Answer:
[tex]18^{\circ}C[/tex]
Step-by-step explanation:
Given :The temperature is 64.4 degrees Fahrenheit
To Find : What is the temperature in degrees Celsius?
Solution:
The temperature is 64.4 degrees Fahrenheit
To convert in into Celsius
Formula : [tex]T(^{\circ}C) =(T(^{\circ}F)-32) \times \frac{5}{9}[/tex]
Substitute the vale
[tex]T(^{\circ}C) =(64.4-32) \times \frac{5}{9}[/tex]
[tex]T(^{\circ}C) =(32.4) \times \frac{5}{9}[/tex]
[tex]T(^{\circ}C) =18^{\circ}C[/tex]
So, Option A is true
Hence the temperature in degrees Celsius is [tex]18^{\circ}C[/tex]
