Answer:

$5 per shirt

Step-by-step explanation:

Set up a proportion: $\frac{8}{40} = \frac{1}{x}$
Cross multiply, then divide: 1 × 40 = 40, 40 ÷ 8 = 5
So, it is $5 per shirt.

I hope this helps!

Answer:

$5 per shirt

Step-by-step explanation:

Unit rate is price per one item so to find it you take the total cost and divide by number of items so in this case we have 8 shirts and together they are $40 we divide 40 by 8 and 40/8 is 5 that's how to get your answer.

What is the equation of the circle that has its center at -26,120 and passed through the origin

OlgaM077 [116]

well, first off let's check those two points, we know it's centerd at (-26 , 120) and we also know it passes through (0 , 0), so the distance between those two points is its radius

$~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{0}~,~\stackrel{y_1}{0})\qquad (\stackrel{x_2}{-26}~,~\stackrel{y_2}{120})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ \stackrel{radius}{r}=\sqrt{(~~-26 - 0~~)^2 + (~~120 - 0~~)^2} \implies r=\sqrt{(-26)^2 + (120 )^2} \\\\\\ r=\sqrt{( -26 )^2 + ( 120 )^2} \implies r=\sqrt{ 676 + 14400 } \implies r=\sqrt{ 15076 } \\\\[-0.35em] ~\dotfill$

$\textit{equation of a circle}\\\\ (x- h)^2+(y- k)^2= r^2 \hspace{5em}\stackrel{center}{(\underset{-26}{h}~~,~~\underset{120}{k})}\qquad \stackrel{radius}{\underset{\sqrt{15076}}{r}} \\\\[-0.35em] ~\dotfill\\\\ ( ~~ x - (-26) ~~ )^2 ~~ + ~~ ( ~~ y-120 ~~ )^2~~ = ~~(\sqrt{15076})^2 \\\\[-0.35em] ~\dotfill\\\\ ~\hfill (x+26)^2+(y-120)^2 = 15076~\hfill$

An art gallery displays a large painting in the center of a wall that is 24 feet ( ft wide. The painting is 10ft wide. Which of

san4es73 [151]

the complete question in the attached figure

step 1

Find the distance of the center of the wall from the left end of the wall

distance=(1/2)*24--------> 12 ft

If x is the distance from a painting edge to its corresponding end of the wall, then

|x-12| is the distance from the painting edge to the center of the wall

and

If the painting is centered, then 2|x-12| represents the width of the painting

Since the painting is 10 ft wide,

we have 2|x-12|=10

therefore

the answer is the option B

2|x-12|=10

A rectangle has an area of 8 square centimmetres and a perimeter of 12 cm. What are the width and breath?

vlada-n [284]

Let the Length be L and the Width be W

The area is 8 cm²
LW = 8

The perimeter is 12
2(L + W) = 12
L + W = 6

Solve L and W:
LW = 8 --------------- (1)
L + W = 6------------ (2)

Equation (2):
L + W = 6
L = 6 - W -------------- Sub into (1)
(6 - W) W = 8
6W - W² = 8
W² - 6W + 8 =0
(W -2 )(W - 4) = 0
W = 2 or 4

When W =2, L = 6 - 2 = 4
When W = 4, L = 6 - 4 = 2

Answer: The Width is 2 cm and the Length is 4 cm
