Answer:
Each side is 6 units.
Step-by-step explanation:
The problem is not how to do the question. The problem is how to get your calculator to do the question.
V = s^3
s = ?
V = 216
So what you need is the cube root of 216
s^3 = 216
cube root(s^3) = cube root(216)
s = cube root 216
Your calculator should have a y^x or x ^y key.
Put in 216
Press the y^x key or the x^y key
Put in 0.33333333333
You should get something like 5.999999 which you should round to 6.
City A is 25% less than population of city B. So city A's population is 75% of city B
<h3>
<u>Solution:</u></h3>
Given that City A is 25% less than population of city B
To find: city A's population is what % of city B
From given information,
City A is 25% less than population of city B
A = B - 25% of B
So we can write as,
![A = B - \frac{25}{100} \times B\\\\A = B - 0.25B\\\\A = 0.75B](https://tex.z-dn.net/?f=A%20%3D%20B%20-%20%5Cfrac%7B25%7D%7B100%7D%20%5Ctimes%20B%5C%5C%5C%5CA%20%3D%20B%20-%200.25B%5C%5C%5C%5CA%20%3D%200.75B)
A = 0.75B can be written as,
![A = \frac{75}{100}\times B](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B75%7D%7B100%7D%5Ctimes%20B)
city A = 75 % of City B
Thus city A's population is 75% of city B

Answer:
D
Step-by-step explanation:
When something depreciates completely, it will have a total value of 0 dollars. Therefore, set the equation to zero and solve for <em>t</em> to find the years.
![S(t)=-105t+945\\0=-105t+945\\-105t=-945\\t=9](https://tex.z-dn.net/?f=S%28t%29%3D-105t%2B945%5C%5C0%3D-105t%2B945%5C%5C-105t%3D-945%5C%5Ct%3D9)
Therefore, the table saw will completely depreciate after 9 years.
