An oven heating element turns on when the internal temperature falls to 20 degrees below the set temperature and turns off when
son4ous [18]

Answer:

The range of the oven is 385\leq T\leq 410

Step-by-step explanation:

Consider the provided information.

The internal temperature falls to 20 degrees below the set temperature and turns off when the temperature reaches 5 degrees above the set temperature.

You preheat the oven to 405 degrees before putting a cake in and baking it for an hour at 405.

The internal temperature falls to 20 degrees, therefore the lowest set can be:

405-20=385 degree.

The temperature reaches 5 degrees above the set temperature 405, therefore the upper set is: 405+5=410 degree.

Hence, the temperature will be lying between 385 degree and 410 degree.

This can be written as: 385\leq T\leq 410

Hence, the range of the oven is 385\leq T\leq 410
