Total of 49 1/4 + 3 3/8

Ede4ka [16]

49*4=196+1=197/4
8*3=24+3=27/8 

then make the denominator the same
multiply 197*2 and 4*2 = 394/8 
then 394/8 +27/8 =421/8 
u can either leave it here or in decimal form which would be 52.625 or in mixed numbers-52 5/8

Figure AAA is a scale image of Figure BBB. What is the value of xxx?

Arada [10]

Answer:

The scale factor from Figure A to Figure B is 1/2

Step-by-step explanation:

The correct question is

Figure B is a scaled copy of Figure A.

What is the scale factor from Figure A to Figure B?

The picture in the attached figure

we know that

A dilation is a non rigid transformation that produce similar figures

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

In this problem Figure A and Figure B are similar

To find out the scale factor, determine the ratio of its vertical corresponding sides

The vertical side of figure A is 4 units

The corresponding side in figure B is 2 units

$\frac{2}{4}=\frac{1}{2}$

The scale factor is less than 1

The dilation is a reduction

therefore

The scale factor from Figure A to Figure B is 1/2
