32 students would be on the trip. What I did to solve it was a proportion. 8students/ 3 chaperones= x students/12 chaperones.
8*12= 96 and 96/3=32. Therefore 32 students were on the trip.
24:16 in simplest form, is.... 3:2 3 to 2
This solution to this problem is predicated on the fact that the circumference is just:
. A straight line going through the center of the garden would actually be the diameter, which is well known to be two times the radius of the circle, so we can say that the circumference is just:

So, solving for both the radius and the diameter gives us:

So, the length of thes traight path that goes through the center of the guardain is just
, and we can use the radius for the next part of the problem.
The area of a circle is
, which means we can just plug in the radius and find our area:

So, we have found our area(
) and the problem is done.
To find the m(slope) of our graph we can take two points from the graph, im going to use (0,2) and (1,8) the formula for slope is y2-y1/x2-x1
Plug the points in to get 8-2/1-0
The slope of this equation is 6.
For the y-intercept we just find where the line meets the y-axis and that is at 2.
The equation for this graph is y=6x+2
