If a thermometer indicates 30 degrees celsius, what is the temperature in degrees fahrenheit?
a. 24°f
b. 17°f
c. 86°f
d. 54°f

Answer=C

The conversion formula between Celsius and Fahrenheit is:

°F=(9/5*°C)+32

Based on the information given, we know that °C=30. So we can solve for °F.

°F=(9/5*°C)+32
°F=(9/5*30)+32
°F=(54)+32
°F=86

30 Degrees Celcius is equivalent to 86 degrees Fahrenheit.

If a thermometer indicates 30 degrees Celsius, the temperature in degrees Fahrenheit is 86°F.

Boiling water measures 100 degrees in Celsius, and 212 degrees in Fahrenheit. Freezing water measure 0 degrees in Celsius, and 32 degrees in Fahrenheit. 

So, if you want to convert Celsius into Fahrenheit, you will need to:
Multiply by 180/100
Add 32

Let's convert 30 degrees Celsius into Fahrenheit.
30  180/100 = 54
54 + 32 = 86

69 i think because is the only one square
