The pattern increases by 2 each time.
1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 + 21 +23 = 144

There are 12 rows in the display.
I hope this helped! c:
<span>Disagree. A rational number is any number that can be written as a fraction of two integers. Tom wrote 3/47, and both 3 and 47 are integers. Just because the decimal has not yet terminated doesn’t mean that the number he is looking at is irrational.</span>
B*h=A, where b equals the length of the base and h equals the length of the height.

Answer:
36.
Step-by-step explanation:
We are asked to find the number of ways in which 3 girls can divide 10 pennies such that each must end up with at least one penny.
The selection can be done by selecting two dividing likes between the 10 pennies such that the set is divided into three parts.
Since each girl must have one penny, so no girl can have 0 penny. So the dividing like cannot be placed at end points, beginning and at the end. Therefore, we are left with 9 positions.
Now we need to find number of ways to select two positions out of the 9 positions that is C(9,2).
![_{2}^{9}\textrm{C}=\frac{9!}{7!*2!}=\frac{9*8*7!}{7!*2*1}=\frac{9*8}{2}=9*4=36](https://tex.z-dn.net/?f=_%7B2%7D%5E%7B9%7D%5Ctextrm%7BC%7D%3D%5Cfrac%7B9%21%7D%7B7%21%2A2%21%7D%3D%5Cfrac%7B9%2A8%2A7%21%7D%7B7%21%2A2%2A1%7D%3D%5Cfrac%7B9%2A8%7D%7B2%7D%3D9%2A4%3D36)
Therefore, there are 36 ways to divide 10 pennies between 3 girls.
