Answer:

[tex]Volume = 7200in^3[/tex]

Step-by-step explanation:

Given

[tex]B = 24[/tex] --- base of the tank base

[tex]h = 20[/tex] --- height of the tank base

[tex]H = 36[/tex] --- height of the tank

Required:

Determine the volume of water needed for 6 inches below the top

First, calculate the area of the tank base.

[tex]Area = \frac{1}{2}Bh[/tex]

[tex]Area = \frac{1}{2}*24*20[/tex]

[tex]Area = 12*20[/tex]

[tex]Area = 240[/tex]

If the tank is filled 6 inches below the top, this means that the height of the water is H - 6.

So, the volume is:

[tex]Volume = Area * (H - 6)[/tex]

Substitute 240 for Area and 36 for H

[tex]Volume = 240 * (36 - 6)[/tex]

[tex]Volume = 240 * 30[/tex]

[tex]Volume = 7200in^3[/tex]

Perimeter= 4x+8 and Area= 2x+1x^2+2

Step-by-step explanation:

Answer:

x-y=5

4x+6y=120

Step-by-step explanation:

let x = # of 4-point questions

ley y = # of 6-point questions

# of 4-point questions is 5 more than # of 6-point questions

x=y+5 or x-y=5

now there's the matter of the points. Since each x is worth 4 points and each y is worth 6 points, they total number of points have to add up to 120, therefore:

4x+6y=120

The System of Equation is

x-y=5

4x+6y=120

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

let x be number of 4-point questions.

ley y be number of 6-point questions.

as, the 4-point questions is 5 more than 6-point questions

So, x=y+5

or x-y=5.................(1)

Since each x is worth 4 points and each y is worth 6 points, they total number of points is 120.

So, 4x+6y=120....................(2)

Answer:

D. 28,923

Step-by-step explanation:

We are given four numbers and are asked to find out which number is odd.

An odd number is a number that cannot be split evenly, if it is split, it will end up in either a fraction or a decimal.

Even numbers are the opposite, so which would be the answer?

This would be D. 28,923. 28,923 divided by 2 gives you a decimal. Which is 14461.5, all the other choices give you whole numbers.

hexagon because it have 6 sides

Step-by-step explanation:

it is irregular because it sides are not equal

THIS POLYGON IS IRREGULAR BECAUSE THIS IS HEXAGON AND IT IS IRREGULAR

an hexagon is a six sided irregular polygon

What is polygon?

a simple closed curve which does not interest itself made up if only line system is called a polygon

REGULAR POLYGON- polygon whose all side are of equal length and all angles are of equal measure

are called regular polygon

EX - SQUARE

IRREGULAR POLYGON- polygon which are not regular are called a regular polygon quadrilateral and Isosceles triangle is an example

Answer:

Step-by-step explanation:

There are three times as many orange cats as black and white cats,

o = 3(b + w)

two times as many black and white cats as grey cats,

b + w = 2g

three fewer gray cats than white cats,

g = w - 3

three times as many white cats as calico cats,

w = 3L

and five white cats

w = 5

There is a problem with this.

There are 5 white cats.

There are 3 times as many white cats as calico cats.

That means there are 5/3 calico cats.

How can the number of a certain type f cats be a non-whole number?

It seems that the number of white cats must be a multiple of 3, but 5 is not.

Answer:

w=10

Step-by-step explanation:

You would have to set 5w-4=46.

5w-4=46

Add 4 to both sides

5w=50

Divide both sides by 5

w=10

Answer:

W=10

Step-by-step explanation:

5w-4 and 46 are vertical angles which means they are congruent, so you set them as equal to each other and alive from there

Answer:

x = 6.4

Step-by-step explanation:

ignore the rectangle part and cut it off. You'd get a triangle with legs of 5 and 4. do the hypotenuse thing. a squared + b squared = c squared. 5 squared + 4 squared = x squared. when you solve, you get rad 14, which simplifies to 6.4
