Question

If a thermometer indicates 40 degrees Celsius, what is the temperature in degrees Fahrenheit?

Answer 1

If you want to convert 40 degrees Celsius to degrees Fahrenheit, you can do it this way:
40°C * 9/5 + 32 = 104°F

The correct result is B. 104°F.

Other options:
A. 72°F = 22.2°C
C. 54°F = 12.2°C
D. 22°F = -5.56°C

Answer 2

Answer:

Option B is correct.

Temperature in degree Fahrenheit is, $104 ^{\circ}F$

Step-by-step explanation:

We will use the temperature conversion formula from  $^{\circ}C$ to   $^{\circ}F$ as follows:

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

where

F is the Fahrenheit in degree,

C is the Celsius in degree.

Given the statement: If a thermometer indicates 40 degrees Celsius.

⇒$C = 40^{\circ}$

Substitute this value in above formula to solve for F;

$F =\frac{9}{5}(40)+32$

$F =72+32$

Simplify:

F = 104 degree.

therefore, the temperature in degree Fahrenheit is, $104 ^{\circ}F$
