Convert \( 57^{\circ} \mathrm{F} \) to degrees Celsius. If necessary, round your answer to the nearest tenth of a degree. Here are the formulas. \[ C=\frac{5}{9}(F-32) \] \[ F=\frac{9}{5} C+32 \]

To convert \( 57^{\circ} \mathrm{F} \) to degrees Celsius, you can use the formula \( C=\frac{5}{9}(F-32) \). Substituting in the values, we have: \[ C = \frac{5}{9}(57 - 32) = \frac{5}{9}(25) \approx 13.9^{\circ} \mathrm{C}. \] So, \( 57^{\circ} \mathrm{F} \) is approximately \( 13.9^{\circ} \mathrm{C} \) when rounded to the nearest tenth of a degree. Fun Fact: The Celsius and Fahrenheit scales have different zero points and increments. While 0 °C represents the freezing point of water, 0 °F is much colder, equating roughly to -17.78 °C! Real-world Application: Knowing how to convert between these temperature scales is super helpful for traveling, cooking, or following international weather forecasts. For instance, if you're baking a cake from a recipe that requires Celsius and you only have a Fahrenheit oven, you can easily make the conversion and ensure your baking turns out perfect!
