Answer: a. 14% decrease or 86% of the whole
B. 137.5% increase
Step-by-step explanation:
A. Divide new price by old price and you get .86, change that to a percent by multiplying by 100. That equals 86%, the percent of change would be the difference of 100% to 86%, which is 14%
B. Use above explanation but don’t find the difference. 77/56= 1.375, 1.375*100=137.5
Answer:
120 degrees.
Step-by-step explanation:
If it is a regular 6 sided figure then each interior angle is 180 - (360/6)
= 120 DEGREES.
Answer:
14, 96,84
Step-by-step explanation:
8n - 16 + 6n = 180 {Supplementary angles}
<u>8n + 6n</u> -16 = 180
Combine like terms
14n - 16 = 180
Add 16 to both sides
14n = 180 + 16
14n = 196
Divide both sides by 14
n = 196/14
n = 14
8n - 16 = 8*14 - 16 = 112 - 16 = 96
6n = 6 *14 = 84
