Amoving company charges $45 on arrival and $25 and hour. their final bill was $470. how many hours did they work.

Let's x to be hours that company worked.

Then, $ 25x should be billed for x hours.

Altogether is going to be charged $ 45 + 25x.

So,

45 +25x =470

25x = 425

x= 17 (hours)

a company worked 17 hours.

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.
