Figure b is a scaled copy of figure a. what is the scale factor from figure a to figure b?

The scale factor from Figure A to Figure B is 0.5

since the scale factor is less than 1 so the figure is contracted.

Given there are two figures of rectangles

Figure A and figure B

We are asked the scale factor from figure A to figure B

Hence the final figure is figure B and the initial figure is Figure A

The scale factor of any figure is defined as formulated in equation (1)

According to the given figures we can observe that

Length of pair of  one  parallel  sides of figure A is drawn using 4 squares while the same for figure B uses only 2 squares.

So from the equation (1) we can write that

So the scale factor from Figure A to Figure B is 0.5

since the scale factor is less than 1 so the figure is contracted.

The scale factor from Figure A to Figure B is

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is the scale factor

Let

z-----> the scale factor

In this problem

substitute values

the scale factor is less than 1

therefore

is a reduction

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
