Answer:

C

Step-by-step explanation:

Girls - 28-12 = 16

16:12 = 4:3 - so answer choice C

We know that out of the 28 students 12 of them are boys. To find how many girls there are subtract 12 from 28

28 - 12 = 16

That means that there are 16 girls in the class

Now you need a ratio of girls : boys so...

16 : 12

This can be further simplified to the following...

4 : 3 (C)

This means that for every four girls there are 3 boys

Hope this helped!

if you draw 35 lines on a piece of paper so that no two lines are parallel to each other and no three lines are concurrent, how
Levart [38]

Answer:

The lines will intersect 595 times.

Step-by-step explanation:

We can do it in 2 methods.

<u>1st method:-</u> Let us count the number of intersections by drawing lines one by one.

1st line - 0 points=0

2nd line- new 1 point=1

3rd line - old 1 point + new 2 points with two old lines = 1+2

4th line - old (1+2) points+ new 3 points= 1+2+3

5th line - old (1+2+3) points + new 4 points=1+2+3+4

Like that from 35th line-1+2+3+4......34 = \frac{34X35}{2}=595

<u>2nd method:-</u>

We have to choose 2 lines from 35 lines.

We can do it in 35_{C} _{2} ways = 595 points
