#### Answer

$86^{\circ}~F$

#### Work Step by Step

$F = \frac{9}{5}C+32$
We can use this formula to convert from Celsius to Fahrenheit. It is given in the question that $C = 30$ since the temperature on the Celsius scale is $30^{\circ}~C$.
$F = \frac{9}{5}C+32$
$F = \frac{9}{5}(30)+32$
$F = 54+32$
$F = 86$
The temperature on the Fahrenheit scale is $86^{\circ}~F$
