If a stadium has 30,000 seats and tickets are sold at $55 each what percentages of tickets were unsold if the total ticket sales for the game was 1,485,000?

10%

Step-by-step explanation:

First, find how many tickets were sold

1485000/55=27000

Then, divide how many tickets were sold by how many seats there are

27,000/30,000=0.9

So, 90% of the tickets sold, and 10% did not sell, so choice 1 is your answer.

Hope this helped!

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
