You can ask for a tutor those are pretty quick it helped me a lot!
5. 6√3
6. x = 10√3 y = 30
7. x = 34 y = 17√3
8. 30
9. SinA = 3/5 CosA = 4/5
10. Tan20 = 9/x
Multiply both sides by x to get it on the other side
x(tan20) = 9
Divide 9 by tan20 to get x.
x = 9/tan20
x = 24.7
It is None of them So be smart thank you
Cost = $12,800
Time = 2 hours, 8 - 10 pm
Cost per hour = ($12800)/(2) = $6400 per hour
There are 60*660 = 3600 seconds per hour.
Therefore the cost per second is
($6400)/(3600 s) = $1.7778 per second = $1.78 per second (nearest cent)
Answer: $1.78 (nearest cent)
Answer:
