Express your answer using two significant figures.

Answer 1

Hey Amy,

 

 

So, you will use 1st equation or formula:

 

C = 5/9  (F - 32)   Highest

 

C = (5/9) (118 - 32) = (5/9) (86) = 430/9 = 47.7777778 = 47.8 C = 48 C

 

 

C = 5/9 (F - 32)    Lowest

 

C = 5/9 (17 - 32) = (5/9) (-15) = -75/9 = -8.3333333 = -8.3 C

 

Good luck to you
