9. What temperature in Fahrenheit is 50°C? (Enter a numeric value only. If rounding is necessary, round to the nearest whole number.)
Answer: B
122°F
To convert 50°C to Fahrenheit, the formula used is F = (C × 9/5) + 32. Applying this formula results in 122°F, making this the correct answer.
A) 150°F
150°F is incorrect because it represents a much higher temperature than what is calculated from 50°C. When applying the conversion formula, the resulting Fahrenheit temperature is significantly lower than this option.
B) 122°F
122°F is the correct answer. By using the conversion formula F = (50 × 9/5) + 32, we find that 50°C indeed converts to 122°F, confirming this option as accurate.
C) 120°F
120°F is incorrect because it is slightly lower than the correct conversion of 122°F. The calculation shows that 50°C results in a Fahrenheit temperature that is greater than this option.
D) 145°F
145°F is also incorrect as it exceeds the calculated temperature from the conversion. The value calculated from 50°C is below this option, confirming it is not the correct answer.
Conclusion
The correct answer is 122°F, derived from the proper application of the temperature conversion formula. All other options, 150°F, 120°F, and 145°F, do not accurately reflect the conversion from Celsius to Fahrenheit for the given temperature, demonstrating their incorrectness.
