The formula for finding the surface area of a cube is A=6y^2 where y is the side length. we know a=96. so we just isolate y.
96/6= 6y^2 / 6
16=y^2
sqrt (16) = sqrt(y^2)
4=y
So y is 4
The rate of interest is 75 % per year
<em><u>Solution:</u></em>
Given that, Jamerra received a $3,00 car loan
she plans on paying off the loan in 2 years
<em><u>Jamerra will have paid $450 in interest</u></em>
Therefore, we get
Principal = $ 300
Number of years = 2
Simple Interest = $ 450
Rate of interest = ?
<em><u>The simple interest is given by formula:</u></em>
![simple\ Interest = \frac{p \times n \times r}{100}](https://tex.z-dn.net/?f=simple%5C%20Interest%20%3D%20%5Cfrac%7Bp%20%5Ctimes%20n%20%5Ctimes%20r%7D%7B100%7D)
Where,
"p" is the principal and "n" is the number of years and "r" is the rate of Interest
<em><u>Substituting the given values we get,</u></em>
![450 = \frac{300 \times 2 \times r}{100}\\\\450 = 3 \times 2 \times r\\\\6r = 450\\\\r = \frac{450}{6}\\\\r = 75](https://tex.z-dn.net/?f=450%20%3D%20%5Cfrac%7B300%20%5Ctimes%202%20%5Ctimes%20r%7D%7B100%7D%5C%5C%5C%5C450%20%3D%203%20%5Ctimes%202%20%5Ctimes%20r%5C%5C%5C%5C6r%20%3D%20450%5C%5C%5C%5Cr%20%3D%20%5Cfrac%7B450%7D%7B6%7D%5C%5C%5C%5Cr%20%3D%2075)
Thus rate of interest is 75 % per year
Answer:
Y=3x+12 (its the first option)
Step-by-step explanation:
I did the assignment.
Answer:
Option 4.) month 4
Step-by-step explanation:
we have
----> equation A
----> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
The solution is the point (3,27)
That means -----> For x=3 months, the populations in both functions are the same (the bacteria populations is 27)
therefore
For x> 3 months the f(x) population is greater then the g(x) population
Answer:
geometric (so it's a 1:3 ratio I believe)
Step-by-step explanation:
you're multiplying by 3 each time
