In order to determine the correct answer, it would be helpful to set up equations. We do as follows:
Let x = students
y = adults
x + y = 215
.50x + 2y = 250
SOlving simultaneously, we have:
x = 120 students
y = 95 adults
Hope this answers the question. Have a nice day.
Investment: cost of her education + salary as sales clerk during two years
Investment = 18,000 (2) + 20,000 = 36,000 + 20,000 = 56,000
Time to recover investment = 56,000/35,000 = 1.6
In less than two years, after she starts to work Niah will have recoverd her investment.
Answer:
Since there are six possible outcomes, the probability is 1/6.
The given function is a variable separable differential equation. Combine like terms, integrate, apply the appropriate limits, and express V in terms of t. This is done as follows:
dV/dt = -3(V)^1/2
dV/-3V^1/2 = dt
![\int\limits^V_m { \frac{1}{03 \sqrt{V} } } \, dV = \int\limits^t_0 {} \, dt](https://tex.z-dn.net/?f=%20%5Cint%5Climits%5EV_m%20%7B%20%5Cfrac%7B1%7D%7B03%20%5Csqrt%7BV%7D%20%7D%20%7D%20%5C%2C%20dV%20%3D%20%5Cint%5Climits%5Et_0%20%7B%7D%20%5C%2C%20dt%20)
m here is the initial V which is 225. Then after integrating,
-2/3 (√V - √225) = t
-2/3 (√V - 15) = t
![V= \sqrt{ \frac{-3}{2}t+15 }](https://tex.z-dn.net/?f=V%3D%20%5Csqrt%7B%20%5Cfrac%7B-3%7D%7B2%7Dt%2B15%20%7D%20)
That is the expression for V at time t. I hope I was able to help. Have a good day.
