15DANCE TICKETS WERE SOLD IN ONE HALF HOUR. IF THIS RATE CONTINUES HOW LONG WOULD YOU EXPECT IT TO TAKE TO SELL 270 tickets.

Mathematics
1 answer:
Oliga [24]3 years ago

Answer:

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:

\frac{tickets}{time}=\frac{15}{0.5}=\frac{270}{x}

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

Find the value of x.
aleksandr82 [10.1K]

the sum of all interior angles in a polygon is

180( n - 2)

n = number of sides

now, this polygon is a quadrilateral, so it has 4 sides, so it's total is just 180( 4 - 2) = 360.

360=x+4x+3x+2x\implies 360=10x\implies \cfrac{360}{10}=x\implies 36=x
