No, 5(x-1) expands out to make 5x-5. So 5x-1 and 5x-5 aren’t equivalent.

Answer:
1/1001 < 4/10 < 49/100 < 357/10
Step-by-step explanation:
4/10 => 0.4
49/100 => 0.49
357/10 => 35.7
1/1001 => 0.0009
Ascending order is from smallest to the greatest.
It is about 41.4% according to my TI-83/84 calculator.
Answer:
D) 32,357mm^3
Step-by-step explanation:
Given
![Quarters = 40](https://tex.z-dn.net/?f=Quarters%20%3D%2040)
![Thickness = 1.75mm](https://tex.z-dn.net/?f=Thickness%20%3D%201.75mm)
![diameter = 24.26mm](https://tex.z-dn.net/?f=diameter%20%3D%2024.26mm)
First, we calculate the volume of 1 roll.
The volume of the cylinder is:
![V = \pi r^2h](https://tex.z-dn.net/?f=V%20%3D%20%5Cpi%20r%5E2h)
Where
![r = \frac{1}{2} * diameter](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%2A%20diameter)
![r = \frac{1}{2} * 24.26mm](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%2A%2024.26mm)
![r = 12.13mm](https://tex.z-dn.net/?f=r%20%3D%2012.13mm)
And the thickness represents the height.
So:
The volume is:
![V = 3.142 * 12.13^2 * 1.75](https://tex.z-dn.net/?f=V%20%3D%203.142%20%2A%2012.13%5E2%20%2A%201.75)
![V = 809.03mm^3](https://tex.z-dn.net/?f=V%20%3D%20809.03mm%5E3)
The volume of the 40 is:
![Roll= 40 * 809.03mm^3](https://tex.z-dn.net/?f=Roll%3D%2040%20%2A%20809.03mm%5E3)
![Roll=32361.20mm^3](https://tex.z-dn.net/?f=Roll%3D32361.20mm%5E3)
The closest option is (d):
