A single tree produces about 2.6 × 102 lb of oxygen each year. The Amazon rainforest has about 3.9 × 1011 trees. About how many pounds of oxygen are produced in the rainforest each day ?
@Walkerman15
this is about the 5th time doing this problem.
ratio and conversion of units
1 tree = 2.6 × 10^2 lbs you have 3.9 × 10^11 times 1 tree so 2.6* 10^2 * 2.9 * 10^11 lbs of oxygen for the year 365 days in one year to get amount for 1 day divide by 365 keep the balance what you do to one side of an equation do to the other write your answer in scientific notation form a * 10^n where a is between 0 and 10 and n is an integer
you can shift the number 6 to get the symbol for exponent
note that you could find for one day first then multiply by the number of trees. you will get the same result.
do you have any questions?
no thank you i understand now
