Answer:
4
Step-by-step explanation:
It takes 4 hours to do task E using the route: start ⇒B⇒E
It will take 6 hours to do task E if using route : start ⇒C ⇒E
Taking the shortest route, it will take 4 hours
You can apply the critical path method to identify the shortest route possible. First , specify the activity and look for their dependencies.Using the activity diagram, establish the activity completion time.Finally, identify the critical path using the best case estimate.
Answer:
18 gallons containing 20% solvent and 6 gallons containing 60% solvent
Step-by-step explanation:
the painter needs 24 gallons of paint containing 30% solvent = 7.2 gallons of solvent
let a = 20% solvent paint
let b = 60% solvent paint
a + b = 24
0.2a + 0.6b = 7.2
(replace a = 24 - b in the second equation)
a + b = 24
0.2(24 - b) + 0.6b = 7.2
4.8 - 0.2b + 0.6b = 7.2
0.4b = 7.2 - 4.8 = 2.4
b = 2.4 / 0.4 = 6
a = 24 - 6 = 18
