-The Formula for Converting Fahrenheit Temperatures to Celsius Temperatures $C = \frac { 5 } { 9 } ( F - 32 )$

question 16

Multiple Choice

Solve.
-The formula for converting Fahrenheit temperatures to Celsius temperatures is $C = \frac { 5 } { 9 } ( F - 32 )$ . Use this formula to solve the problem. In a certain city, the average temperature ranges from $- 29 ^ { \circ }$ to $10 ^ { \circ }$ Celsius. Use a compound inequality to convert these temperatures to Fahrenheit temperatures. If necessary, round to the nearest tenth of a degree.

• A) \(- 20.2 ^ { \circ } \leq \mathrm { F } \leq 50 ^ { \circ }\)
• B) \(15.9 ^ { \circ } \leq \mathrm { F } \leq 37.6 ^ { \circ }\)
• C) \(- 52.2 ^ { \circ } \leq \mathrm { F } \leq 18 ^ { \circ }\)
• D) \(- 84.2 ^ { \circ } \leq \mathrm { F } \leq - 14 ^ { \circ }\)
