This is a combination problem. The approach to this is by using the nCr method, where n is the number of total objects and r is the number of success. For example, if you want to get 3 red out of the total 4, then that would be 4C3. That means,
4C3 = 4!/3!(4 - 3)! = 4 ways
If you want to get 2 green out of the total 6, then that would be 6C2. That means,
6C2 = 6!/2!(6-2)! = 15 ways
Therefore, there are a total of 4+15 = <em>19 ways</em>.
The answer is 15000 i took the text a while ago!
This is a simple

Pythagorean Theorem problem.
So here we go:
Imagine a right triangle with 2 legs and a hypotenuse.
The Pole is the vertical leg. The Cable is the hypotenuse. The distance on the ground between the cable and the pole is the 3rd leg.
We are trying to find the hypotenuse which is C in our Pythagorean Theorem.
Thus:

Add the squares:

Now take the square root of both sides:
*Remember that in triangles, we cannot have a negative value for the length. (If it's possible, please contact the Nobel Prize admins).

Thus:
The answer is NOT A nor B, because they're both decreasing.
D's answer shows that the graph is only increasing by 1/2, and C shows that the graph will increase at a normal rate.
The answer is <em>C</em>.
Answer:
8x +10
Step-by-step explanation:
12x + 3 − 4x + 7
Combine like terms
12x-4x +3+7
