The sum of the internal angles is 18*180=3240
3240\20=162 degrees.

There are 360 degrees so divide 360 by 20 and get 18 degrees

A fashion designer makes and sells hats. The material for each hat cost $5.50. The Hats sell for $12.50 each. The designer spend

labwork [276]

The designer must sell 200 hats for breaking even.

Step-by-step explanation:

Given,

Cost for material for each hat = $5.50

Selling price of each hat = $12.50

Cost spend on advertising = $1400

Let,

x represents the number of hats.

Revenue = 12.50x

Costs = 5.50x+1400

For breaking even,

Revenue = Cost

$12.50x=5.50x+1400\\12.50x-5.50x=1400\\7x=1400$

Dividing both sides by 7

$\frac{7x}{7}=\frac{1400}{7}\\x=200$

The designer must sell 200 hats for breaking even.

Point E has coordinates (-11, 7), and point F has coordinates (-5, 1). To the nearest unit, what is the distance between the two

Zigmanuir [339]

Answer:

8 units

Step-by-step explanation:

We can use the distance formula. Recall the distance formula:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Let (-11,7) be $x_1$ and $y_1$ , and (-5,1) be $x_2$ and $y_2$

Plug in the numbers:

$d=\sqrt{(-5-(-11))^2+(1-7)^2$

$d=\sqrt{6^2+(-6)^2}$

$d=\sqrt{36+36}=\sqrt{72}=6\sqrt2\approx8$
