Answer: the answer is C
Step-by-step explanation: we know this because a straight line is 180 degrees. So given 140 degrees we know that g= 40.
Answer:
<em>Alexis and Jon reads at the same rate, 0.67 page by min</em>
Step-by-step explanation:
Rate Alexis = 30/45 pages/min = 0.67 page by min
Rate Jon = 40/60 pages/min = 0.67 page by min
Rate Sal = 45/90 = 0.5 page by min
Rate Andre = 15/25 = 0.6 page by min
Then
Alexis and Jon reads at the same rate, 0.67 page by min
Best regards

Step-by-step explanation:

Answer:
The volume in such a package is 10,415.41 in³
Step-by-step explanation:
Consider the provided information.
A parcel delivery service will deliver a package only if the length plus the girth (distance around, taken perpendicular to the length) does not exceed 104 inches.
Let the dimension are x by x by y.
Where x is the variable for the square base package and y is the variable for length.
Thus l=x, b=x and h=y
Then the volume of the box is:
(∵V=lbh)
The maximum combined length and girth is 104.
Therefore, 

Substitute the value of y in volume of the box.



Substitute V'(x)=0.



Now apply second derivative test.

(Min)
(Max)
If x=52/3 then 
Substitute x = 52/3 and y = 104/3 in 

Hence, the volume in such a package is 10,415.41 in³
