86.34 minutes was used to cool the soup to 80 °F

How can we calculate this using Newton's Law of Cooling?</h3>
Newton's Law of Cooling can be computed as :

The initial temperature is been represent by T0 which is ( 100 F)
The temperature of surrounding is been given as (69 F)
The final temperature is been given as T
t = time
we were told that the temperature of the soup move to 95 F, using 15 minutes.
Hence, T = 95 F
t = 15 min
Then we can input the values into the above equation as :

if we simplify this , we have

Then 
Then we can find the value of k as :
k= -0.012
Then we have the new equation as


Then at T=80F
we have,

t=86.34
Then if we simplify , we have t=86.34 which implies that 86.34 minutes was used to cool the soup to 80 °F

Answer:
38.5 pages
Step-by-step explanation:
11pages:2mins
x pages: 7 mins
you need to divide 7 by 2 and get 3.5, then multiply 3.5 by 11 and receive 38.5
Answer:
B
Step-by-step explanation:
The wording in the problem statement is ...
... "less than 3 years"
... "at least 3. but less than 6 years"
so we expect the inequality symbols to look like ...
... 0 ≤ x < 3
... 3 ≤ x < 6
These match <em>the second piecewise function</em>.
Answer:
Step-by-step explanation:
To start of u have to subtract 150 with 180 which is 180 (cuz its a straight line and E to get angle S
Now that we know that 180-150= 30
We add S and R then subtract by 180
so 80+ 30= 110
then we said subtract 180
180-110= 70
Now we know that angle Q is 7-
Then the bottom is RS & SE (NOT REALLY SURE)
It is a Remote Interior Angle
