For this case we are going to assume the following:
m: whole number greater than zero.
n: integer greater than zero.
Where,
n> m
According to these assumptions, the percentage of growth is given by the following formula:
Answer:
the number of students did grow by:
The best option is the first one (Six yards of rope costs $5.50). It is the lowest unit cost.
<u>Step-by-step explanation:</u>
For the given question case, first we should compare the unit costs of the choices provided and evaluate the best option.
Choice 1:
Six yards of rope costs $ 5.50
![\frac{5.50 \text { dollar}}{6 \text { yard }}=0.9167\ dollar/yard](https://tex.z-dn.net/?f=%5Cfrac%7B5.50%20%5Ctext%20%7B%20dollar%7D%7D%7B6%20%5Ctext%20%7B%20yard%20%7D%7D%3D0.9167%5C%20dollar%2Fyard)
Choice 2:
Four yards costs $ 4.75
![\frac{4.75 \text { dollar}}{4 \text { yard }}=1.1875\ dollar/yard](https://tex.z-dn.net/?f=%5Cfrac%7B4.75%20%5Ctext%20%7B%20dollar%7D%7D%7B4%20%5Ctext%20%7B%20yard%20%7D%7D%3D1.1875%5C%20dollar%2Fyard)
Thus, the best choice is the first one. Because it is the lowest unit cost.
Here are some simple equations that can be a life saver with this stuff :
vol of a sphere =
![v = \frac{3}{4} \pi \: {r}^{3}](https://tex.z-dn.net/?f=%20v%20%3D%20%5Cfrac%7B3%7D%7B4%7D%20%5Cpi%20%5C%3A%20%7Br%7D%5E%7B3%7D%20)
Circumference =
![2 \times \pi \times r](https://tex.z-dn.net/?f=2%20%5Ctimes%20%5Cpi%20%5Ctimes%20r)
sorry this might not be very helpful. I haven't don't this since last year. You basically have to work backwards. so plug in 972 for V and then do (3/4)×3.14.
then take the answer u got for ^^ and divide it by 2? not sure.
Answer: c divided by 3=15.5
