Answer:

C = 50.24

A = 7,925.540864 (Round to whatever you want)

Step-by-step explanation:

c = 2πr

c = 2(3.14)(8)

c= 50.24

A = πr^2

A = (3.14)(50.24)^2

A = 7,925.540864

Answer: circumference = 50.24

Area = 200.96

Step-by-step explanation:

The circumference of a circle is same as its perimeter.

The formula for determining the perimeter of a circle is expressed as

Perimeter = 2πr

Where

r represents the radius of the circle.

π is a constant whose value is 3.14

From the diagram

r = 8

Therefore,

Circumference = 2 × 3.14 × 8 = 50.24

The formula for determining the area of a circle is

Area = πr²

Area = 3.14 × 8² = 200.96

They are based on SSS. They have the middle side which they share and is equal. And those other two lines also make those sides equal, so all sides are equal and they’re congruent

7 line tshirt company manufactures t-shirts and sells them online.The company has a model where the cost C, in dollars to make x

bonufazy [111]

Answer:

The company must sell at least 2 shirts to break even.

Step-by-step explanation:

Cost:

The cost is given by the following equation:

$C = \frac{40}{30x+20} + 20 = \frac{4x}{3} + 20$

Revenue:

The revenue is given by the following equation:

$R = 15x$

How many t shirts must the company sell to break even?

Breakeven point is when the revenue is the same as the costs. So

$\frac{4x}{3} + 20 = 15x$

$15x - \frac{4x}{3} = 20$

$\frac{45x}{3} - \frac{4x}{3} = 20$

Multiplying everything by 3

$45x - 4x = 60$

$41x = 60$

$x = \frac{60}{41} = 1,...$

Since you cant make a decimal value of shirts

The company must sell at least 2 shirts to break even.

RSM HOMEWORK HELP!!!

Gnesinka [82]

Answer:

Step-by-step explanation:

∠CAB = 33 {alternate interior angles}

5x = 33 + 2x { exterior angle equals sum of opposite interior angles}

5x - 2x = 33

3x = 33

x = 33/3

x = 11

∠B = 2x = 2* 11 = 22

∠ECB = 5x = 5*11 = 55

(2x -2)^-3<br>can anyone help me with this?

zzz [600]

Answer: See below

Step-by-step explanation:

When you see that something is to the power of a negative number, it is another way of saying 1 over.

$(2x-2)^-^3=\frac{1}{(2x-2)^3} =\frac{1}{(2x-2)(4x^2-8x+4)} =\frac{1}{8x^3-8x^2+8x-8}$
