15dance tickets were sold in one half hour. if this rate continues how long would you expect it to take to sell 270 tickets.

9 hours

Step-by-step explanation:

Using the initial ratio of 15 tickets in half an hour, you can set up a proportion (equivalent ratios) to find the amount of time it would take to sell 270 tickets:

Where 'x' is the amount of time to seel 270 tickets.

Cross-multiply: 0.5(270) = 15x or 135 = 15x

Divide: 15x/15 = 135/15 or x = 9 hours

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
