Write an equation that expresses the relationship describe below. Use K as the constant of variation h varies directly as g.
An equation that expresses this relationship is ______.
A tree cast a shadow 27feet long. At the same time, a vertical rod 8 feet high costs a shadow 6 feet long. How tall is the tree?_____.
Answer provided by our tutors
(1) Time: x
So 1/6 + 1/3 = 1/x, we solve it, x = 2
So it takes 2 hours using both pipes to fill the pool
(2)
An equation that expresses this relationship is h = K*g
(3)
The height of tree is x
So
8/6 = x/27
x = 36
So the height of tree is 36 ft
