A consignment of fodder can feed 1000 sheep 20 days. Assuming that all the sheep consume
fodder at the same rate, how many consignmen
of fodder are needed to feed 550 sheep for 400 days?

11 consignmen

Step-by-step explanation:

Given that a consignment of fodder can feed 1000 sheep 20 days. Assuming that all the sheep consume

fodder at the same rate, then

1000 × 20 = 20000 for 1 consignment

to feed 550 sheep for 400 days, that is

550 × 400 = 220000

The consignment that will be needed will be

220000 / 20000 = 11

Therefore, 11 consignment  fodder are needed to feed 550 sheep for 400 days.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+%2836%2fx%29%5e2+

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+

25.45584

the answer is $42.96
