Answer:3/4
Step-by-step explanation:
Multiply 1/6 by 2 to get 2/12 and then add that to 7/12 and get 9/12
If you simplify that you end up with 3/4
Area of a circle = pi*r^2.
Here, A = 380.13 mi. Unfortunately, "mi" is NOT a unit of area.
So I will assume that the problem should read A = 380.13 sq. miles.
380.12 mi^2
Thus, 380.13 mi^2 = 3.14*r^2, and r^2 = ------------------- 121.057 mi^2
3.14
The radius is the sqrt of 121.057 mi^2: 11.00 miles.
The diam. is twice that, or d = 22.00 miles.
Answer:

Explanation: For a general binomial expansion,

, we know that the powers have to add up to the initial power. This means that the power of x and power of y have to add up to n. This is the binomial theorem.
To further demonstrate this, let's use:

We can easily expand this. Using Pascal's Triangle, we get:

As we progress along the expansion, we can see that in each term, the summation of each power remains constant, namely 4.
It doesn't matter what term the binomials are, because the power summation will never change.
This is why we can say that it is raised to the 12th power, and the binomial is:
(5x - 6y).
Thus, we get:
(DVD player+ TV)= 49.36+705.20= 754.56
754.56/12=62.88
She will have to pay $62.88 each time
Answer:
-3x + 5.
Step-by-step explanation:
(f + g)(x) = x + 8 - 4x - 3
= -3x + 5.
