siniylev [52]2 years ago
5 0

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.

Brad wants to open a new savings account. He finds one that returns 3% on his investment each year.
Rufina [12.5K]

Answer:

  • final balance: A
  • initial investment: P
  • return rate: r

Step-by-step explanation:

The variable assigments can be anything you like. It is often helpful to use variables that will remind you what they stand for. Here, we have chosen A = amount (final balance); P = principal (initial investment); r = rate.

No you have to make sure to line up the decimals when subtracting them. Do not just line of the numbers, this wills get you the wrong answers. Hope this helps. If you need anything else just call for a helping hand.
