From midnight to 9:00 am, the temperature rose (3)/(5)^(@)C each hour. If the temperature at midnight was -9^(@)C, what was the temperature at 9:00 am? Answer: ^(@)C

Calculate Total Temperature Increase: Determine the total temperature increase over 9 hours. Since the temperature rises by (3)/(5)°C each hour, we need to multiply this hourly increase by the number of hours from midnight to 9:00 am. (3)/(5)°C/hour * 9 hours = (3*9)/(5)°CCalculate Total Increase: Calculate the total temperature increase. (3*9)/(5)°C = 27/5°C 27/5°C = 5.4°C This is the total temperature increase from midnight to 9:00 am.Calculate Temperature at 9:00 am: Calculate the temperature at 9:00 am. The temperature at midnight was -9°C. We add the total temperature increase to the initial temperature to find the temperature at 9:00 am. -9°C + 5.4°C = -3.6°C

Answer:

\square

{ }^{\circ} \mathrm{C}

Calculate Total Temperature Increase: Determine the total temperature increase over $9$ hours. $\newline$ Since the temperature rises by $(3)/(5)\degree C$ each hour, we need to multiply this hourly increase by the number of hours from midnight to $9:00$ am. $\newline$ $(3)/(5)\degree C$ /hour $\times 9$ hours $= (3\times9)/(5)\degree C$
Calculate Total Increase: Calculate the total temperature increase. $\newline$ $(3\times9)/(5)^\circ\text{C} = 27/5^\circ\text{C}$ $\newline$ $27/5^\circ\text{C} = 5.4^\circ\text{C}$ $\newline$ This is the total temperature increase from midnight to $9:00$ am.
Calculate Temperature at $9$ : $00$ am: Calculate the temperature at $9$ : $00$ am. $\newline$ The temperature at midnight was $-9^\circ\text{C}$ . We add the total temperature increase to the initial temperature to find the temperature at $9$ : $00$ am. $\newline$ $-9^\circ\text{C} + 5.4^\circ\text{C} = -3.6^\circ\text{C}$
