Question

an object cools at a rate of 4f per minute. its initial temperature is 10f what is the temperature of the object after 3 minutes

Answer 1

The final temperature is -2f.

Explanation:

An object cools at a rate of 4f per minute. Its initial temperature is 10f. What is the temperature of the object after 3 minutes?

The final temperature will be represented by y.

y = 10f - (3 * 4f)

3 * 4f = 12f

y = 10f - (12f)

10f - 12f = -2f

y = -2f

The final temperature is -2f.

Answer 2

-2f

Explanation:

10f-(3x4f)

=-2f

multiply 3 minutes with the cool rate and substract it from the initial temperature
