First find their rates...
1/6, 1/2, and 1/3 now combined they will perform the job in one day if:
t/6+t/2+t/3=1 make all have a common denominator
t/6+3t/6+2t/6=6/6 which is equal to:
6t=6 so
t=1
So if they all work together they will complete the job in one day.
The answer would be C, $100
here is my work:
0.05 x 1000 = 50
0.15 x 100 = 150
150 - 50 = $100
I hope this helps! :)
difference between -5 and 25 is
25 + 5 = 30 degrees
answer is C.
Ramp 2=35
Ramp 1=8.............
