I'm tentatively changing my answer to say this kind of relies on practical knowledge of how stores tend to operate. If 20 coupons are given out, the store has sold all 500 shirts, arguably at a loss to the retailer. They have to have more shirts in stock to be sold at full price because, well, that's how they make money. It's more likely that such a store would carry more than just 500 shirts at the start of each day, so A is (probably) wrong.

a circular native american dwlelling has a diameter of 24 feet. how much are inside the home? use 3.14 for { } (pi)

Marizza181 [45]

Answer :

$A = 452.16 \: {ft}^{2}$

step-by-step explanation:

From the question,

the diameter:

$d = 24 \: ft$

The radius :

$r = \frac{diameter}{2}= \frac{24}{2}=12 \: ft$

$\pi = 3.14$

Area of a circle is given as

$A = \pi {r}^{2}$

By substitution,

$A = 3.14( {12}^{2} )$

$\implies \: A = 3.14 \times 144$

$\implies \: A = 452.16 \: {ft}^{2}$

Hence the area of the home is

$A = 452.16 \: {ft}^{2}$

Solve, using the substitution method.

inna [77]

Y - 2x = 8 . . . . (1)
16 + 4x = 2y . . (2)

From (1), y = 2x + 8 . . . (3)

Putting (3) into (2) gives
16 + 4x = 2(2x + 8) = 4x + 16
0 = 0

Therefore, there are infinite number of solutions.

What is the sum of 9c+(8+3c)?

mixas84 [53]

<span>9c+(8+3c)
9c+8+3c (collect like terms)

9c+3c+8
12c+8

12c+8 is the answer.
im not sure if your teacher also wants the answer to be in simplest form so im going to do that below as well:

12c+8 (4*3=12 and 4*2=8. you can take out a 4 from those 2 numbers)

4(3c+2) (this is the simplest form of </span>9c+(8+3c)<span>)

</span>

The company charges $5 per sq ft, AND has a minimum charge of 3 sq ft per order (meaning if a customer orders something SMALLER

Sindrei [870]

Answer:

15 dollars

Step-by-step explanation:

12 inches = 1 ft

so 12 inch by 12 inches is 1 ft * 1 ft

1 ft* 1 ft

1 ft^2

This is smaller than 3 ft^2 so they will get charged for 3 ft^2

3 ft^2 = 3 ft^2 * $5 / ft^2 = 15 dollars
