Hello!
If this long ribbon measures 144
feet, you can see, it was only multiplied by one number, which has the be the diameter of a column to get our circumference. If we divide this by our diameter 6 (diameter is double the radius, 3), we get our answer below.
144/6=24
Therefore, our answer is C) 24.
I hope this helps!
One bag of soil is 5/8 pounds.
you have 16 of them.
just multiply 16 by 5/8.
you could just type it into your calculator, or you could do it the long way:
![16 * \frac{5}{8} \\ \frac{16*5}{8} \\ \frac{8*2*5}{8} \\ 2*5\\10](https://tex.z-dn.net/?f=16%20%2A%20%20%5Cfrac%7B5%7D%7B8%7D%20%5C%5C%20%5Cfrac%7B16%2A5%7D%7B8%7D%20%5C%5C%20%20%5Cfrac%7B8%2A2%2A5%7D%7B8%7D%20%5C%5C%202%2A5%5C%5C10)
she has 10 pounds of potting soil.
So hmm if you check the picture below
those are the given foci and co-vertices
so, since the co-vertices are at 2,0 and -2,0 that makes the center, at the origin and the "b" component 2, so the minor axis is just 2+2 or 4
now, what's the major axis? or what is the "a" component?
based on the provided points, is a vertical ellipse, that means the major axis runs over the y-axis and thus the "a" or larger denominator, lies under the fraction with the "y"
now
![\bf \textit{ellipse, vertical major axis}\\\\ \cfrac{(x-{{ h}})^2}{{{ b}}^2}+\cfrac{(y-{{ k}})^2}{{{ a}}^2}=1 \qquad \begin{cases} center\ ({{ h}},{{ k}})\\ vertices\ ({{ h}}, {{ k}}\pm a)\\ c=\textit{distance from}\\ \qquad \textit{center to foci}\\ \qquad \sqrt{{{ a }}^2-{{ b }}^2}\\ ----------\\ h=0\\ k=0\\ b=2\\ c=6 \end{cases}](https://tex.z-dn.net/?f=%5Cbf%20%5Ctextit%7Bellipse%2C%20vertical%20major%20axis%7D%5C%5C%5C%5C%0A%0A%5Ccfrac%7B%28x-%7B%7B%20h%7D%7D%29%5E2%7D%7B%7B%7B%20b%7D%7D%5E2%7D%2B%5Ccfrac%7B%28y-%7B%7B%20k%7D%7D%29%5E2%7D%7B%7B%7B%20a%7D%7D%5E2%7D%3D1%0A%5Cqquad%20%0A%5Cbegin%7Bcases%7D%0Acenter%5C%20%28%7B%7B%20h%7D%7D%2C%7B%7B%20k%7D%7D%29%5C%5C%0Avertices%5C%20%28%7B%7B%20h%7D%7D%2C%20%7B%7B%20k%7D%7D%5Cpm%20a%29%5C%5C%0Ac%3D%5Ctextit%7Bdistance%20from%7D%5C%5C%0A%5Cqquad%20%5Ctextit%7Bcenter%20to%20foci%7D%5C%5C%0A%5Cqquad%20%5Csqrt%7B%7B%7B%20a%20%7D%7D%5E2-%7B%7B%20b%20%7D%7D%5E2%7D%5C%5C%0A----------%5C%5C%0Ah%3D0%5C%5C%0Ak%3D0%5C%5C%0Ab%3D2%5C%5C%0Ac%3D6%0A%5Cend%7Bcases%7D)
