16. Convert the following temperatures from Celsius to Fahrenheit and round off the answers to the nearest one- tenth of a degree. a. \( 30^{\circ} \mathrm{C} \) b. \( 62^{\circ} \mathrm{C} \) c. \( 15^{\circ} \mathrm{C} \) d. \( 25.6^{\circ} \mathrm{C} \)

To convert temperatures from Celsius (°C) to Fahrenheit (°F), you can use the following formula: \[ F = \left( \frac{9}{5} \times C \right) + 32 \] Here, \( C \) is the temperature in Celsius, and \( F \) will be the temperature in Fahrenheit. We'll apply this formula to each part of the problem and round the results to the nearest tenth of a degree. ### a. \( 30^{\circ} \mathrm{C} \) \[ \begin{align*} F &= \left( \frac{9}{5} \times 30 \right) + 32 \\ &= (54) + 32 \\ &= 86.0^{\circ} \mathrm{F} \end{align*} \] ### b. \( 62^{\circ} \mathrm{C} \) \[ \begin{align*} F &= \left( \frac{9}{5} \times 62 \right) + 32 \\ &= \left( 111.6 \right) + 32 \\ &= 143.6^{\circ} \mathrm{F} \end{align*} \] ### c. \( 15^{\circ} \mathrm{C} \) \[ \begin{align*} F &= \left( \frac{9}{5} \times 15 \right) + 32 \\ &= (27) + 32 \\ &= 59.0^{\circ} \mathrm{F} \end{align*} \] ### d. \( 25.6^{\circ} \mathrm{C} \) \[ \begin{align*} F &= \left( \frac{9}{5} \times 25.6 \right) + 32 \\ &= \left( 46.08 \right) + 32 \\ &= 78.08^{\circ} \mathrm{F} \\ &\approx 78.1^{\circ} \mathrm{F} \quad (\text{rounded to the nearest tenth}) \end{align*} \] --- **Summary of Converted Temperatures:** a. \( 30^{\circ} \mathrm{C} = 86.0^{\circ} \mathrm{F} \) b. \( 62^{\circ} \mathrm{C} = 143.6^{\circ} \mathrm{F} \) c. \( 15^{\circ} \mathrm{C} = 59.0^{\circ} \mathrm{F} \) d. \( 25.6^{\circ} \mathrm{C} = 78.1^{\circ} \mathrm{F} \)
