7 pigeons sitting on the branches, 5 pigeons under the tree
=12 in total
Upper branch has x pigeons, lower has y.
Top branch said: "If one of you flies up to us our number will be double yours":
Well, if one of the bottom branch flies up, the top branch will have x+1 birds and the bottom will have (y−1). The top will have double the bottom, so:
Top branch said: "If one of us flies down to you, our numbers will be equal":
Now, the top branch will have x−1 and the bottom y+1. The numbers should be equal:
how is that middle school
there is a formula i can give you:
it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.
plug them in:
(10sqrt(3))^2*6*sin(360/6) divided by 2
100*3*6*sin(60) divided by 2
approx is 779.4 cm^2
