<u>Step 1: Define</u>

We are given a 5-sided polygon (irregular pentagon)

n = 5

<u>Step 2: Find Sum</u>

  1. Substitute in <em>n</em> [Sum of Angles]:                                                                    180(5 - 2)°
  2. (Parenthesis) Subtract:                                                                                   180(3)°

Answer: 540

Step-by-step explanation:

{(n - 2) * 180}

This is the formula for the sum of interior angles with side lengths n. Counting the sides we have 5 sides.

(5 - 2) * 180 = 540

What is the circumference of the following circle?<br> units<br> R=1
lesantik [10]

Answer:

6.28 or 157/25

Step-by-step explanation:

Firstly, you find the formula for the circumference of a circle which is C= PI ( diameter)

So since the radius is 1 you multiply it by 2 and get 2 so then you multiply 2 by 3.14 (pi) and get 6.28

I hope this helped!!!

c = \pi(d)

3m - (m^2 + n); if m = 2 and n 19
deff fn [24]

Answer:

- ( 17 )

Step-by-step explanation:

m = 2

n = 19

m^2

= 2^2

= 2 x 2

= 4

3m

= 3 x 2

= 6

3m - ( m^2 + n )

= 3m - ( m^2 + n )

= 6 - ( 4 + 19 )

= 6 - 23

= - ( 17 )

Two important ingredients for baking bread are yeast and flour. To make a loaf of bread of at most 30 servings, maintain a yeast
IceJOKER [234]

Answer:

If 0.25 oz of yeast is used, then 50oz of flour is needed.

It would require 0.5 oz of yeast for 90 oz the flour.

Step-by-step explanation:

We know that the proportion of yeast (y) and flour (f) is 1: 200 when a maximum of 30 servings of bread is made. This is:

\frac{y}{f} = \frac{1}{200}

So if we use 0.25 oz of yeast:

y = 0.25\\\\y = (f)\frac{1}{200}\\\\0.25 = (f)\frac{1}{200}\\\\0.25 * 200 = f\\\\f = 50\ oz

if 0.25 oz of yeast is used, then 50oz of flour is needed.

If you make 60 servings of bread with 90 oz. Of flour, then you should keep the following ratio:

\frac{y}{f} =\frac{1}{180}

So, if we use f = 90 0z of flour:

f = 90\ oz\\\\f = 180y\\\\90 = 180y\\\\y = \frac{90}{180}\\\\y = 0.5\ oz

It would require 0.5 oz of yeast.

What is the equation of the line perpendicular to y = -4x + 3 that goes through (8, -3)?
maks197457 [2]
Perpendicular slope: opposite and reciprocal
-4 opposite and reciprocal = 1/4
Y = 1/4x + b
Plug in point
-3 = 1/4(8) + b
-3 = 2 + b, b = -5
Solution: y = 1/4x - 5
