Answer:
2
Step-by-step explanation:
Slope or gradient of a line is given by dividing change in y axis by the change in x axis. Slope is represented by m hence 
where 
is the change in y axis while 
is the change in x co-ordinates. Substituting with 6 units while 3 units substitute then the slope will be 
Therefore, the gradient is 2
5x + 4y = 32 ⇒ 45x + 36y = 288
9x - 1y = 33 ⇒ <u>45x - 5y = 165</u>
<u>41y</u> = <u>123</u>
41 41
y = 3
5x + 4(3) = 32
5x + 12 = 32
<u> - 12 - 12</u>
<u>5x</u> = <u>20</u>
5 5
x = 4
(x, y) = (4, 3)
Answer: 6 Containers are needed
Step-by-step explanation:
The ideal number of Kanban cards can be calculated using the following formula;
N = (DT × ( 1 + X)) / C
where N is total number of container,
D is panned usage rate of using work Centre
T is Average waiting time for replenishment of parts plus average production for a container of parts,
X is policy variable set by management that reflects possible inefficiency in the system ,
C is capacity of standard container.
Now, given that;
D = 105 parts
T = 90min = 90/60 = 1.5 hrs
X = 0.35
C = 3 × 12parts = 36 parts
so; we substitute
N = (105×1.5 × ( 1 + 0.35)) / 36
N = 212.626 / 36
N = 5.9063 ≈ 6
Therefore 6 Containers are needed
