The answer is 38, because if you take away the 15 he bought afterwards (34-15) you get 19, and then since he sold half his collection you would double that (19×2) and that's 38.

<u>Given</u>:

The given figure is a square pyramid.

The side length of the base of the pyramid is 6.6 feet.

The height of the pyramid is 12.672 feet.

We need to determine the volume of the pyramid.

<u>Area of the base:</u>

The area of the base can be determined using the formula,

A=a^2

where a is the side length of the base.

Substituting a = 6.6, we get;

A=6.6^2

A=43.56 \ ft^2

Thus, the area of the base is 43.56 square feet.

<u>Volume of the pyramid:</u>

The volume of the pyramid can be determined using the formula,

V=\frac{1}{3}Ah

where A is the area of the base and h is the height of the pyramid.

Substituting A = 43.56 and h = 12.672, we get;

V=\frac{1}{3}(43.56)(12.672)

V=184 \ ft^3

Thus, the volume of the pyramid is 184 cubic feet.

One cylinder has a volume that is 8 Centimeters cubed less than StartFraction 7 over 8 EndFraction of the volume of a second cyl
il63 [147K]

Answer:

216= 7/8 x L -8

Step-by-step explanation:

Given that,

One cylinder has a volume that is 8cm less than 7/8 of the volume of a second cylinder

The first cylinder’s volume is 216 centimeter cubed

From given,

Let "x" be the volume of second cylinder

Therefore,

Volume of first cylinder = 7/8 of the volume of a second cylinder - 8

Thus the volume of second cylinder is 256 centimeter cubed

<h3>I'll teach you how to solve f(x)=0x63 - 52x – 96​</h3>

----------------------------------------------------------

f(x)=0x^3 - 52x – 96​

Apply rule:

0 * a= 0

0-52x-96

Group like terms:

-52x+0-96

Add/subtract the numbers:

0-96= -96

-52x-96

Your Answer Is -52x-96
