Answer:
545.119
Step-by-step explanation:
75 * (1 + .2/12)^10 * 12
75 * (1.016667)^10*12
Now things get a little tricky. What does 10*12 mean? I'm taking it to mean 120
75 * (1.016667)^120
75 * 7.268
545.119

Answer:
Step-by-step explanation:
80 minutes.......8 minutes played commercials....that means (80 - 8) = 72 minutes played music
so the ratio of music to commercials is : 72/8 which reduces to 9/1...so the ratio is 9:1 <=== ur answer
** pay attention to the wording, because if it would have asked for the ratio of commercials to music, it would have been 8/72....ratio would be 1:9
Answer:
Step-by-step explanation:
How can you remember the formula?
Well, it helps to know it's the Pythagoras Theorem with something extra so it works for all triangles:
Pythagoras Theorem:
(only for Right-Angled Triangles) a2 + b2 = c2
Law of Cosines:
(for all triangles) a2 + b2 − 2ab cos(C) = c2
So, to remember it:
think "abc": a2 + b2 = c2,
then a 2nd "abc": 2ab cos(C),
and put them together: a2 + b2 − 2ab cos(C) = c2
