Four individuals pool money together to start a new business and agree to split the profits equally. N invests $6,000, X invests
shepuryov [24]

Answer:

15,000$

Step-by-step explanation:

According to the information given, profits are divided equally into 4 parts

Since the total profit for the first month is 100,000$ each party will receive a sum of 25,000$. This means that Y also receives the same amount

Now if the profits were divided in proportion to the investments made we first find the proportion on investment made by Y.

The total investment made is 6000$ + 2000$ + 8000$ + 4000$ = 20,000$. Out of this, the amount invested by Y is 8000$

finding the proportional profit of Y

\frac{8000}{20000} (100000)

=40,000$

So Y receives 40,000 - 25,000 = 15,000 less

Sand falls onto a conical pile at the rate of 10 cubic feet per minute. The radius of the pile is always equal to one half it al
Andreas93 [3]

Answer:

Either one of these.

Step-by-step explanation:

volumepile=1/3 (PI r^2)h

but r=h/2, so

volume=1/12 PI h^3

dv/dt=10 ft^3/min

but dv/dt=1/12 PI 3h^2 dh/dt

solve for dh/dt

This assumes you mean by "altitude" the height. If you mean altitude as slant height, you have to adjust the fromula

_______________________________________________

given: r = h/2

V = (1/3)π r^2 h

= (1/3)π (h/2)^2 (h)

= (1/12) π h^3

dV/dt = (1/4)π h^2 dh/dt

for the given data ...

10 = (1/4)π(25)dh/dt

dh/dt = 10(4)/((25π) = 1.6/π feet/min
