In right triangles rqs, angle s is right angle. if cosq=9/41 then sinr=

Step-by-step explanation:

given cosq = =

Then qs = 9 and qr = 41

sin r = = , hence

sin r =

The painter spent 26 hours painting the house.

Step-by-step explanation:

If the painter charged $ 950 for painting a house, and he charges $ 35 per hour plus $ 40 for the ladder rental, in order to determine how many hours of work it took to paint the house, we must make the following calculation:

950 (total charge) - 40 (ladder rental) = Total work charge

910 (total charge per work) / 35 (charge per hour) = Total hours of work

910 / 35 = 26

It took 26 hours to the painter for painting the entire house.
