Add all of the interior angles to 1260. Then you simplify for x. After that you plug in what you found for X in the E expression.
So to find the mean you add up all the numbers (or the exam scores) which will get you 212 then you take the number and divide it by the total numbers in the set (how many numbers did you add up?)
212 divided by 8 is 26.5 which would be C. I hope this helps!
Answer:
192
Step-by-step explanation:
so basically when a problem like this is given out and you do not understand the question or just don't want to the best thing you can do is pick B
8 gallons= 128 cups
20 guests x 2 cups each= 40 cups will be gone
128-40= 88 cups left over
88 cups= 5.5 gallons of punch left at the end of the party.
is conservative if we can find a scalar function 
such that 
. This would require
Integrating both sides of the first equation wrt 
gives
Differentiating both sides of this wrt 
gives
but we assumed 
was a function of and 
, independent of . So there is no such and 
is not conservative.
To find the work, first parameterize the path (call it 
) by
for 
. Then
and the work is given by the line integral,
