Nezavi [6.7K]

i dont want to assume all the other people participating in after school activities are girls but if they are, the answer is 108.

180 = 100%

x = 40%

the information above shows that 60% are girls

60% of 180 = 108 or 0.60 x 180 = 108

the answer is 108

hope this is helpful!

Any suggestions or answers
JulsSmile [24]

Answer:

Step-by-step explanation:

Given (x - 2)^2 + (y + 3)^2 = 9, compare this to the standard equation of a circle, (x - h)^2 + (y - k)^2 = r^2.

It then becomes obvious that h = 2 and k = -3; the coordinates of the center of the circle are (2, -3).

If r^2 = 9, then r must be 3.  This is the radius of the circle.

To draw this circle:  Plot the center (2, -3).  Take a compass and open it up so that the distance between the compass points is 3, representing the radius of the circle.  Now use the compass to draw a circle with radius 3 and center at (2, -3).
