P(red) = 9/(9 + 7 + 11) = 9/27 = 1/3
P(green) = 7/27
P(red or green) = 1/3 + 7/27 = 16/27
Answer:
yes they are proportional
Answer:
Where is it?
Step-by-step explanation:
For this case we have the following polynomial:

The first thing to do is to place the variables on the same side of the equation.
We have then:

We complete the square by adding the term (b / 2) ^ 2 on both sides of the equation.
We have then:

Rewriting we have:

Therefore, the solutions are:
Answer:
the solution set of the equation is:
Answer:
5. 314.16 feet squared
6. 615.75 inches squared
7. 254.47 kilometers squared
8. 380.13 yards squared
Step-by-step explanation:
A=πr^2
For 5 and 6 plug in the numbers and multiply. For 7 and 8, they give you the diameter, to find the radius, simply divide the number by 2, then plug the number into the formula.
Have a good day :)
