What process do you use to find the percent change of a quantity?
Sever21 [200]
<span><u><em>First, we need to get the amount of change:</em></u>
The amount of change can either be an increase or a decrease.
It can be calculated as follows:
amount of change = </span>\frac{"new"value - "old"value}{"old" value}
<span>
If the amount of change is positive, then it is an increase
If the amount of change is negative, then it is a decrease

<u><em>Then, we need to convert this amount into a percentage:</em></u>
Changing the amount into a percentage can simply be done by multiplying this amount by 100
This means that:
% of change = amount of change * 100

<u><em>Combining the two steps:</em></u>
% of change = </span>\frac{"new"value - "old"value}{"old" value}<span> * 100

<u>Examples:</u>
The original price of a certain product was $10. It then became $12. Find the % of increase.
% of change = </span>\frac{12-10}{10} * 100<span> = 20%
This means that the price increased by 20%

The temperature decreased from 25 degrees to 20 degrees. Find the percentage of decrease.
% of decrease = </span>\frac{20-25}{25} * 100<span> = -20%
This means that the temperature decreased by 20%

Hope this helps :)</span>

Step-by-step explanation:

<u>Sum of the interior angles of a regular polygon:</u>

  • S(n) = 180°(n - 2), where n- number of sides
<h3>Exercise 4</h3>

<u>Pentagon has sum of angles:</u>

  • S(5) = 180°(5 - 2) = 540°

<u>Sum the given angles and find x:</u>

  • x° + 122° + 100° + 90° + 144° = 540°
  • x° + 456° = 540°
  • x° = 540° - 456°
  • x° = 84°
<h3>Exercise 5</h3>

<u>Hexagon has sum of angles:</u>

  • S(6) = 180°(6 - 2) = 720°

<u>Sum the given angles and find x:</u>

  • x° + 110° + 160° + 105° + 105° + 115° = 720°
  • x° + 595° = 720°
  • x° = 720° - 595°
  • x° = 125°
