The graph shows how many bottles a machine fills in a certain number of seconds: Choose one ordered pair on the graph. What does it represent in this situation?

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.

17

step-by-step explanation:

51/3=17

thus 17 is your answer.
