Answer:
Step-by-step explanation:
If given tables in the picture show the proportional relationship,
Number of wheels (w) ∝ Number of buses (b)
w ∝ b
w = kb
Here, k = proportionality constant
k =
Number of buses (b) Number wheels (w) Wheels per bus
5 30
8 48
10 60
15 90
Here, proportionality constant is 6.
Similarly, If number of wheels (w) ∝ Number of train cars (t)
w = kt
Here, k = proportionality constant
k =
Number of train cars(t) Number of wheels(w) Wheels per train car ()
20 184
30 264
40 344
50 424
Since, ratio of w and t is not constant, relation between number of wheels and number of train cars is not proportional.
Since we have a cubic root, we're interested in factoring cubes inside the root, so that we can take them out. If we factor 648, we have
So, we have
And the result simplifies to
