The senior class is taking a trip to an amusement park. they received a special deal where for every 3 tickets they purchased they received 1 free ticket. 3 tickets cost $53.25. the total purchase of tickets cost $1,384.50. how many tickets did they receive?

First have to do 1,384.50 divided by 53.25= 26. They recieved 26 free tickets.
Second you would have to do 53.25 divided by 3= 17.75 then you would do 1384.50 divided by 17.75=78.  Lastly you would add 78 and 26 to get 104. 
They would recieve 104 Tickets

there are 96 wizards

step-by-step explanation:

20% of 120 is 24. if you subtract 24 from 120 you get 96

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
