Answer:
42%
Step-by-step explanation:
1) so out of the 50 girls surveyed, only 21 students played in the league. We can write this as 21/50
to convert this into percentage multiply by 2 on both sides:
21*2=42
50*2=100
42/100=42%
42% of girls played in the league
hope this helps!
150(number of tissues)*20(length of tissues) = 3000cm.(total length)
Then to convert it to meters...
1 meter = 100 cm.
3000 ÷ 100 = 30
So 30 meters of paper is needed.
Does that help?
It will take 100 weeks to build the tower.
Since Donald Trump wants to build a 100 meter high tower as quickly as possible with blocks that are 100 meters long and 100 meters wide, but only 1 meter tall, and using special lifters, putting one stack on top of another stack takes one week regardless of how high the stacks are, to determine what is the shortest amount of time (weeks) that it will take to build the tower, the following calculation must be performed:
- Time per block x total blocks = Total time
- 1 week x 100 = X
- 100 weeks = X
Therefore, it will take 100 weeks to build the tower.

well, is noteworthy that an x-intercept is when y = 0 or namely is a solution or root of the quadratic, so we know then that the x-intercepts or solutions are at (-1,0) and (3,0), that simply means that
