Answer:
1/6
Step-by-step explanation:
There are six factors of 12: 1, 2, 3, 4, 6, and 12.
So the probability that the chosen factor is 4 is 1/6.
Answer:
![100.48\ m^2](https://tex.z-dn.net/?f=100.48%5C%20m%5E2)
Step-by-step explanation:
<u><em>The complete question in the attached figure</em></u>
we know that
To find out how much area of carpet is left after putting the table in place, subtract the area of the table from the area of the carpet
Remember that
The area of a circle is equal to
![A=\pi r^{2}](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E%7B2%7D)
step 1
Find the area of the carpet
we have
----> the radius is half the diameter
assume
![\pi =3.14](https://tex.z-dn.net/?f=%5Cpi%20%3D3.14)
substitute
![A=(3.14)(6)^{2}=113.04\ m^2](https://tex.z-dn.net/?f=A%3D%283.14%29%286%29%5E%7B2%7D%3D113.04%5C%20m%5E2)
step 2
Find the area of the circular table
we have
----> the radius is half the diameter
assume
![\pi =3.14](https://tex.z-dn.net/?f=%5Cpi%20%3D3.14)
substitute
![A=(3.14)(2)^{2}=12.56\ m^2](https://tex.z-dn.net/?f=A%3D%283.14%29%282%29%5E%7B2%7D%3D12.56%5C%20m%5E2)
step 3
Subtract the areas
![113.04-12.56=100.48\ m^2](https://tex.z-dn.net/?f=113.04-12.56%3D100.48%5C%20m%5E2)
Answer:
You don't really need to do it, but it helps you keep things more organized and easier to follow. Imagine if you're doing some multi-variable equation,
2a + 5b + 4d + 3c + b + a + 2d
that looks like a mess, it'll be easier to look at if you put all the similar variables next to each others like this:
a + 2a + b + 5b + 3c + 2d + 4d
(a + 2a) + (b + 5b) + 3c + (2d + 4d)
now you can add them up much easier.
Step-by-step explanation:
-(-5x + 3) = 17
5x - 3 = 17
5x = 20
x = 4.
