The temperature of a hot steak starts at 140f and decreases at 5f per minute what will the temperature of this steak after a cer

irina1246 [14]

Answer:

T(m) = (140 - 5m)

Step-by-step explanation:

Given that :

Initial temperature, a = 140 F

Rate of decrease = 5 F per minute

Given a certain Number of minutes, m

Temperature, T after m minutes ;

Using the formula :

Final temperature = Initial temperature - 5*number of minutes)

T(m) = (140 - 5m)

Given that ; m = 10

T(10) = 140 - 5(10)

T(10) = 140 - 50

T(10) = 90 F

A circle has a diameter of 29 feet. What is the area? *

11111nata11111 [884]

Answer:

The answer is

<h2>660.5 square feet</h2>

Step-by-step explanation:

Area of a circle = πr²

where r is the radius

From the question

diameter = 29 feet

To find the radius given the diameter we use the formula

$radius = \frac{diameter}{2} \\ radius = \frac{29}{2} \\ = 14.5 \: \: feet$

So the area of the circle is

$A = {14.5}^{2} \pi \\ = 210.25\pi \\ = 660.519...$

We have the final answer as

<h3>660.5 square feet</h3>

Hope this helps you
