How do you draw a skew line?
Bas_tet [7]
In three-dimensional geometry, skew lines are two lines that do not intersect and are not parallel. A simple example of a pair of skew lines is the pair of lines through opposite edges of a regular tetrahedron. Two lines that both lie in the same plane must either cross each other or be parallel, so skew lines can exist only in three or more dimensions. Two lines are skew if and only if they are not coplanar. Hope this helps!! :)

18/100 divided by 2/2 = 9/50
In conclusion the answer is 9/50.
Hopefully that helped! :)

Solve the inequality
worty [1.4K]

Treat it just like and equation at first. Multiply the 10 on both sides to get rid of it, leaving you with 50 \leqx.  Then on the number line, since there is a line under it, you would make a filled in circle and an arrow pointing towards 51 and beyond

In a room, there are 450 students of which 20% are girls. A group of students have mobile phones with them, of which 40% are gir
andrew-mc [135]

Answer:

216 boys

Step-by-step explanation:

450 students: 20% girls, 80% boys

450*20%=90 girls

450*80%=360 boys

Students having mobile phones: 40% (OF THE 90) girls, 60% (OF THE 360) boys

90*40%=36 girls

360*60%=216 boys

[We honestly don't need to care about the girls without mobile phones as they are only asking how many boys have mobile phones]
