The formula for converting Fahrenheit temperature, F, to Celsius temperature, C, is C=(5/9)(F-32).

Question

If Celsius temperature ranges from 15 to 35 degrees, inclusive, what is the range for the Fahrenheit temperature? Use interval notation to express this range.

Answer 1

Hello, thank you for taking the time to post your question!

You just want to convert each of these values over using the formula in order to find the possible range of values!

C = 5/9(F – 32) means that

9/5C = F – 32

F = 9/5C + 32

Plugging in C = 15 yields

F = 9/5(15) + 32 = 27 + 32 = 59 degrees

Plugging in C = 35 yields

F = 9/5(35) + 32

F = 63 + 32 = 95 degrees

So the range of values in degrees Fahrenheit would be [59, 95] degrees

I hope that helps get you moving in the right direction! Feel free to reach out if you have any additional questions beyond that :)

Answer 2

Hey Taylor,

 

Every 1.8 degrees F is 1 degree C.  And always start at 0C = 32F

So, basically after you put value for C, add 32 afterwards.

 

F = 1.8C + 32

 

From that fact, 15 C = 59 F   &   35 C = 85 F

 

15 < C < 35   --->   59 < F < 85

 

C = [15 , 35]   --->   F = [59 , 85]
