Answer:
B
Step-by-step explanation:
A rhombus is divided into four congruent triangles. The two given angles are complementary, meaning they add up to 90 degrees. Set up an equation:
![(4x-25)+x=90](https://tex.z-dn.net/?f=%284x-25%29%2Bx%3D90)
Take out the parentheses
Combine like terms
Add 25 to both sides so as to isolate the variable
Divide both sides by 5
This is just another way of asking "what is the volume of a sphere of 6cm"
The volume of a sphere is
![V= \frac{3}{4} \pi R^{3}](https://tex.z-dn.net/?f=V%3D%20%5Cfrac%7B3%7D%7B4%7D%20%5Cpi%20%20R%5E%7B3%7D%20%20)
The R is 3cm in this problem since the diameter is twice the radius. For a 3cm radius sphere this is 113.1cm^3
Answer:
![y = - 1x + b](https://tex.z-dn.net/?f=%20y%20%3D%20%20-%201x%20%2B%20b)
Step-by-step explanation:
The inverse of a slope is the exact opposite slope of the original. I'll show a function below where you can easily solve future problems if you need to.
![- \frac{1}{m} x](https://tex.z-dn.net/?f=%20-%20%20%5Cfrac%7B1%7D%7Bm%7D%20x)
m is the slope, so for the equation above, you simply insert the original slope, being 1, in the equation.
![- \frac{1}{1} x \\ - 1x](https://tex.z-dn.net/?f=%20-%20%20%5Cfrac%7B1%7D%7B1%7D%20x%20%5C%5C%20%20-%201x)
So the inverse slope would be -1.
