You are trying to find what won't be in the water because there are many combinations so you use a complement formula.
1-0.79=0.29
Use the left over percentage in an equation to determine the probability.
The exponent 6 comes from the number of locations.
It takes 45 minutes because if you do 6 divided by 2 you get 3 and then you do 3 x 15 you get 45. So 45 is your answer
x is a variable. You need to find the variable to complete the equation.
ex. x = 1
x to the power of 5 (1x5x5x5x5x5)
1*x(0)=0
= 318
And the calculator can help you on problems like this

Answer:
Area: 7850 square cm
Perimeter: 314 cm.
Step-by-step explanation:
The area is 
. With r=50, 
=2500π which is about (2500)(3.14)=7850.
The perimeter is 
which is the same as (diameter)(π). The diameter is 100, so 
which is about (100)(3.14)=314.
