gavin is preheating his oven before using it to bake. the initial temperature of the oven is 70° and the temperature will increase at a rate of 10° per minute after being turned on. what is the temperature of the oven 13 minutes after being turned on? what is the temperature of the oven t minutes after being turned on? answer attempt 1 out of 2 temp after 13 minutes: temp after t minutes:
Answer
Explanation:
Step1: Find temperature increase in 13 minutes
The rate of temperature increase is 10° per minute. For 13 minutes, the increase is $10\times13 = 130^{\circ}$.
Step2: Calculate temperature after 13 minutes
The initial temperature is 70°. So the temperature after 13 minutes is $70 + 130=200^{\circ}$.
Step3: Find general formula for t minutes
The temperature increase in t minutes is $10t^{\circ}$. The initial temperature is 70°. So the temperature after t minutes is $70 + 10t$.
Answer:
Temp after 13 minutes: $200^{\circ}$ Temp after t minutes: $70 + 10t$
