20 experts can solve a complex mathematical question in 60 minutes. 20 dull people can solve the same complex mathematical question in 180 minutes. If 10 experts and

10 dull people sit to solve the same question, how many hours will they take

10*1/20*1+10*1/20*3

(hints 1 experts =1/20*60mins and 1 dull =1/20*180mins)

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine
