Answer:
Part 1) The algebraic expression is equal to
or ![1.10n-1.10](https://tex.z-dn.net/?f=1.10n-1.10)
Part 2) The algebraic expression is equal to ![\frac{1.10}{n}](https://tex.z-dn.net/?f=%5Cfrac%7B1.10%7D%7Bn%7D)
Step-by-step explanation:
Part 1) we have (n-1) increased by 110%
110%=110/100=1.10
so
The algebraic expression of (n-1) increased by 110% is equal to multiply 1.10 by (n-1)
![1.10(n-1)](https://tex.z-dn.net/?f=1.10%28n-1%29)
Distributed
![1.10n-1.10](https://tex.z-dn.net/?f=1.10n-1.10)
Part 2) we have n^(-1) increased by 110%
110%=110/100=1.10
so
The algebraic expression of n^(-1) increased by 110% is equal to multiply 1.10 by n^(-1)
Remember that
![n^{-1}=\frac{1}{n}](https://tex.z-dn.net/?f=n%5E%7B-1%7D%3D%5Cfrac%7B1%7D%7Bn%7D)
so
![1.10(n^{-1})=1.10\frac{1}{n}=\frac{1.10}{n}](https://tex.z-dn.net/?f=1.10%28n%5E%7B-1%7D%29%3D1.10%5Cfrac%7B1%7D%7Bn%7D%3D%5Cfrac%7B1.10%7D%7Bn%7D)
Answer:
x = 22.5 cm
Step-by-step explanation:
In similar triangles, corresponding sides are in same ratio
![\frac{FG}{AB}=\frac{FH}{AC} = \frac{GH}{BC}\\\\\\ \frac{GH}{BC}=\frac{FG}{AB}\\\\\frac{x}{15}=\frac{13.5}{9}\\](https://tex.z-dn.net/?f=%5Cfrac%7BFG%7D%7BAB%7D%3D%5Cfrac%7BFH%7D%7BAC%7D%20%3D%20%5Cfrac%7BGH%7D%7BBC%7D%5C%5C%5C%5C%5C%5C%20%5Cfrac%7BGH%7D%7BBC%7D%3D%5Cfrac%7BFG%7D%7BAB%7D%5C%5C%5C%5C%5Cfrac%7Bx%7D%7B15%7D%3D%5Cfrac%7B13.5%7D%7B9%7D%5C%5C)
![x = \frac{13.5}{9}*15\\\\x = 1.5*15\\\\x = 22.5](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B13.5%7D%7B9%7D%2A15%5C%5C%5C%5Cx%20%3D%201.5%2A15%5C%5C%5C%5Cx%20%3D%2022.5)
45.75h(7.86d/h)=$359.595
Which is $359.60 to nearest cent.
So, We Need To Convert 12 Feet To Inches.
1 Foot = 12 Inches
12 Feet * 12 Inches = 144 Inches. So:
We Now Need To Figure Out How Many Times 8 Inches Goes Into 144 Inches.
144/8 = 18
So, The Answer Is B, You Would Need To Lay 18 Tiles To Cover The Path.
