For this case we can make the following rule of three:
1 square mile -------------------> 4.6 * 10 ^ 4 pieces of trash
1.2 * 10 ^ 8 square miles -------> x
From here, we clear the value of x:
We have then:
x = (1.2 * 10 ^ 8) * (4.6 * 10 ^ 4)
x = 5.52 * 10 ^ 12 pieces of trash
Answer:
there are 5.52 * 10 ^ 12 pieces of trash in the earth's oceans
Answer:
r = 10
Step-by-step explanation:
Solve for r by simplifying both sides of the equation, then isolating the variable.
Answer:
I Know the answer because I am in k12 too.
The answer is 37.5%
Step-by-step explanation:
$80 - $50 = $30
$30 * 100 / $ 80 = 37.5%
answer: 37.5% of decrease.
Plug the values (x,y) into the equation and check if they satisfy the equation.
The answer is C.
Step-by-step answer:
Given:
k(x)=8x+7q...........................(1)
Evaluate: k(2q^2+3q) .......(2)
Solution:
From (1)
k(x) = 8x+7q
Substitute x=2q^2+3q into (1)
k(2q^2+3q)
= 8(2q^2+3q) + 7q
= 16q^2 + 24q + 7q
= 16q^2 + 31q
