Temperatures on the Celsius and Fahrenheit scales are related by the function \( C = \frac{5}{9}(F - 32) \), where \( C \) is the temperature in degrees Celsius and \( F \) is the temperature in degrees Fahrenheit.

What temperature on the Celsius scale is equivalent to 77 degrees Fahrenheit?

A. 15 degrees Celsius
B. 20 degrees Celsius
C. 25 degrees Celsius
D. 30 degrees Celsius

Answer :

Answer: C = 5.(77 - 32)/9

C = 5.45/9

C = 225/9

C = 25 graus.

Step-by-step explanation:

Answer:

Option C) 25 degrees Celsius

Step-by-step explanation:

C = 5(F – 32)/9

To find the equivalent scale in Fahrenheit, we substitute the value of F in the equation as 77.

Therefore:

C = 5(F – 32)/9

C = 5( 77 - 32 ) / 9

Simplify the brackets first, before opening it.

C = 5 ( 45) / 9

C = 5 * 5

C = 25 Degree Celsius

Option C is correct

Maths is fun!
