Answer:
<h3>37.5m/s</h3>
Step-by-step explanation:
If a coal train in Montana starts from rest and accelerates at 2.5 m/s2 for 15s,let us calculate the final velocity of the train.
Use the equation of motion v = u + at where;
v is the final velocity
u is the initial velocity = 0m/s (starts from rest)
a is the acceleration = 2.5m/s²
t is the time = 15secs
Substituting the given parameters into the formula;
v = 0+(2.5)(15)
v = 0+37.5
v = 37.5m/s
Hence the final velocity of the train is 37.5m/s
First we have to determine how many people fir in each section.
Since these sections are evenly distributed, each section has a third of the capacity, thus= 15,000/3 = 5000 persons per section.
Now we determine revenue by section by multiplying times the ticket price.
5,000 * $10.00 = $50,000
5,000 * $12.50 = $62,500
5,000 * $15.00 = $75,000
We add up the totals for $187,500 and that's the answer!
By direct correspondence AB = PQ
Since ABCD is a quadrilateral,
We know that sum of the interior angles of any quadrilateral =360
=>A+B+C+D=360
=>2x+90+x +3x=360
=>6x+90=360
=>6x=360-90
=>6x=270
=>x =270/6
=>x =45
Answer:
I believe A has the proper quartiles and the approx median marked correctly
