Answer:
first do 9x40 and get your answer then do 18x3 and get that answer and then add to do answers together
Answer: y=-5x-16
Step-by-step explanation:
Since we are given the slope and the point, we can plug in the point to solve for y-intercept.
4=-5(-4)+b [multiply]
4=20+b [subtract both sides by 20]
b=-16
Now, we know the equation is y=-5x-16.
8/13 = 0.6153
y = cos-1(0.6153)
y = 52.0
I'm not totally sure if this is what you mean or if this is.
y = cos(8/13) = 0.9999 which to the nearest tenth is 1.0
Answer:
The equation 
gives average time spent on 35 rehearsals.
Step-by-step explanation:
We are supposed to find that what question does the equation finds answer of.
We can see that 35x represents time spent on 35 rehearsals and 
is time spent on other responsibilities related to play. The sum of these times equals to total time spent on preparing the play.
Now let us solve our equation step by step.
After subtracting hours from 190 hours we will get time spent on 35 rehearsals.
Time spent on 35 rehearsals is 96.25 hours and we are told that each rehearsal took different amount of time. Dividing 96.25 by 35 we will get average time spent on each rehearsal.
Therefore, equation finds average time spent on 35 rehearsals.
