Question

riley is preheating her oven before using it to bake. the initial temperature of the oven is 75° and the temperature will increase at a rate of 20° per minute after being turned on. what is the temperature of the oven 7 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 7 minutes: temp after t minutes:

Explanation:

Step1: Find temperature after 7 minutes

The initial temperature is \( 75^\circ \), and the rate of increase is \( 20^\circ \) per minute. After 7 minutes, the total increase is \( 20 \times 7 = 140^\circ \). So the temperature is initial temperature plus increase: \( 75 + 140 = 215^\circ \).

Step2: Find temperature after \( t \) minutes

The temperature after \( t \) minutes will be the initial temperature plus the increase over \( t \) minutes. The increase over \( t \) minutes is \( 20t \), so the temperature is \( 75 + 20t \).

Answer:

Temp after 7 minutes: \( 215^\circ \)
Temp after \( t \) minutes: \( 75 + 20t \) degrees
