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.

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
