A single tree produces about 2.6 x 10^2 lb of oxygen each year.The Amazon rainforest has about 3.9 x 10^11 trees.About how many
inna [77]
So to multiply standard form we multiply the 2 numbers and the 2 indices separately.

2.6*3.9=10.14
x^{2} *  x^{11} = x^{13}

So we've got 10.14*10^{13}
However Standard form must be 1 \leq x \leq 10 therefore we need to divide that by 10 but to get the same number we add one onto the power of 10.

So the answer is:

1.014*10^{14} lbs of oxygen are produced in the rainforest each year.

Answer:

Emilia bought 28 sweets

Step-by-step explanation:

now they have 65, but before they had 65-15+10 because earlier, zakiah had ten more sweets than now and Emilia had 15 less, so basically, if you wanna calculate number of sweets they had earlier, you have to make minus from plus and in reverse too.

65-15+10=60 and now just do that simply ratio

E:Z=7:8

E+Z=7x+8x

60=15x

4=x

7x=28=Emilia

8x=32=Zakiah

Accuracy test:

(28+15)+(32-10)=65

28 is 4•7 and 32 is 4•8
