The answer is A Ted is 15 years old, and Ed is 22 years old
Namely, what is 11.65 in percentage from 24.9
if we take 24.9 to be the 100%, let's see
solve for "x".
The ratio of all marbles to the blue marbles is 1:3. There is a 33.3% chance that the next marble will be blue.
You can start by constructing a square, drawing the two diagonals and draw a circle from the centre point through the corners.
Or you could start with a circle, draw a diameter, construct a second diameter perpendicular to the first and connect the four circle points to form a square.
I think the question asks for the second method but both give a valid final diagram.
First of all, vertices is spelled like I did here, not like it is spelled in the problem.
Since it's a reflection over the vertical axis, all x-coordinates become their additive inverses.
Point (1, 0) becomes (-1, 0).
Point (2, 5) becomes (-2, 5).
Point (-1, 5) becomes (1, 5).
