Answer: 1/4 ounces per hour
Step-by-step explanation:
In the 3 hours that the bucket has leaked, it has lost 3/4 ounces.
The rate at which it is leaking is therefore:
= 3/4 / 3
= 3/4 * 1/3
= 3/12
= 1/4 ounces per hour
Answer:
D
Step-by-step explanation:
Use the formula for the SA of a hemisphere.
![SA=2\pi r^2](https://tex.z-dn.net/?f=SA%3D2%5Cpi%20r%5E2)
Now we can find the radius of the hemisphere, which is 15.
Then, we can square that and multiply it by 2 to get 450.
Now, let's use the formula for the Volume of a hemisphere.
![V=\frac{2\pi r^3}{3}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B2%5Cpi%20r%5E3%7D%7B3%7D)
Now we can cube 15 and multiply it by 2 to get 6750.
Then we can divide this number by 3.
2250.
So the answer is D.
You can put 10 in the equation:
-10^2 -3*10 = -100 -30 = -130
4x + x + x= 6x
180(angle on a straight line ) = 6x
180/6 =
X = 30
Angle CBD= 4x
4(30) = 120
CBD=120 degrees
