Answer:
it has to be 60
Step-by-step explanation:
4 x 15 = 60
N=30°. The sum of the angles is 180º. n+n+4n=6n, so 6n=180 and n=30°.
n=18°. 4n+n=90, so 5n=90, n=18°.
Answer:
g(f(-4)) = -8
f(g(x)) = 13-10x
Step-by-step explanation:
g(f(-4)):
Plug in the equation f(x) into the variable x of g(x), we have:

Plug in x = -4 and the answer is -8
f(g(x)):
Plug in the equation g(x) into the variable x of f(x), we have:

The answers to the question are:
<h3>a. How to determine the service charge rate for the month of October</h3>
This is the number of calls for the help desk
160000/3200 = 50per call
network center
735000/9800
= 75 per device that was monitored
Electronic mail
100000/10000 =
10 for the mail account
For smart phone support
124600/8900
= 14 per phone extension
<h3>b. Charges to the COMM sector </h3>
for helpdesk
5200 * 0.25 * 0.96 *1.5 calls * $50
= 93600
For network center
(5200 * 0.25 * 0.96) + 600] x 75
= 138600
For Electronic mail
5200 * 0.25 * 0.96 * 10 per email account
= 12480
Smart support charge
5200 * 0.25 * 14 = 18200
