a prism and a pyramid are side by side. they have the same height and same base are. the volume of the prism would be ? times the volume of the pyramid?

Answers

Answer:

The volume of the prism is 3 times the volume of the cone

Step-by-step explanation:

step 1

we know that

The area of the prism is given by the formula

$V_p=Bh$ ----> equation A

where

B is the area of the circular base

h is the height of the prism

step 2

The area of the cone is given by the formula

$V_c=(1)/(3) Bh$ ----> equation B

where

B is the area of the circular base

h is the height of the cone

In this problem we have that they have the same height and same base area

substitute equation A in equation B

$V_c=(1)/(3) V_p$

solve for V_p

$V_p=3V_c$

therefore

The volume of the prism is 3 times the volume of the cone

PLEASE HELP ME!! This assignment is already late!If d + 5 >= (greater than or equal to) 17, complete each inequality.

d >= ?

d + ? >= 20

d - 5 >= ?

Answers

d + 5 >= 17
We can subtract 5 from each side:
d >= 12
To get 20 on the right, we have to add 8 to each side (20-12=8).

d + 8 >= 20

To get d - 5 from the first expression (d + 5 >= 17) we have to subtract ten from each side (5-10=-5) and we get:

d - 5 >= 7
