Can anyone help me with this?
siniylev [52]

Answer:

1.  280/11

2. 1700/11

3. 280/11

4. 3600

5. 360

Step-by-step explanation:

Let n = sides of a regular polygon

For these problems, n = 22 because there are 22 sides.

I am going to write the formulas needed for each question below.

  1. 360/n
  2. 180 - 360/n
  3. 360/n
  4. 180(n-2)
  5. 360 (isn't affected by n)

To solve, just plug in N with 22.

These formulas are very easy to prove and I recommend if you have time try to prove these.

Step-by-step explanation:

Original Population = 5893

Expected Population = 5218

% Decrease = Original Population - Expected Population / Original population

% Decrease = (5893 - 5218 ) / 5893

% Decrease = 675/5893

% Decrease = 0.11454268

% Decrease = 11.454268%

% Decrease = 11.45% approximately.
