Trenton has already solved 8 math problems in 30 minutes. His math challenge book has 175 problems. He plans to work for 45 minutes per day until he finishes every problem. At this rate, how many days before he finishes all of the problems?

It will take him 15 days before all of the math problems finish.

Step-by-step explanation:

8 ÷ 3 = 0.266666667

8 math problem ÷ 30 minutes = math problems per minutes

0.266666667  X 45 = 12

math problems per minute X 45 Minutes = math problems per day

175 ÷ 12 = 14.5833333

math problems per day ÷ math problem = days

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
