Temperature in degrees Fahrenheit F is related to temperature in degrees Celsius C by the formula F = (9/5)C + 32. The daily high temperature for San Francisco is how many degrees Celsius?
21 degrees Celsius is the daily high temperature for San Francisco.
Using the formula F = (9/5)C + 32, we can rearrange it to find the temperature in Celsius when given the Fahrenheit temperature. If we assume the daily high temperature is around 70 degrees Fahrenheit, solving for C gives us approximately 21 degrees Celsius.
If the high temperature were 15 degrees Celsius, converting this to Fahrenheit using the formula would yield F = (9/5)(15) + 32 = 59 degrees Fahrenheit. This value is significantly lower than the typical daily high for San Francisco.
Converting 17 degrees Celsius to Fahrenheit results in F = (9/5)(17) + 32 = 62.6 degrees Fahrenheit. While closer, this temperature still falls short of the expected daily high for the city, indicating it is not the correct choice.
When converting 21 degrees Celsius to Fahrenheit using the formula gives F = (9/5)(21) + 32 = 69.8 degrees Fahrenheit. This is consistent with the typical daily high in San Francisco, making it the correct answer.
For 25 degrees Celsius, the conversion yields F = (9/5)(25) + 32 = 77 degrees Fahrenheit. This value exceeds the usual high for San Francisco, indicating it is not a feasible temperature for the city.
The conversion from 29 degrees Celsius results in F = (9/5)(29) + 32 = 84.2 degrees Fahrenheit. This temperature is also too high for San Francisco’s typical daily high, confirming it as an incorrect option.
The relationship between Fahrenheit and Celsius temperatures is critical for accurate conversions. Among the options provided, 21 degrees Celsius represents a reasonable estimate for San Francisco's high temperature, aligning well with typical weather patterns in the region. Other options either fall below or exceed this expected temperature range, reinforcing the correctness of the chosen answer.
