<u>Percentages</u>
To find a percentage of a given number, the procedure is multiplying the percentage by the number and divide by 100.
Han spent 75 minutes practicing the piano over the weekend and Priya practiced the violin for 152% of the time that Han did.
We need to compute:
![\frac{152*75}{100}=\frac{11400}{100}= 114](https://tex.z-dn.net/?f=%5Cfrac%7B152%2A75%7D%7B100%7D%3D%5Cfrac%7B11400%7D%7B100%7D%3D%20114)
Priya practiced for 114 minutes (1 hour and 54 minutes).

Answer:
59049 ways
Step-by-step explanation:
Given
![Colors = 9](https://tex.z-dn.net/?f=Colors%20%3D%209)
![Dogs = 5](https://tex.z-dn.net/?f=Dogs%20%3D%205)
Required
Determine number of selection (repetition is allowed)
The number of collars is not given.
So, we'll assume that there are enough collars to go round.
If no repetition is allowed, each of the 5 dogs have 9 colours to select from.
i.e.
![Dog\ 1 = 9](https://tex.z-dn.net/?f=Dog%5C%201%20%3D%209)
![Dog\ 2 = 9](https://tex.z-dn.net/?f=Dog%5C%202%20%3D%209)
![Dog\ 3 = 9](https://tex.z-dn.net/?f=Dog%5C%203%20%3D%209)
![Dog\ 4 = 9](https://tex.z-dn.net/?f=Dog%5C%204%20%3D%209)
![Dog\ 5 = 9](https://tex.z-dn.net/?f=Dog%5C%205%20%3D%209)
So, the number of selection is:
![Selection = 9 * 9 * 9 * 9 * 9](https://tex.z-dn.net/?f=Selection%20%3D%209%20%2A%209%20%2A%209%20%2A%209%20%2A%209)
![Selection = 59049](https://tex.z-dn.net/?f=Selection%20%3D%2059049)
