Question

A meterstick standing vertically casts a shadow 1.5 meters long on the ground. At the same time, a nearby tree casts a shadow 9 meters long on the ground. About how tall is the tree? Please Help!!!

Answer 1

Someone help me please?

Answer 2

If a 1 meter stick casts a 1.5, it's an extra 50% of the shadow.

1 x 0.50 = 0.5

1 + 0.5 = 1.5

By that logic a 2 meter stick would cast a 3 meter shadow, because

2 x 0.50 = 1

2 + 1 = 3

So:
|Y x 0.50 = Z | Y = 2Z | Y = 2Z | Y = 2 x 3 | Y = 6
< = < < < <
|Z + Y = 9 | Z + 2Z = 9 | 3Z = 9 | Z = 3 | Z = 3


Hope it helped, If someone thinks it should be diferent, please correct me.

Answer 3

I'm not a teacher, or a specialist, but i believe this is how it should be done... Not 100% correct if it has got to deal with percentages though.
