Step-by-step explanation:
m <u>~</u><u> </u>6.9
6.9! = 4122.7
4122.7 average 4125
<u>n</u><u> </u><u>~</u><u> </u><u>8</u><u>.</u><u>9</u>
8.9! = 289867.7
289867.7 average 281600<u> </u>
We are given: Degrees Celsius and degrees Fahrenheit are related by formula
![C=\frac{5}{9} (F-32)](https://tex.z-dn.net/?f=C%3D%5Cfrac%7B5%7D%7B9%7D%20%28F-32%29)
To find : Solve formula for F in terms of C.
Solution: We have , ![C=\frac{5}{9} (F-32)](https://tex.z-dn.net/?f=C%3D%5Cfrac%7B5%7D%7B9%7D%20%28F-32%29)
First we need to get rid 9 from right denominator.
In order to get rid 9 from right denominator, we need to multiply equation both sides by 9.
![9*C=9*\frac{5}{9} (F-32)](https://tex.z-dn.net/?f=9%2AC%3D9%2A%5Cfrac%7B5%7D%7B9%7D%20%28F-32%29)
9C = 5 (F-32).
Distributing 5 on right side over (F-32), we get 5*F - 5*32 = 5F - 160.
9C = 5F - 160.
Adding 160 on both sides,
9C+160 = 5F - 160+160.
9C+160 =5F
Dividing both sides by 5, we get
(9C+160)/5 =5F/5.
![\frac{9C+160}{5}=F](https://tex.z-dn.net/?f=%5Cfrac%7B9C%2B160%7D%7B5%7D%3DF)
Splitting fraction 1/5, we get
.
Reading - 44
Sports - 55
Video games - 55
Music - 66
--------------------------
= 220
Reading = (44/220) x 100 = 20%
Sports = (55/220) x 100 = 25%
Video games -> same as sports
Music = (66/220) x 100 = 30%
20 + 25 + 25 + 30 = 100%
hope this helps :)
