Answer:
8 blue ties to 21 ties (8/21
Step-by-step explanation:
You take the amount of blue ties and the put them over the total amount of ties (Blue + Grey + Black + Red)
Answer:
Step-by-step explanation:
I don't know if this is what you are looking for but, I would use substitution to solve what x and y are
6x+2y = 1
is the same as -6x-2y= -1 because if you multiply everything by -1 it will equal
6x+2y = 1
so now you have
6x+2y = 1
6x+2y = 1
I would set the equation equal to one variable and substitute.
6x+2y = 1 = 2y = 1 - 6x = y = (1/2) - (6x/2) = y = (1/2) - 3x
now plug in (1/2) - 3x in to one of the y's because they are the same equation
6x + (1/2) - 3x = 1
subtract 1/2
6x - 3x = 1/2
subtract the x's
3x = 1/2
now divide both sides by 3
x = (1/2)/ 3
x = 1/6
now that you know what x equals, plug that into the equation and find y
6(1/6) + 2y = 1
1 + 2y = 1
subtract 1
2y = 0
now divide to find y
y = 0/2
y = 0
so
x = 1/6 and y = 0
The equation would be
V= \pi r^{2} h[/tex]
so if you substitute, you'd have to solve for the radius, which can be found by doing
![r= \frac{1}{2} (115*2012)](https://tex.z-dn.net/?f=r%3D%20%5Cfrac%7B1%7D%7B2%7D%20%28115%2A2012%29)
This gives you
![r=115,690](https://tex.z-dn.net/?f=r%3D115%2C690)
So now we can solve for the volume by using the substituted values in the original equation
![V=(3.14)(115690)^{2}(2012)](https://tex.z-dn.net/?f=V%3D%283.14%29%28115690%29%5E%7B2%7D%282012%29)
which simplifies down to
![8.455694166 x 10^{13}](https://tex.z-dn.net/?f=8.455694166%20x%2010%5E%7B13%7D)
so you could answer
![V=8.46 * 10^{13}](https://tex.z-dn.net/?f=V%3D8.46%20%2A%2010%5E%7B13%7D)
or
84556941663448.00
I would recommend the one in scientific notation
Hi there!
Your question:
Sales fall from 300 per week to 270 per week what's the percentage change?
My answer:
The formula for calculating percent change is as follows:
[(y2 - y1)/y1]*100=your percent change
y2= first value
y1=second value
Plug the numbers in:
[(300-270)/300]*100
[30/300]*100
0.1*100
10
Therefore, the percent change is 10%
Hope this helps! Let me know if it's incorrect so I can fix it:)
