A pot of stew is placed on a stove to heat. The temperature of the liquid reaches 170°F, and then the pot is taken off the burne

r and placed on a kitchen counter. The temperature of the air in the kitchen is 76°F.

With the given hint to be able to answer the question above, the equation for Newton's law of cooling is as follows:
                         T(t) = T(s) + (T0 - Ts)e^-kt
where T(t) is the body's temperature at any given time, Ts is the temperature of the surrounding, T0 is the initial temperature, and k is constant. 
Substituting the values with the given above,
                             T(t) = 76 + (170 - 76)*e^(-0.34)(7)
This gives us the answer,
                                     T(t) = 84.7 degrees F

WILL GIVE BRAINLIEST!!!

Answer:

y=448-28x

Step-by-step explanation:

Let x be the number of miles.

We have been given that Sully's car has an average fuel economy of 28 miles per gallon. The capacity of the fuel tank is 16 gallons.

Let us find the number of miles that Sully can drive with 16 gallons.

\text{Number of miles Sully can drive}=\text{16 gallons}\times \frac{\text{28 miles}}{\text{gallon}}  

\text{Number of miles Sully can drive}=\text{16}\times \text{28 miles}  

\text{Number of miles Sully can drive}=448\text{ miles}  

This means that initially Sully's car has can drive 448 miles, so at x equals 0, y will be 448.

As the car consumes 1 gallon for each 28 miles driven, so the gallons of fuel consumed in traveling x miles will be 28x. As each gallon of fuel will decrease with each 28 miles traveled, so slope of our function will be -28.

Upon substituting slope and y-intercept in slope-intercept form (y=mx+b), we will get our function as:

y=448-28x

Therefore, our required function will be: y=448-28x.

77 million to 200.2 million
Luda [366]
77 million to 200.2 millionFrom 77 million it becomes 200.2 million.It is very noticeable that it increased we only need to identify the number that has increased.=> 200.2 - 77 million = 123.2 millionNow, let's find the increase rate:=> 123.2 million / 200.2 million = 0.62Now let's convert this to percentage=> 0.62 * 100% = 62%<span>

The perimeter of a school crossing sign is 102 inches what is the length of each side
12345 [234]
Add up all sides lengths:

s+6  +    s+6    +  s  +    s    + 2s    = 102

solve for s:

6s + 12 = 102
6s = 90
s= 15


The lengths of sides are as follows:

15, 21, 21, 15, 30 inches



I hope that helps!
