A piece of copper tubing is in the shape of a hexagonal prism. The area of the base of the prism is 3 square centimeters. The vo
Evgen [1.6K]

Answer: 17 cm

Step-by-step explanation:

For a regular figure where the area of the base is B, and the height is H, the volume is calculated as:

V = B*H

Here we know that the base of the prism is B = 3 cm^2, and the volume of the prism is 51 cm^3

Then:

B = 3cm^2

V = 51cm^3

If we replace those in the equation above, we get:

51 cm^3 = (3cm^2)*H

Solving this for H gives:

(51 cm^3)/(3 cm^2) = H = 17 cm

The height of the tubing is 17 cm

Plz answer!! only if you are correct. don’t answer just for points :)
Ann [662]

Answer

Step-by-step explanation:

Both 1 and 2 equel up to 90 degrees

so to find x for 1 and 2 you would simplify the equations

90 = 6x - 3

and

90= 3x - 6

simplify them and you wil get the answers you want

another way to do it is combining the two and solve.

90 = 9x - 9  

Just simplify :)

Can somebody help me pleasee????
Marina86 [1]

Answer:

C

Step-by-step explanation:

3x + 3y = -x + 5y

3x + x = 5y - 3y

4x = 2y

Divide both by 2

2x = y

(1,2) when x=1, y=2

2(1)=2 is a true statement

(2,4) when x=2, y=4

2(2)=4 is a true statement
