Atotal of 25 ljhs students and adults attended the state playoffs. it was $8 for an adult and $5 for a student. if the total was $155, how many students and adults attended?

15 students and 10 adults

Step-by-step explanation:

x + y = 25       Total number of attendants

5x + 8y = 155     Total amount earned

5(15) + 8(10) = 155     Pick numbers to sub in for x and y until you find ones that work

15 students (x) and 10 adults (y) attended the game.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
