Answer:
7 hours
Step-by-step explanation:
We are given that
At sunset, the temperature=-5 degrees Fahrenheit
Each hour, temperature falling=2degrees Fahrenheit
We have to find time taken to reach the temperature -19° F.
Let x be the time time taken to reach the temperature -19° F
According to question
![-5+x(-2)=-19](https://tex.z-dn.net/?f=-5%2Bx%28-2%29%3D-19)
Where we taking 2 negative because temperature decreases.
![-5-2x=-19](https://tex.z-dn.net/?f=-5-2x%3D-19)
![-5+19=2x](https://tex.z-dn.net/?f=-5%2B19%3D2x)
![14=2x](https://tex.z-dn.net/?f=14%3D2x)
![x=\frac{14}{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B14%7D%7B2%7D)
![x=7](https://tex.z-dn.net/?f=x%3D7)
Hence, it will take 7 hours for the temperature to reach -19° F.
(9/10)x3 feet
= (9/10)x36 inches
= 32.4 inches
Answer:
Step-by-step explanation:
Let yesterday's price be x
Discount percentage = 36%
Sale price = $ 560
(100-36)% of x = 560
64 % *x = 560
![\frac{64}{100}*x=560\\\\x=560*\frac{100}{64}\\\\x=875](https://tex.z-dn.net/?f=%5Cfrac%7B64%7D%7B100%7D%2Ax%3D560%5C%5C%5C%5Cx%3D560%2A%5Cfrac%7B100%7D%7B64%7D%5C%5C%5C%5Cx%3D875)
Yesterday's price = $ 875
