Question

help please? C=
5
9
(F−32)

The equation above shows how temperature F, measured in degrees Fahrenheit, relates to a temperature C, measured in degrees Celsius. Based on the equation, which of the following must be true?

A temperature increase of 1 degree Fahrenheit is equivalent to a temperature increase of
5
9
degree Celsius.
A temperature increase of 1 degree Celsius is equivalent to a temperature increase of 1.8 degrees Fahrenheit.
A temperature increase of
5
9
degree Fahrenheit is equivalent to a temperature increase of 1 degree Celsius.
A) I only
B) II only
C) III only
D) I and II only

Answer 3

Let's play with a few numbers
\(C=\frac{5}{9}(F-32)\)

If we plug in F = 41 into the formula:
\(C=\frac{5}{9}(F-32)=\frac{5}{9}(41-32)=\frac{5}{9}(9)=5\)

Let's test out your options:
If we increase F by 1, the new F = 42
\(C=\frac{5}{9}(F-32)=\frac{5}{9}(42-32)=\frac{5}{9}(10)=5.555...\)

The temperature increased by 0.55555 = 5/9 when we increased F by 1

does that make your option I true?
