Q. From midnight to 99:0000 am, the temperature rose 35∘C \frac{3}{5}^{\circ} \mathrm{C} each hour. If the temperature at midnight was −9∘C -9^{\circ} \mathrm{C} , what was the temperature at 99:0000 am?\newlineAnswer: □\square ∘C { }^{\circ} \mathrm{C}
  1. Calculate Total Temperature Increase: Determine the total temperature increase over 99 hours.\newlineSince the temperature rises by (3)/(5)°C(3)/(5)\degree C each hour, we need to multiply this hourly increase by the number of hours from midnight to 9:009:00 am.\newline(3)/(5)°C(3)/(5)\degree C/hour ×9\times 9 hours =(3×9)/(5)°C= (3\times9)/(5)\degree C
  2. Calculate Total Increase: Calculate the total temperature increase.\newline(3×9)/(5)∘C=27/5∘C(3\times9)/(5)^\circ\text{C} = 27/5^\circ\text{C}\newline27/5∘C=5.4∘C27/5^\circ\text{C} = 5.4^\circ\text{C}\newlineThis is the total temperature increase from midnight to 9:009:00 am.
  3. Calculate Temperature at 99:0000 am: Calculate the temperature at 99:0000 am.\newlineThe temperature at midnight was −9∘C-9^\circ\text{C}. We add the total temperature increase to the initial temperature to find the temperature at 99:0000 am.\newline−9∘C+5.4∘C=−3.6∘C-9^\circ\text{C} + 5.4^\circ\text{C} = -3.6^\circ\text{C}
