P= Price
O= Original price
N= Number of days
P= O - (N * 0.02)
EXAMPLE:
O= 50
N= 1 day
P= 50 - ( 1* 0.02) = 49.98
N= 2 days
P= 50 - ( 2* 0.02) = 49.96
N= 3 days
P= 50 - ( 3* 0.02) = 49.94
N= 4 days
P= 50 - ( 4* 0.02) = 49.92
N= 5 days
P= 50 - ( 5* 0.02) = 49.90
N= 6 days
P= 50 - ( 6* 0.02) = 49.88
N= 7 days
P= 50 - ( 7* 0.02) = 49.86
We're given c to f and we want f to c:
![f= \frac 9 5 c + 32](https://tex.z-dn.net/?f=%20f%3D%20%5Cfrac%20%209%205%20c%20%2B%2032%20)
![f - 32 = \frac 9 5 c](https://tex.z-dn.net/?f=%20f%20-%2032%20%3D%20%5Cfrac%209%205%20c)
![c = \frac 5 9 (f-32)](https://tex.z-dn.net/?f=c%20%3D%20%5Cfrac%205%209%20%28f-32%29%20)
We substitute f=62
![c= \frac 5 9(62-32)= \dfrac{5(30)}{9} = 16.66666... \approx 17 \textrm{ C}](https://tex.z-dn.net/?f=%20c%3D%20%5Cfrac%205%209%2862-32%29%3D%20%5Cdfrac%7B5%2830%29%7D%7B9%7D%20%3D%2016.66666...%20%5Capprox%2017%20%5Ctextrm%7B%20C%7D)
Twelve runners because if you take three-fourths times four you will get twelve-sixteenths. and each runner runs one-sixteenth so it is twelve.
Answer:
To convert degrees to radians, multiply by π180° π 180 ° , since a full circle is 360° 360 ° or 2π 2 π radians. 225°⋅π180° 225 ° ⋅ π 180 ° radians.
