Answer:
B. 13 small bags and 12 large bags
Step-by-step explanation:
This question can be solved using a system of equations.
I am going to say that:
x is the number of small bags.
y is the number of large bags.
The Tuesday morning delivery consists of 25 bags
This means that , that is
Bunyan Farm sells 3 pound and 5 pound bags of onions. Total of 99 pounds.
This means that
Since
So 13 small bags and 12 large bags.
The time it will take the tank to be empty is;
<em><u>t = 1.26 minutes</u></em>
The image of the initial tank is missing and so i have attached it.
Let's call the area of the hole be A_h
- From conservation of energy, velocity at which water leaves the tank is; v = √2gh
Thus, volumetric rate; = A_h(√2gh)
- If we consider possible friction and contraction, we differentiate to get;
dV/dt = -cA_h(√2gh)
Now, volume of tank is;
V = ¹/₃πr²h
V' = dv/dt = (¹/₃πr²h)dh/dt
Thus; -cA_h(√2gh) = (¹/₃πr²h)dh/dt
- Integrating to get t gives us;
t = (2(√H - √h))/(3c√2g × (r'/r)²)
where;
r' is radius of circular hole = 4 inches = 0.333 ft
h = 0 since the tank has a hole
c = 0.6
g = 32 ft/s²
H = 8 ft
- Since the vertex has an angle of 60°, then a line of symmetry across it divides the angle into two which will be 30° each. We can use trigonometry to find the current radius r.
Thus; r/H = tan 30°
r = 8 tan 30°
r = 4.6188 ft
Thus;
t = (2(√8 - √0))/(3 × 0.6(√2 × 32) × (0.333/4.6188)²)
t = 75.5757 seconds
Converting to minutes gives; t = 1.26 minutes
