It then picks

24,000,000 X 15 = 360,000,000= 36 X 10^7 pounds in 25 days
