Answer:
(A)The height of each pyramid is One-half h units.
Step-by-step explanation:
Height of the Cube = h units
Volume of the Cube 
If Base of the cube =Base of the square pyramid
Base of the square pyramid = h units
Since Volume of the Cube = Volume of Six Square Pyramids
Then:
I think it’s 1 because there’s 9 shirts left and atleast one of them has to be green
Answer:
757.35
Step-by-step explanation:
1. We assume, that the number 891 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 891 is 100%, so we can write it down as 891=100%.
4. We know, that x is 85% of the output value, so we can write it down as x=85%.
5. Now we have two simple equations:
1) 891=100%
2) x=85%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
891/x=100%/85%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 85% of 891
891/x=100/85
(891/x)*x=(100/85)*x - we multiply both sides of the equation by x
891=1.1764705882353*x - we divide both sides of the equation by (1.1764705882353) to get x
891/1.1764705882353=x
757.35=x
x=757.35
now we have:
85% of 891=757.35
