Question

A single tree produces about 2.6 × 10² lb of oxygen each year. The Amazon rainforest has about 3.9 X 10^11 trees.

About how many pounds of oxygen are produced in the rainforest each day ?

Enter your answer in the blank
2.8 × 10 ^blank lb

Please remember these are scientific notations no exponents.

Answer 1

`(2.6*10^2) * (3.9*10^(11)) = 1.014*10^(14)`


`1.014*10^(14)` <---How much is produced by all the trees in a year.
They want how much each day so divide by 365



`(1.014*10^(14))/(365) = 2.77808*10^(11)`

`2.77808*10^(11)` <---answer per day
