Answer:
Writing a number in standard form simply means to express the number in its 'normal' form. Therefore, your example is written in standard form.
210 possibilities, if I am not mistaken.
I did a tree diagram. You first name the seven skaters (skater 1, skater 2, skater 3, ect..) and write them in a row.
After you do that, do 6 arrows from each number because you cannot have skater 1 be first and second place, same with 2 and 3 and so on, so you need only 6 arrows. Make sure when you label the arrows that none of the arrows are labeled as the first skater number you drew in the beginning.
Finally, from each arrow you just drew, draw 5 arrows labeled each skater EXCEPT the skater you drew in the beginning and the second skater.
To save time, you could just do all of the steps above for only one beginning skater. You don't have to do it to all of them, you would run out of paper and it would be super messy.
Count all of the outside arrows. You should have 30. Then, since there are 7 skaters and you did only one, do 30x7, which gives you the total outcomes of 210 possibilities.
Answer:
The number of child tickets sold was 43 and the number of adult tickets sold was 20
Step-by-step explanation:
Let
x ----> the number of child tickets sold
y ----> the number of adult tickets sold
we know that
-----> equation A
----> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
The solution is the point (43,20)
see the attached figure
therefore
The number of child tickets sold was 43 and the number of adult tickets sold was 20
1/4 or .25 or 25%
You basically just divide 60 by 15. So 15 goes into 60 4 times. Therefore, 4 is our denominator with one as our numerator.
