Answer:
![\frac{1}{725}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B725%7D)
The sear tower is
times higher than the sears tower model
Step-by-step explanation:
we know that
The ratio of the height of the model to the height of the actual sears tower is equal to the scale factor
Let
z------> the scale factor
x-------> the height of the model
y-------> the height of the actual
so
![z=\frac{x}{y}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7Bx%7D%7By%7D)
we have
![x=24\ in](https://tex.z-dn.net/?f=x%3D24%5C%20in)
![y=1,450\ ft](https://tex.z-dn.net/?f=y%3D1%2C450%5C%20ft)
substitute
![z=\frac{24}{1,450}\frac{in}{ft}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B24%7D%7B1%2C450%7D%5Cfrac%7Bin%7D%7Bft%7D)
simplify
![z=\frac{12}{725}\frac{in}{ft}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B12%7D%7B725%7D%5Cfrac%7Bin%7D%7Bft%7D)
Remember that
![1\ ft=12\ in](https://tex.z-dn.net/?f=1%5C%20ft%3D12%5C%20in)
so
![\frac{12}{725}\frac{in}{ft}=\frac{1}{725}\frac{ft}{ft}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B725%7D%5Cfrac%7Bin%7D%7Bft%7D%3D%5Cfrac%7B1%7D%7B725%7D%5Cfrac%7Bft%7D%7Bft%7D)
