A candle holder is in the shape of a triangular pyramid. The area of the base is 15 in2
EleoNora [17]

The volume of candle holder is 30 inches cubed.

Step-by-step explanation:

Given,

Area of base = A = 15 square inches

Height of candle holder = H = 6 inches

As the holder is in shape of triangular pyramid, therefore,

Volume of candle holder = \frac{1}{3}AH

Volume of candle holder = \frac{1}{3}*15*6

Volume of candle holder = \frac{90}{3}=30\ in^3

The volume of candle holder is 30 inches cubed.

The variable Z is directly proportional to X. When X is 15, Z has the value 45.
Alekssandra [29.7K]
Hello!

If variable Z is directly proportional to X, this means that the value of X increases a certain amount when Z increases. The same will apply to decreasing of either variable.

If Z = 45, X = 15. This means Z is 3 times as much as X.
X is currently 23. We can now figure out for Z.

Since Z is 3 times as much as X, multiply 23 by 3.
23 * 3 = 69

The value of Z is 69 when X is 23.

I hope this helps!
