In a class of 25 students, 40% say that they prefer chocolate ice cream to vanilla ice cream. which of the following proportions could be used to find how many students do not prefer chocolate? show how you got your answer. there's a lot of trolls here giving out false answers. a. 40/100 = x/25 b. 60/100 = 25/x c. 60/100 = x/25 d. 25/100 = x/40

A- 40/100 = x/25

I know this because 40% out of 100 and x/25 are how many students will get it.

If you are given only endpoints of a radius of a circle, then you need to figure out which of the given point is the center of the circle. this is probably given to you, otherwise you might have to choose one.next is to figure out the length of the radius. this is done via the distance formula.the distance between two points  and  is given by    the distance between the end points will therefore be the radius of the circle.then, use the standard equation of  a circle.for a circle centered at  with a radius of  , the equation is    where  you get from the distance formula.
