<span>R = 11 - 2m
S = n + 5
T = -m - 3n + 8
R - S + T
(</span>11 - 2m) - (n + 5) + (-m - 3n + 8)
6 - 2m - n - m - 3n + 8
14 - 3m - 4n
-3m - 4n + 14
SOLUTION
We want to find the area of the circle in the picture given.
We have been given the formula as
From the circle, the radius r = 11 in.
The area of the circle becomes
Hence the answer is 363 square-inches
If the entire class lasts 7/8 of an hour, then it lasts 52.5 minutes as:
60/8 * 7 = 52.5mins or 52min 30secs
a) Then warm up and cool down lasts 3/10 of the class so this is:
52.5/10 * 3 = 15.75mins or 15min 45secs
b) Instruction is 1/5 of the class so 4/5 is not spent on instruction so:
52.5 / 5 * 4 = 42mins
I believe this problem has the following table for long
distance call:
0-1 minutes 2-5 minutes 6+ minutes
Long distance 170 120 10
To solve this problem, let us first recall what
probability means:
Probability = number of successful event / number of
total events
In this case, an event is considered to be successful
when the long distance call is not 6+ minutes long. Therefore:
number of successful event = 170 + 120 = 290
Now the number of total events is the sum of all number
of calls, hence,
number of total events = 170 + 120 + 10
number of total events = 300
Probability that the call is not 6+ minutes long is
therefore:
Probability = 290 / 300
Probability = 0.9667
or
Probability = 96.67%
