The square is shown with a side length of 8 inches.

The area of a square is s^2, which can also be written as s x s, where a is the length of the side.

Area of the square would be 8 x 8 = 64 square inches.

The area of a circle is pi x r^2, where r is the radius. R is given as 3 inches.

The area of the circle is 3.14 x 3^2 = 28.26 square inches.

The shaded area is the square minus the circle.

The shaded area = 64 - 28.26 = 25.74 square inches.

The answer is 25.74 square inches.

Look at my explanation to know the answer clearly.

So, we're supposed to find the area of the shaded part.

In the problem, the shaded part is the square, and the side is 8 in.

Let's apply this formula, A = L · W or A². So, we can multiply the Length and Width to get the area.

The length is 8.

Since we don't have a width, we can use A². We can find 8 to the 2nd power to get the answer.

8 to the 2nd power is 64. How?

1. Break the exponent down.

8² ⇒ 8 × 8

2. Solve.

8 × 8 = 64

Hence, 64 is the answer. Hence, 64 is the answer. Now, we'll need to find the circumference of the circle.

The formula for that is 2 π r²

The radius is 3 in, so let's multiply 2 by 3² by 3.14.

3² × 3.14 = 28.26

Lastly, subtract 64 by 28.26.

64 - 28.25 = 25.74

Hence, your final answer is 25.74in.

At a restaurant, three salads, two sandwiches, and one drink cost $17.75. One salad, one sandwich, and three drinks cost $10.75.
Leno4ka [110]

Answer:

A salad costs $2.50

A sandwich costs $4.50

A drink costs $1.25

Step-by-step explanation:

Let x represent the salad, y represent the sandwich, and z represent the drink.

Since three salads, two sandwiches, and one drink cost $17.75:

3x + 2y + z = 17.75  (1)

Since one salad, one sandwich, and three drinks cost $10.75:

x + y + 3z = 10.75  (2)

Since a salad costs twice as much as a drink:

x = 2z  (3)

Multiply the equation 2 by -2 then, sum the equation 1 and equation 2:

-2x - 2y - 6z = -21.50

3x + 2y + z = 17.75

→ x - 5z = -3.75

Replace the x with 2z using equation 3:

2z - 5z = -3.75

-3z = -3.75

z = 1.25

x = 2z → x = 2.50

x + y + 3z = 10.75 → 2.50 + y + 3.75 = 10.75 → y + 6.25 = 10.75 → y = 4.50

Find the value of x. Show work if you can
vova2212 [387]

Answer:

Step-by-step explanation:

number of side = n =7

Sum of all the angles of  given polygon = (n -2)*180 = 5 *180 = 900

x + 140 +133 +145 + 117 + 119 + 125 = 900

                                             x +  779 = 900

                                                    x     = 900 - 779

x = 121

75% OFF!
ICE Princess25 [194]
$676.

If the sale price of the coat is $169, you are looking for the original price. I like to think about it in the sense that if an item is 75% off, you are paying 25% of the original amount. Using that logic, in order to determine the sale price you would use the equation

Original price * 25% = $169

To solve for the original price:

Original price = $169/.25 = $676.
