A scale factor is a number that u multiply one set of points by to get to the other set...

(3,9)....to (1.2,3.6)

so what are we gonna multiply 3 by to get to 1.2 ? And what are we gonna multiply 9 by to get to 3.6 ? It should be the same number

3x = 1.2          9x = 3.6
x = 1.2/3          x = 3.6 / 9
x = 0.4            x = 0.4

so 3 * 0.4 = 1.2
and 9 * 0.4 = 3.6

so ur scale factor is 0.4 or 2/5

6/54 times because there are 9 marbles and the orange marble is 1 out of those 9 marbles. If you multiply 6*9= 54 then you notice there is a 6/54 chance of picking any 1 marble out of the 54 times that you decide to pick marbles.

Nuetrik [128]

9514 1404 393

Answer:

  x= 10, corresponding

Step-by-step explanation:

Corresponding angles are in the same direction from their respective intersections. Here, the angles are both northwest of the point where the lines cross. The angles are corresponding.

__

Corresponding angles are congruent, so we have ...

  10x +10 = 110

  10x = 100 . . . . . subtract 10

  x = 10 . . . . . . . . divide by 10
