Answer:

The answer is 16π ft²

Step-by-step explanation:

What he need to do is "act" like there is a triangle in the circle, so the radius is 4, 4*2=diameter, 8, thats the length of the triangle, the height of the triangle is 4, now we find the area of the triangle, 8*4=32, 32/2=16

This is for anyone who needs it in the future

How do you solve 5x-2y= 18 and -5x+3y= -22 by solving a system of linear equations by elimination? Please add the steps in which
MaRussiya [10]
Write the 2 equations:

5x-2y=18
-5x+3y=-22

You can see that the coefficients of x are opposites, so you can add them(the 2 equations) to eliminate x.

Adding them, you get:

y=-3

So now that you know y, you can substitute the value of y into one of the original equations. Let's substitute it in the first one:

5x+6=18

Solving this, we get:

5x=12
x=12/5

x=12/5, y=-3

A one-year membership to a gym costs $725. The registration fee is $125, and the remaining amount is paid monthly. Define a vari
wel

Given :

A one-year membership to a gym costs $725.

The registration fee is $125.

To Find :

How much new members pay each month.

Solution :

Remaining fee = Total fee - Registration fee

R = $( 725 - 125 )

R = $600

Amount of fee paid monthly is :

C=\dfrac{R}{12}\\\\C = \dfrac{600}{12}\\\\C = \$50

Therefore, monthly fee is $50.

Hence, this is the required solution.

Which of the following statements are true of the hypotenuse of a right triangle? Select all that apply. A.) It is the longest s
kirza4 [7]
<span>True    A.) It is the longest side of a right triangle.
False  B.) It is one of the legs. It is opposite the right angle.
False  C.) Its length is the sum of the lengths of the other two sides.
False  D.) It forms a right angle with an adjacent side.

If option B is a single choice, then it has to be called false.

Look at option B.
B. "It is one of the legs" is false.
"It is opposite the right angle" is true.
Are you sure option B. is not two different choices, and there are really 5 choices instead of 4?

So the culture banner size has length x, width x (since it is square)
The sports banner has length x+12, width x.

The area of the sports banner is length x width = x(x+12) = x²+12x.

Now, lets look at the tiles.

- The monomial, x, a factor of the expression is the width of the sports banner.

- The binomial (x+12) is the length of the spots banner (this is given!)

- The second degree term of the expression x²+12 is x², the area of the culture banner

- The first degree term of the expression x²+12x is 12x, it represents the increase in area, since the area went from x² to x²+12x
