Answer:
11
Step-by-step explanation:
organize it:
10, 10, 11, 11, 11, 11, 12, 12, 13
the number in the middle of the order is the median, in this case the median would be 11.
12+28+40+12=52
Perimiter =52ft
Yards=3 feet
52ft/3 is about 17.34yards
Now multiply yards by cost
17.34 x 15=260$
It costs 260 for titles to be put around the pool

Answer:
x+y= 120
90x+250y=27,600
Step-by-step explanation:
x= number of certain tickets
y= number of remaining tickets
The statement indicates that for a particular flight the airline sold 120 tickets which means that the sum of the different tickets is 120. The first equation is:
x+y= 120
Then, the statement says that certain number of tickets costs $90 and the remaining tickets cost $250 and that for a particular flight, the airline collected $27,600. From this, you can say that the number of certain tickets, x, multiply for its price that is $90 plus the number of the remaining tickets, y, multiply for its price that is $250 would be equal to $27,600. The equation would be:
90x+250y=27,600
According to this, the answer is that the system of equations that represents this relationship between x and y is:
x+y= 120
90x+250y=27,600
