Is it ever the case that the temperature in degrees Fahrenheit is the same as the
1 answer:
9514 1404 393
Answer:
yes. -40°C = -40°F
Step-by-step explanation:
The relationship between the two temperature scales is ...
C = 5/9(F -32)
If we set the numerical values equal, we have ...
F = C
F = 5/9(F -32) . . . . .substitute for C
9F = 5(F -32) . . . . . multiply by 9
4F = -160 . . . . . . . . eliminate parentheses, subtract 5F
F = -40
The two temperature scales have the same value at -40°.

That's the bottom mark on the thermometer scales attached. (Unfortunately, those scales seem to be slightly misaligned. 0°C doesn't line up exactly with 32°F, either. Oops.)
