X = premium seats
y = regular seats
You need two equations: (x + y - 10 = 1200) and (30x + 20y = 30,180)
1.) Isolate one variable
y = 1,210 - x
2.) Plug the new equation into the second ORIGINAL equation
30x +20(1,210 - x) = 30,180
3.) Ditribute
30x + 24,200 - 20x = 30,180
4.) Add like terms
10x + 24,200 = 30,180
5.) Subtract 24,000 from either side
10x = 6,180
6.) Solve for x
x = 618
7.) Plug in x to the equation of your choosing
618 + y - 10 = 1200
8.) Solve for y
608 + y = 1,200
y = 592
The theater sold 592 regular seats and 618 premium seats.
Answer:
Solution given:
p=6in
b=8in
By using Pythagoras law
diameter=
=10in
r=5in
Now
Area of shaded region=area of semi circle- area of triangle
=½(πr²)-½p*b
=½(π×5²)-½(6*8)
=15.269
=15.3in² is a required answer.
15 has 1,3,5,15
18 has 1,2,3,6,9,18
12 has 1,2,3,4,6,12
Hello! So in order to find the annual growth rate, we have to divide the percentage by the number of years. 2004 and 2010 poses a gap of 6 years. We would have to set it up as 4/6. When you divide them, you would get 0.666 or 0.67 when rounded to the nearest hundredth. The average annual growth rate is about 0.67%.
