Answer:
O✓ (0,-5)
Step-by-step explanation:
Identify the x-value in the ordered pair and plug it into the equation. When you simplify, if the y-value you get is the same as the y-value in the ordered pair, then that ordered pair is indeed a solution to the equation.
Step-by-step explanation:
Volume of a cylinder is given by cross sectional area multiplied by height hence
V=Ah
Since the cross sectional area of
Substituting the formula for A into formula for volume then
Substituting 8ft for r and 20 ft for h then
Rounded off to the nearest tenths, the volume is equivalent to
Answer:
Step-by-step explanation:
We know that
Length(l) = 1.5n + 9 ft
Width(w) = 5n - 1.5 ft
The formula for the perimeter(P) of a rectangle is:
So by substituting l and w we get :
![P= 2[(1.5n+9)+(5n-1.5)]](https://tex.z-dn.net/?f=P%3D%202%5B%281.5n%2B9%29%2B%285n-1.5%29%5D)
![P= 2[1.5n+5n+9-1.5]](https://tex.z-dn.net/?f=P%3D%202%5B1.5n%2B5n%2B9-1.5%5D)
![P= 2[6.5n+7.5]](https://tex.z-dn.net/?f=P%3D%202%5B6.5n%2B7.5%5D)
