Question

Hi, what formula would i use for temperture and how do I solve?

Answer 1

SOLUTION:

To covert temperature from degree to Celsius to Fahrenheit, we make use of the formula below;

$C\text{ = }\frac{5}{9}(F\text{ - 32)}$

So we convert 20 degrees Celsius to Fahrenheit;

$\begin{gathered} C\text{ = }\frac{5}{9}\text{ (F-32)} \\ \\ 20\text{ = }\frac{5}{9}(F-32) \\ 20\text{ X 9 = }5(F-32) \\ 180\text{ = 5(F-32)} \\ \frac{180}{5}\text{ = F - 32} \\ \\ 36\text{ = F - 32} \\ F\text{ = 36 + 32} \\ F=68^0 \end{gathered}$

The equivalent Fahrenheit temperature is 68 degrees Fahrenheit.
