Answer:
D) 523.6 ft
Step-by-step explanation:
Use the equation for volume of a sphere
![V=\frac{4}{3}\pi r^{3}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E%7B3%7D)
Plug in 5 for the radius
![V= \frac{4}{3}\pi 5^{3}](https://tex.z-dn.net/?f=V%3D%20%5Cfrac%7B4%7D%7B3%7D%5Cpi%20%205%5E%7B3%7D)
V = 523.6 ft

Answer:
50 square units
Step-by-step explanation:
The outside square is 10 units on each side. If you fold the figure along each side of the shaded square, you find the white triangles exactly fill the shaded area. That means the shaded area is equal to the white area, so the shaded square is half the total area of 10×10 = 100 square units.
The shaded area is 50 square units.

3 - x = -16/2
3 - x = -8
-x = -8 - 3
-x = - 11
x = 11</span>
Answer:
Burger meal costs $8 and hot dog meal costs $6.
Step-by-step explanation:
To find the price per meal, write a system of equations.
Let b = cost of a burger meal and d = cost of a hot dog meal.
Write the equation 3b + 4d = 48 for the Woodsons.
Write the equation 6b + 2d = 60 for the Barkers.
Use elimination to solve the system. Begin by making the coefficients of one variable the same in both equations by multiplying 3b + 4d = 48 by 2.
2(3b + 4d = 48) ----> 6b + 8d = 96
Stack the equations and subtract.
6b + 8d = 96
- 6b + 2d = 60
------------------------
6d = 36
d = 6
Substitute d = 6 into one equation to solve for b.
3b + 4(6) = 48
3b + 24 = 48
3b = 24
b = 8
