Answer 1

The equivalent Fahrenheit temperature is 50°F.

Solution:

Given equation:

$F=(9 / 5) C+32$

C = 10°C

To find the equivalent Fahrenheit temperature of 10°C:

$F=(9 / 5) C+32$

$F=\frac{9}{5} C+32$

$F=\frac{9}{5} (10)+32$

$F=\frac{90}{5} +32$

$F=18+32$

F = 50°

Hence the equivalent Fahrenheit temperature is 50°F.

Option D is the correct answer.
