Answer:
It might help you if you knew what variable was.
A variable can be (x) or (y) or anything really it just a letter the represents a number.
In this case, when it says solve for a variable it means find what the variable equals. For example:
4x + 18 = 2
here you need to find the value of X.
x = -5
X equals negative 5 because you multiply the variable to the number:
4 x -5 = -20
-20 + 18 = 2
making the answer:
4(-5) + 18 = 2
x = -5
(hope this helps)
Answer:
(x - 3)^2 + (y + 2)^2 = 16
Step-by-step explanation:
(x - h)^2 + (y - k)^2 = r^2
r = radius
(h, k ) is center of circle.
The center of the circle is (3, 2) and r is 4.
(x - 3)^2 + (y + 2)^2
16
Best of luck :3
We know, volume of rectangular prism is given by :
![V = lbh\\\\V=\dfrac{1}{2}\times 2\times 2\ ft^2\\\\V=2\ ft^2](https://tex.z-dn.net/?f=V%20%3D%20lbh%5C%5C%5C%5CV%3D%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%202%5Ctimes%202%5C%20ft%5E2%5C%5C%5C%5CV%3D2%5C%20ft%5E2)
Volume of cubic box :
![v=a^3\\\\v=(\dfrac{1}{2})^3\ ft^3\\\\v=\dfrac{1}{8}\ ft^3](https://tex.z-dn.net/?f=v%3Da%5E3%5C%5C%5C%5Cv%3D%28%5Cdfrac%7B1%7D%7B2%7D%29%5E3%5C%20ft%5E3%5C%5C%5C%5Cv%3D%5Cdfrac%7B1%7D%7B8%7D%5C%20ft%5E3)
Number of cubes can be filled :
![N=\dfrac{V}{v}\\\\N=\dfrac{2}{\dfrac{1}{8}}\\\\N=16](https://tex.z-dn.net/?f=N%3D%5Cdfrac%7BV%7D%7Bv%7D%5C%5C%5C%5CN%3D%5Cdfrac%7B2%7D%7B%5Cdfrac%7B1%7D%7B8%7D%7D%5C%5C%5C%5CN%3D16)
Therefore, 16 cubes can be put in the bin.
Hence, this is the required solution.
