Answer:
- A: 24,500
- B: 11,800
- C: 12,700
Step-by-step explanation:
Since the number of A seats equals the total of the rest of the seats, it is half the seats in the stadium: 49000/2 = 24,500.
The revenue from those seats is, ...
24,500×$30 = $735,000
so the revenue from B and C seats is ...
$1,246,800 -735,000 = $511,800
__
We can let "b" represent the number of B seats. Then there are 24500-b seats in the C section and the revenue from those two sections is ...
24b +18(24500-b) = 511800
6b = 70,800 . . . . . . . . . . . . . . . subtract 441000, collect terms
b = 70,800/6 = 11,800 . . . . . . . seats in B section
24,500 -11,800 = 12,700 . . . . . seats in C section
There are 24500 seats in Section A, 11800 seats in Section B, and 12700 seats in Section C.
The dimensions of the coop are length = 12 ft and width = 9 ft
<h3>Area of the coop</h3>
Since the coop is a rectangle, the area of the coop is A = LW where
- L = length of coop and
- W = width of coop.
Now, the length of the coop 3 feet longer than the width, so, L = W + 3
Now, the area of the coop A = 108 ft²
So, A = LW
A = (W + 3)W
108 = W² + 3W
Re-arranging,
W² + 3W - 108 = 0
So, we solve the equation to find the width of the coop
<h3>
Width of coop</h3>
W² + 3W - 108 = 0
Factorizing, we have
W² + 12W - 9W - 108 = 0
W(W + 12) - 9(W + 12) = 0
(W + 12)(W - 9) = 0
W + 12 = 0 or W - 9 = 0
W = -12 or W = 9
Since W cannot be negative, W = 9
<h3>
Length of coop</h3>
Since L = W + 3
Substituting the value of W into L, we have
L = W + 3
L = 9 + 3
L = 12 ft
So, dimensions of the coop are length = 12 ft and width = 9 ft

The answer is 20.5 try it good luck
Here we see that the number 27 is closer to 30 than 20. Here we cannot see whether 25 is closer to 20 or to 30. If the digit following the rounding place is 0, 1, 2, 3, or 4, we round down. If the digit following the roundingplace is 5, 6, 7, 8, or 9, we round up.
You have to find the average of 38 and 42 (witch is 40) and then set it to a ratio of 40:100 multiply both sides by 8.5 and we get 340
