A flagpole that is 40ft in height casts a shadow that is 25ft in length. If a nearby building is 200ft tall, and the sun hits it

at the same angle as the tree, what is the length of the building’s shadow?

Answer:

I would assume that the shadow length is proportional to the height of the flagpole. Hence as the building is 5 times higher than the flagpole, the length of the shadow would be 5 times higher, 25x5= 125 ft.

Answer:

125 ft

Step-by-step explanation:

Since you know the height  of the pole and the shadow you can write it as a ratio of 40/25. Knowing that the sun hits the building at the same angle you can set up the equation as 40/25 = 200/x where x is the length of the shadow of the building.

  • 40/25  = 200/x
  • 40 = 5000/x          Multiply the 25 to the other side
  • 40x = 5000           Multiply the x to the other side. No more fractions!
  • x = 125

Are two figures that have the same size and shape similar?
iogann1982 [59]
No, they're not, if a figure obtains the same shape, and size doesn't mean they're similar. Even though they have two similarities, volume and mass come into play. Figures of all shapes and sizes, even those that are the same, can embody a different volume and mass. 

Example: Toni has a sphere that's the same size of sphere B. Toni has to figure out why one sphere is different from the other. What are some reasons why the spheres are not similar? 

Well, the objects can be made out of different materials. Sphere A could be made out of wood while Sphere B could be made out of copper. Same object, same size, different mass, and volumes. As we know, copper is typically heavier than wood, so, it really all comes down to what the object is created with. 

I hope I helped :)
