I need this question done thanks

H. 40%

Step-by-step explanation:

18/30 = 60%

So 60% of kids have last names with more than 8 letters.

That means 40% of kids have last names with fewer than 8 letters.

(Because the percentages have to add up to 100)

Hope this helps! :)

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
