Final answer:
To convert 25ºC to Fahrenheit, use the formula F = 1.8C + 32º. After performing the calculation (1.8× 25) + 32, the result is 77ºF, which is an option (D).
Step-by-step explanation:
When you want to find the temperature in degrees Fahrenheit given a temperature in degrees Celsius, you can use the formula F = 1.8C + 32º. To find the temperature in Fahrenheit when C equals 25º, simply plug the value of C into the formula:
F = 1.8(25) + 32
First, multiply 1.8 by 25:
1.8 × 25 = 45
Then, add 32 to the result:
45 + 32 = 77ºF
So, when C equals 25º, the temperature in degrees Fahrenheit is 77º. This corresponds to answer choice (D).
