Answer:
Amie should have multiplied 54 by 2/3
Step-by-step explanation:
The formula of the volume of a sphere is given by
, where r is the radius of the sphere.
to find the volume of the sphere, we must find 
We know that the formula of a cylinder of height h and radius r is given by

So 
We know that the sphere and the cylinder have the same height. Recall that the height of the sphere of radius r, is the diameter of a circle that passes through the heighest and lowest points of the sphere. Then, h=2r. This means that

From here, we know that
.
So the volume of the sphere is
.
So Amie should have multiplied 54 by 2/3.
Let x be the time it takes Elias and Niko to polish the silver working together. If Elias works alone, he could polish all the silver himself in 40 minutes. Then, in 1 minute, he will make
of the total work. If the same analysis is applied Niko, in 1 minute, will make
of the total work.
Working together Elias and Niko will need x minutes to make all the work. Then, in 1 minute, they will make
of the total work. So, the fraction of the total work they make in 1 minute is given by this equation:

Answer:
F(2)=8 and G(2)=4
Step-by-step explanation:
10 times as many as one hundred means that you are going to repeat 100 for 10 times. In other words, multiply 100 by 10.
So 10 times as many as 100 = 10 x 100 = 1000
This is the thousands blank.
