Answer:
I think the answer is 80?
Step-by-step explanation:
Answer:
.
Step-by-step explanation:
We have been given that a sphere has a radius of 8 centimeters. A second sphere has a radius of 2 centimeters. We are asked to find the difference of the volumes of the spheres.
We will use volume formula of sphere to solve our given problem.
, where r is radius of sphere.
The difference of volumes would be volume of larger sphere minus volume of smaller sphere.





Therefore, the difference between volumes of the spheres is
.
The height is always measured perpendicular to the horizontal surface on which the pyramid rests, whereas the slant height is measured perpendicular to one edge of the base to the vertex, and, as we would say, appears to be slanted.
Answer:
4.5 hours
Step-by-step explanation:
So, let's write a function p(x) which represents the total cost.
Let's let x represent the amount of hours.
The cost of a piece is a constant 10.
And there is a $8 fee per hour. In other words:

We spent a total of $46.
So, substitute in 46 for p(x) and solve for x:

Subtract 10 from both sides:

Divide both sides by 8:

Reduce:

So, we spent about 4.5 hours.
Answer:
1 1/4
Step-by-step explanation:
You are multiplying a fraction by a mixed number so you have to turn the mixed number into an improper fraction.
2 1/2 -- to do this you have to multiply the denominator by the whole number, then add the numerator.
2*2= 4 4+1=5
2 1/2 = 5/2
Then, you multiply normally
1/2 x 5/2 = 5/4
5/4= 1 1/4
So, you answer would be 1 1/4
