In the diagram, a building casts a 20-ft shadow and a flagpole casts a 7-ft shadow. if the flagpole is 12 ft tall, how high is the building? round to the nearest tenth.

Height of Building is 34.3 ft

Step-by-step explanation:

Given Length of shadow of  building = 20 ft

Length of shadow of flagpost     = 7 ft

Height of flagpole = 12 ft

Let, height of building is x

This problem is of Direct proportion,

As when if height of object increases then length of shadow also increases at same time.

We use the result,

therefore, Height of Building is 34.3 ft

the statemwnt is the company makes small and large snow cone cups.

large=it holds more then the small

small=it holds less then the large

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
