An electrician has a wire 6 meters long. she needs to cut it into 12 equal pieces. how many centimeters long will each piece be? a. 2 b. 50 c. 72 d. 7,200

For this case, we must say how much each piece of cable measures, by dividing the original cable into 12 equal pieces.

So:

Thus, each piece will be 0.5 meters long, after having been cut.

Knowing that:

1 meter equals 100 centimeters, we make the following rule of three:

1 m --------------> 100 cm

0.5 m ------------> x

Thus, each piece will have 50 centimeters.

Option B

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.
