Which of the following is equal to a temperature of 50°F?

• A. 32°C
• B. 46°C
• C. 18°C
• D. 10°C

Answer: (D)

Verified step by step guidance

1. Recall the formula to convert Fahrenheit (°F) to Celsius (°C): \(\displaystyle C = \frac{5}{9} (F - 32)\).
2. Substitute the given Fahrenheit temperature, 50°F, into the formula: \(\displaystyle C = \frac{5}{9} (50 - 32)\).
3. Calculate the difference inside the parentheses: \(50 - 32 = 18\).
4. Multiply by \( \frac{5}{9} \) to find the Celsius temperature: \(\displaystyle C = \frac{5}{9} \times 18\).
5. Simplify the multiplication to find the Celsius equivalent of 50°F and compare it to the given options to identify the correct match.
