Question

A scale factor of 3.5 maps Figure A onto Figure B. There is two triangles, Figure A is 5, Figure B is x. Whats the value of X?

Answer 1

17.5

Explanation:

Answer 2

X = 17.5

Explanation:

Here we have a word problem relating to syntax regarding mapping of a scale factor;

Whereby the scale factor is 3.5 we have that the scale factor can be represented as 2:7

Hence the scale is for every 2 units of Figure A, we have 7 units of Figure B

Hence where Figure A is 5, we have;

2 unit of Figure A = 7 units of Figure B

∴ 1 unit of Figure A = 7/2 (=3.5) units of Figure B

5 unit of Figure A = 3.5 × 5 units of Figure B = 17.5 units of Figure B

Therefore where we have;

5 unit of Figure A = X units of Figure B

Then, X = 17.5.
