Answer:
you can fit 1000 hairs in 10 cm
Step-by-step explanation:
![10^2= .01](https://tex.z-dn.net/?f=10%5E2%3D%20.01)
![.01*1000 = 10](https://tex.z-dn.net/?f=.01%2A1000%20%3D%2010)
So every 5 inches in height, there are 32 marbles. You want to know how many marbles there are per 18 inches in height.
![\frac{32}{5} = \frac{x}{18}](https://tex.z-dn.net/?f=%5Cfrac%7B32%7D%7B5%7D%20%3D%20%5Cfrac%7Bx%7D%7B18%7D)
To get from 5 to 18, you multiply by 3.6.
Do the same thing to the numerator; 32 × 3.6 = 115.2.
Since 0.2 marbles is no marbles, you round down.
There are 115 marbles in the box.
