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.
30 mins × 5.5mi/h = 165
15 mins × 6mi/h = 90
add 165 and 90 together
165 + 90 = 255
255 miles
So since the amount of dog food is 3 times more than water, then we can simply multiply 16 by 3. That is equal to 48.
48 cups of dog food can be softened with 16 cups of water! Hope this helps!
