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
Answer:
10
Step-by-step explanation:
You are doing:
(2/5) * 25
You can do it two ways, first divide, then multiply, OR multiply, then divide.
In this case, I will multiply, then divide:
First, multiply:
(2 * 25)/5 = (50)/5
Next, divide:
50/5 = 10
10 is your answer.

D=62*
triangles=180*
use the equation 90+28+d=180
The equation for line E is x = 8.
This is because the line intersects the x-axis at the point (8,0)
Answer:
i can only explain it. sorry. if u need help ask
Step-by-step explanation:
so u gotta find a, b, and c.
the first part of a is going to equal x, the other is y(u know what i mean?)
so it says that a= -2, -1. So -2 is the x and -1 is the y.
y= rise/run.
thex=run, and the rise =y.
