Answer:
30 ft
Step-by-step explanation:
We can use the given information to set up a ratio...


We can solve this ratio using cross multiplication (multiply the numerator of the first fraction by the denominator of the second and the numerator of the second fraction by the denominator of the first):
120 = 4x
Divide both sides by 4
x=30 ft
1/2 for a coin. 1/6 for a die. multiply them and u get 1/12 (you happy now weirkai27?) 1/12 is your answer.

The maximum number of turning points in a cubic function is 2.
In this case,

The discriminant is

, which means the derivative has no real roots. This means there are no critical points and thus no turning points/relative extrema.
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.
