Answer:
649 trains
Step-by-step explanation:
If there are 30 seats per carriage, and there is 18 carriages per train.
You multiple 30 and 18 to get how many seats there are in a train.
30*18 is 540 seats.
To figure out how many trains would be needed to seat 350,000 passenger, you have to divide 350,000 with 540 to get how many trains would be needed.
350,000/540 is 648.1
Since the answer is 648.1 and you can't chop a train into 10 pieces, you would need 649 trains to seat 350, 000 passengers.
30 times as many students than teachers
Equation = 450/30 = 15 teachers

Answer:
The arc PR is 
Step-by-step explanation:
A descriptive diagram of the diagram given in the question is shown on the first uploaded image
In the circle tangent
, secant
and chord
are drawn
given that
,
The objective is to determine PR
From the diagram we see that MQ is a straight which implies that the the angle


Now looking at triangle NMP we see that
Now the measure of an inscribed angle is half the measure of its arc intercepted, this statement is the inscribed angle theorem
So with the knowledge
Then

Looking at the diagram we see that
