You will need to use FOIL for this, or distribute.

So you will multiply -7y and 5y, then -7y and 3
Multiply 2 and 5y, then 2 and 3
You will get: -35y²-21+10y+6

Combine like terms:
-35y²+10y-15

There you go!

A rectangular prism measures 225 inches by 315 inches by 2 inches. How many cubes with edge length 15 inch fit in the prism? Sho

Mandarinka [93]

Answer:

34 Cubes

Step-by-step explanation:

<u>Step 1: </u>Find the Volume of the Rectangular Prism

The dimensions of the rectangular prism are: 225 inches by 315 inches by 2 inches.

Volume of the Rectangular Prism = 225*315*2=141750 Cubic Inches

<u>Step 2:</u> Find the Volume of the Cube

Edge length of the cube, s=15 Inch

Volume of a Cube = $s^3$

Volume= $15^3$ =3375 Cubic Inches

<u>Step 3: </u>Determine how many cubes fit in the prism

To find out how many cubes fit in the rectangular prism, divide the volume of the rectangular prism by the volume of the cube.

Number of Cubes =Volume of the Rectangular Prism ÷ Volume of Cube

=141750 ÷ 3375

=34

34 Cubes will fit in the rectangular prism.

Chiletso just got a new cylindrical fish tank, which he plans to stock with a variety of african cichlids.

Anit [1.1K]

The maximum number of African cichlids which can put by Chiletso in this cylindrical fish tank is 19.

<h3>What is of volume of cylinder?</h3>

Volume of cylinder is the amount of quantity, which is obtained by it in the 3 dimensional space.

The volume of the cylinder can be given as,

V=(πd^2h)4

Here, (d) is the diameter of the base of the cylinder and (h) is the height of the cylinder.

The height of tank is 30 inches and the length of the diameter of the base is 27.5 inches. Thus, the volume of it is,

V=[π(27.5)²(30)] /4

V=17818.72 cubic inches.

One us gallon is equal to approximately 231 cubic inches. Thus, the volume in gallon is,

V=17818.72/231

V=77.12 gallons.

A good rule of thumb is to have about 3 inches of fish per 2 gallons of water. The number of 6 inches cichlids the can put in 77.12 gallons tank is,

V=(77.12 x 3)/(6 x 2)

V=19.28

Thus, the maximum number of African cichlids which can put by Chiletso in this cylindrical fish tank is 19.
