Answer:
40 students
Step-by-step explanation:
We do not count the counselors or the principal because they are not students, so we do 83 - 3 = 80, now it is just simple division, for every student there is a parent, so we divide 80 in half, 80 / 2 = 40 students :D
Answer:
centre of dilation = origin (0,0)
scale factor = 3
Step-by-step explanation:
<em>In order to figure out the scale factor you just have to realise when you do a dilation, the distance between corresponding points will change according to the scale factor.</em>
By looking at the triangle B in the graph the height is 3 units
similarly corresponding height of triangleA is 1 unit
For an dilation = large number ÷ small number
So our scale factor right over here is 3.
In order to identify centre of dilation draw a straight line from end point of height of small and large triangle and make a triangle out of this.
That straight line will be hypotenuse of the triangle and it will be exactly as large as the triangle B.
