Answer:
0.50n+25=27.50
Step-by-step explanation:
you can ride 5 rides, aka n=5
2(2x + 9) + 2(x) = 36
4x + 18 + 2x = 36
Combine like terms.
6x + 18 = 36
Subtract 18 from both sides.
6x = 18
Divide 6 on both sides.
x = 3
Hope this helps!
Answer:
dy/dt = - (1/5) ft/s = - 0.2 ft/s
Step-by-step explanation:
Given
L = 5 ft
Qin = 25 ft³/s
Qout = 30 ft³/s
h = 10 ft
dy/dt = ?
We can apply the relation
ΔQ = Qint - Qout = 25 ft³/s - 30 ft³/s
⇒ ΔQ = - 5 ft³/s
Then we use the formula
Q = v*A
where Q = ΔQ, A = L² is the area of square base and v = dy/dt is the rate of change in the depth of the solution in the tank
⇒ ΔQ = (dy/dt)*L²
⇒ dy/dt = ΔQ/L²
⇒ dy/dt = (- 5 ft³/s)/(5 ft)²
⇒ dy/dt = - (1/5) ft/s = - 0.2 ft/s
Heeelllllloooooo! :D
Okay this is a very similar question to the one I answered earlier....
I'll show you step by step so you will be able to do this in the future on your own
(y - y₁) = m(x - x₁) -----> point-slope form
(y + 6) = (-0.38)(x - 5)
y + 6 = -0.38x + 1.9
<u>y = -0.38x - 4.1</u><u />
There you go!
