An average is just the total attendance numbers / the number of performances.
Let's let the number of people in the third show be equal to x so we can write this as a formula, it's easier to read. x is just "some number we don't know"
The average is
Average=Total attendance/3
So
3000=(2580+2920+x)/3
So let's multiply by that 3 on both sides, make x easier to find
Average*3=2580+2920+x ( * means multiplied)
The average is 3000
So
2580+2920+x=3000*3
2580+2920+x=9000
Then we subtract those other attendances to get x on its own.
x=9000-2580-2920
x=3500
Answer:
5 radians
Step-by-step explanation:
The circumference of the circle is
C = 2 * pi *r
C = 2 * pi * 3
C = 6 pi
The arc length that we are measuring is 15
The fraction of the circumference is
15/(6pi)
5/(2 pi)
We want to know the fraction of 2 pi that the angle is
5 x
------- = -------------
2 pi 2 pi
Using cross products
5*2 pi = x * 2pi
Dividing each side by 2pi
10 pi/ 2 pi = x * 2pi/ 2pi
5 =x
5 radians
To know how to do this set up the question:
63/x = 60/100
63*100=60x
6300/60=x
x=105
