Answer:
x=11.7
Step-by-step explanation:
When every you have a straight line with a transversal, the line going through the straight line, the two angles will add up to 180.
180=10x+2+5x+3 ---> combine like terms
180=15x+5 ---> subtract 5 to the other side
175=15x ---> divide 15 to the other side
x=11.7
Answer: B
Step-by-step explanation: You make the values in the parentheses equal to zero.
(X + 3) = 0
X = -3
A is wrong because the root would be 3, not negative 3. C is wrong because 3 isn’t guaranteed to be a root. D is wrong because -3 is a real solution.
Answer:
Step-by-step explanation:
Given
diameter of the cone is ![d=23\ cm\quad [r=\frac{d}{2}=11.5\ cm]](https://tex.z-dn.net/?f=d%3D23%5C%20cm%5Cquad%20%5Br%3D%5Cfrac%7Bd%7D%7B2%7D%3D11.5%5C%20cm%5D)
The height of the cone is 
The volume of a cone is 
Insert the values
Thus, the volume of the cone is
