The total number of people that all the cars can hold is greater than 480 and less than 500 people.
A: According to the given situation, where both the number of trolley cars and the number of people in each car must have two digits and be less than 30.
Hence, the possible number of trolley cars in the park = 22 and a possible number of people in each car= 22
B: explain how you found your answer.
Lets suppose the number of cars be =c and the number of persons be= p
As the number of cars and number of person are same, so c=p
so, 
should lie the given range of 480 to 500.
Now, the nearest perfect square that lies between 480 and 500 is 484.
The square root of 484 is 22. So, the number of cars and people are 22.
C: This is the only hit and trial method for solving this question.

Answer:
Step-by-step explanation:
This is a special right triangle that has 30, 60 and 90 degress corners. Because it is a special triangle, it also has side length values which always consistent relationship with one another.
Side opposite the 30° angle: x
Side opposite the 90° angle: 2x
So, 
Then use Pythagorean theorem. 
Answer:
x + 4y ≤ 15; y ≥ 0
Step-by-step explanation:
The graph doesn't do a very good job of modeling any of the given equations. However, the equations listed above seem the best fit.
The slope of the top (left) line is negative, so the equation will be of the form ...
x + 4y = something
When y=0, x=15, so the "something" is expected to be 15.
However, the line appears to go through points (6, 2) and (-2, 4). Both of these points are on the line x + 4y = 14.
The graph is shaded <em>below the line</em> so the values of x and y that are in the shaded area will add to <em>less than</em> 15 (or 14). Hence, the inequality will be ...
x + 4y ≤ something . . . . . part of the 3rd answer choice
The fact that the shading does not go below y=0 means the other limit is ...
y ≥ 0 . . . . . part of every answer choice.
