Answer:
x/5 = 5280/1
Step-by-step explanation:
this is a proportion set up and then cross multiple. You will get your answer for x. Which is 26, 400 feet.
Salt flows in at a rate of (5 g/L)*(3 L/min) = 15 g/min.
Salt flows out at a rate of (x/10 g/L)*(3 L/min) = 3x/10 g/min.
So the net flow rate of salt, given by 
in grams, is governed by the differential equation,
which is linear. Move the 
term to the right side, then multiply both sides by 
:
Integrate both sides, then solve for :
Since the tank starts with 5 g of salt at time 
, we have
The time it takes for the tank to hold 20 g of salt is 
such that

Answer:
99
Step-by-step explanation:
Kruskal's Algorithm has you add edges in order increasing weight, skipping ones that create loops.
__
The order of increasing weights for this graph is ...
10, 12, 14, 16, 18, 22, 24, 25, 28
The edges that can be added without creating loops are shown in bold.
The weight of the minimum spanning tree is ...
10 +12 +14 +16 +22 +25 = 99
