45. What temperature in Fahrenheit is 50 degrees Celsius? (Enter a numeric value only. If rounding is necessary, round to the nearest whole number.)
Answer: B
50 degrees Celsius is 122°F.
To convert 50 degrees Celsius to Fahrenheit, you can use the formula F = (C × 9/5) + 32. Applying this formula yields 122 degrees Fahrenheit.
A) 150°F
This option is incorrect because 150°F is significantly higher than the calculated value for 50 degrees Celsius. The conversion formula clearly indicates that 50°C results in a much lower Fahrenheit value.
B) 122°F
This is the correct answer. Using the conversion formula, 50 degrees Celsius converts precisely to 122 degrees Fahrenheit, confirming that this option is accurate.
C) 120°F
Option C is incorrect as 120°F is slightly lower than the actual conversion result. The conversion calculation shows that 50 degrees Celsius is approximately 122°F, not 120°F.
D) 145°F
This option is also incorrect. 145°F is much higher than the conversion result from 50 degrees Celsius, which is established as 122°F through the correct formula.
Conclusion
The correct answer of 122°F is confirmed through the temperature conversion formula, which accurately translates 50 degrees Celsius into Fahrenheit. The other options fail because they either overshoot or undershoot the correct temperature, demonstrating a misunderstanding of the conversion process.
