xeze [42]

Answer:

C.\ Perimeter = 48 * 18

Step-by-step explanation:

Given

See attachment for her sketch

Required

Which equation do not represent the perimeter

From the attached sketch:

L =18in --- Length

W =48in --- Width

Perimeter (P) is calculated as:

P = 2 * (L + W)

This gives:

P = 2 * (18 + 48) ---- This represents (A)

Open bracket

P = 2 * 18 + 2*48 ---- This represents (B)

In algebra:

2 * a means a+ a

So, the expression becomes

P = 18 + 18 +48 + 48 --- This represents (D)

<em>This implies that (C) does not represent the perimeter</em>

Write the standard form of the line that contains a slope of 1/2 and y-intercept of 3. Include your work in your final answer. T
nata0808 [166]

Answer:

2y-x=6

Step-by-step explanation:

Standard form is ax+by=c.

Slope form : y=mx+n where m is slope n-y intercept.

First we write in slope form

y=\frac{1}{2}x+3

Now we can multiply both sides by 2.

2y=x+6

Subtract for each side x

2y-x=6

A regular hexagon has a radius of 20 in. what is the approximate area of the hexagon
soldier1979 [14.2K]

Remark

You need 2 facts to solve this 

1.   The area of a hexagon is 

     A = 3*(sqrt(3) ) * a^2/2 

     Just to make this clear, I'll put it in Latex

Area = (3*\sqrt3 a^2)/ 2

2. The second fact you need to know is that the radius = the length of the side a.

Givens

r = 20 in

a = r where a is the length of the side of a hexagon.

Formula Substitute and solve.

A = 3*(sqrt(3) * a^2 ) / 2

A = 3*(sqrt(3) * 20^2) / 2

A = 3*sqrt(3) * 400 / 2

A = 3*sqrt(3) * 200

A = 3*1.7321 * 200

A = 1039 square inches.
