A pizza pan is removed at 7:00 PM from an oven whose temperature is fixed at 425°F into a room that is a constant 73°F. After 5 minutes, the pizza pan is at 300°F. (a) At what time is the temperature of the pan 135°F? (b) Determine the time that needs to elapse before the pan is 160°. (c) What do you notice about the temperature as time passes? (a) The temperature of the pan is 135°F at PM. (Do not round until the final answer. Then round to the nearest minute as needed.)

(a) At what time is the temperature of the pan 135°F?
(b) Determine the time that needs to elapse before the pan is 160°.
(c) What do you notice about the temperature as time passes?
(a) The temperature of the pan is 135°F at PM.
(Do not round until the final answer. Then round to the nearest minute as needed.)
Transcribed Image Text:A thermometer reading 8°C is brought into a room with a constant temperature of
28°C. If the thermometer reads 15°C after 3 minutes, what will it read after being in
the room for 5 minutes? For 10 minutes?
After 5 minutes, the thermometer will read °C.
(Do not round until the final answer. Then round to the nearest hundredth
as needed.)
