495*.3= 148.5
<u>346.50</u>
495-99(20%)
396-10%
<u>356.4</u>
The first one is cheaper and the 2nd sucks cux the 20 then 10 means the 10% off is of the 20 and is lower and lower means lesss $ off

Answer: The simplified form is ![\frac{1}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B9%7D)
Step-by-step explanation:
Since we have given that
![3^{-2}](https://tex.z-dn.net/?f=3%5E%7B-2%7D)
As we know the "Exponential law":
![a^{-1}=\frac{1}{a^m}](https://tex.z-dn.net/?f=a%5E%7B-1%7D%3D%5Cfrac%7B1%7D%7Ba%5Em%7D)
So, it becomes
![3^{-2}=\frac{1}{3^2}](https://tex.z-dn.net/?f=3%5E%7B-2%7D%3D%5Cfrac%7B1%7D%7B3%5E2%7D)
Now, at last it becomes,
![3^{-2}=\frac{1}{3\times 3}=\frac{1}{9}](https://tex.z-dn.net/?f=3%5E%7B-2%7D%3D%5Cfrac%7B1%7D%7B3%5Ctimes%203%7D%3D%5Cfrac%7B1%7D%7B9%7D)
Hence, the simplified form is ![\frac{1}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B9%7D)
Answer:
89:120
Step-by-step explanation:
convert the both times to minutes
2 hours is 120 mins
89:120
both divisible by 1
89:120
it cant be simplified further
