Answer:
Train B is traveling faster
Step-by-step explanation:
From the picture, we want to know which train is traveling faster
We can know this by knowing the speed of the trains
Mathematically;
speed = distance/time
Train A
12.5 m in 1 second
speed = 12.5/1 = 12.5 m/s
Train B
100 m in 4 seconds
speed = 100/4 = 25 m/s
So train B is traveling faster
This is because it covered a distance of 100 m in 4 seconds as opposed to train A which covered a distance of 12.5 m
in 1 second
Answer:
Yes, it costs $18.99.
Step-by-step explanation:
The game is originally $36 and a game 50% off is 36/2 = $18.
The sale price is $18.
The state charges 5.5% tax which means you pay 105.5% of the sale price.
1.055(18) = 18.99
The final total is 18.99 which means Ron's $19 is enough.

Answer:
Number of Ways = ₄P₄ = 24
Step-by-step explanation:
Given that there are going to be 4 dignitaries, and that they are sensitive to the order (i.e the order of the dignitaries matter), hence the total number of ways they can be arranged can be found by permutating 4 dignitaries.
i.e
Number of Ways = ₄P₄ = 24
Answer:
1584 cu in.
Step-by-step explanation:
Since the volume varies jointly with the radius and height we have an equation V = kr^2h where k is the constant of variation
28 = 2^2(7)k = 28k
k = 1
Now V = r^2h
V = (12)^2(11) = 144(11) = 1584 cu in.
