Question

figure a is a scale image of figure b the scale image that maps figure a onto figure b is 1:7 1/4 enter the value of x

Answer 1

Answer:
`x=21.75`

Explanation:

You need to convert from mixed number to decimal number.

In order to do this, you can follow the steps shown below:

1. You must divide the numerator of the fraction by the denominator of the fraction.

2. Now you must add the quotient obtained to the Whole number part.

Then, you get:

`7(1)/(4)=7+0.25=7.25`

Then, the scale image that maps "Figure A" onto "Figure B" is:

`1:7.25`

Finally, in order to find the value of "x", you need to multiply the given length of the corresponding side of "Figure A" by
`7.25`.

Therefore, the result is:

`x=(3)(7.25)\\\\x=21.75`
