428 rounded to the nearest hundred = 400
P(B) = Area of B/(Area of A + B + C + D)
Area B = 12 in^2
Area A = 35 in^2
Area C = 16 in^2
Area D = 3 x (4+5) = 27 in^2
Hence, P(B) = 12/(12+35+16+27) = 2/15
This is the concept of proportionality, we are required to calculate for the number of hours two crews can use to paint the house altogether.
Here proceed as follows;
number of hours new crew can paint=12 hrs
portion of work painted by new crew in 1 hour= 1/12
number of hours experienced crew can paint=6 hours
Portion of work painted by experienced crew in 1 hour=1/6
Portion of work painted by the two crews altogether in 1 hour will be:
1/6+1/12=1/4
thus the total amount of hours that the two painters will take to paint will be:
4 hours
