3 1/3 feet are cut off a board that is 12 1/4 feet long. How long is the remaining

Step-by-step explanation:

In order to answer this question you will have to subtract 3 1/3 from 12 1/4 by turning the mixed fractions into improper fractions, finding the common denominator, (CD) then subtracting the numerators.

Turn the mixed fractions into improper fractions:

Find the common denominator:

Now subtract the numerators:

Turn the improper fraction into a mixed fraction:

Hope this helps.

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

a)(x-2)^2+(y-1)^2=9
