Answer:
[tex]37.\bar{2}\textdegree C[/tex]
Step-by-step explanation:
The formula for converting °F to °C is:
[tex](\textdegree F -32) \frac{5}{9}=\textdegree C[/tex]
We are given the temperature of 99°F.
=====================================
[tex](99\textdegree F -32) \frac{5}{9}=\textdegree C\\\rule{150}{0.5}\\(67) \frac{5}{9}= \textdegree C\\\\\boxed{37.\bar{2} = \textdegree C}[/tex]
=====================================
Diane's temperature in Celsius is 37.22...°C.
The 2 is recurring.
=====================================
Hope this helps!
