Answer:
12 bags
Step-by-step explanation:
2.25 × 9 = 20.25
.50 × 10 = 5
20.25 + 5 = 25.25
47.45 - 25.25= 22.2
22.2 ÷ 1.85 = 12
Answer:
The value of given expression is 1.
Step-by-step explanation:
The given expression is
If a is a real number, then 
.
![[\because a^0=1]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5E0%3D1%5D)
Using exponent property we get,
![[\because a^{-n}=\frac{1}{a^n}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5E%7B-n%7D%3D%5Cfrac%7B1%7D%7Ba%5En%7D%5D)
Therefore the value of given expression is 1.
