Answer:

x = − 3 , y = − 4

Step-by-step explanation:

Write both equations in standard form

Make the coefficients of one variable opposites

Add the equations resulting from Step 2 to eliminate one variable.

Solve for the remaining variable

Substitute the solution from Step 4 into one of the original equations

Write the solution as an ordered pair

(x + 4) divided by 3

(5 + 4) divided by 3

9 divided by 3

Step-by-step explanation:

now, we're making the assumption that the front and back of the tent are trapezoidal, Check the picture below.

[tex]\textit{area of a trapezoid}\\\\ A=\cfrac{h(a+b)}{2}~~ \begin{cases} h=height\\ a,b=\stackrel{parallel~sides}{bases}\\[-0.5em] \hrulefill\\ h=32\\ a=23\\ b=36.5 \end{cases}\implies \begin{array}{llll} A=\cfrac{32(23+36.5)}{2}\implies A=952 \\\\\\ \stackrel{\textit{twice that much}}{2A=1904} \end{array}[/tex]

The fabric that used to make the front and back of the play tent is 1368.5 square inches.

An open, flat object with four straight sides and one set of parallel sides is referred to as a trapezoid or trapezium. A trapezium's non-parallel sides are referred to as the legs, while its parallel sides are referred to as the bases.

Given:

A play tent is shown.

The height of the tent is 32 inches.

The sides of the trapezoidal tent are 23 inches and 36.5 inches.

The area of the trapezoid:

Use formula,

A = h (a+b)/2,

where a and b are the sides of the trapezoid.

A = 32(23+36.5)/2

A = 1368.5/2

A = 684.25 square inches.

2A = 1368.5 square inches.

Therefore, 1368.5 square inches of fabric are required.

I believe you just find the median

Answer:

1. 14476.46

2. 25333.8

3. 19142.66

Step-by-step explanation:

Ok lets take this slow...

First, read the directions; they want you to find how much water the barrles will hold, also meaning how much space is inside the barrel? This can be a hint to find for the area of the barrles.

The formula for a cyliner is: A=2πrh+2πr^2

You already have the information to solve the formula so all you have to do is plug the amounts in, whitch would look like this.

A= 2(3.14) (72) + 2(3.14) (24) ^2

    72 * 3.14           24 * 3.14

A= 2 (226.08)   +    2(75.36)^2

       452.16   +  2 (5679.1296)

       452.16   +     11358.2592

A≈ 14476.46

You would do the same for barel B and get: 25333.8

now subtract Barral A by Barral B to find the diffrence

144476.46 - 25333.8

The diffrent of barrle A and B is 19142.66

Step-by-step explanation:

The area of the larger rectangle is \begin{align*}8(16)=128 \ \mathrm{units}^2\end{align*} and the area of the smaller rectangle is \begin{align*}5(10)=50 \ \mathrm{units}^2.\end{align*} If we compare the areas in a ratio, it is \begin{align*}50:128 \ = \ 25:64 \ = \ 5^2:8^2.\end{align*}
