If the formula for coverting degrees Fahrenheit to degrees Celsius is C = 59(F−32)\frac{5}{9}(F-32), What is the value of F when C is 30?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. 86

Given:

 C = 59(F−32)\frac{5}{9}(F-32), temperature in celsius = 30

Calculations:

⇒ 30 = 5/9(F - 32)

⇒ 30 × 9 = 5F - 160

⇒ 270 = 5F - 160

⇒ F = 54 + 32

⇒ F = 86
