The right answer is “The classroom has 5,180 seats “
Answer:
Step-by-step explanation:
Let the other side of the rectangle be y. The perimeter of the rectangle is expressed as P = 2(x+y)
Given P = 30ft, on substituting P = 30 into the expression;
30 = 2(x+y)
x+y = 15
y = 15-x
Also since the area of the rectangle is xy;
A = xy
Substitute y = 15-x into the area;
A = x(15-x)
A = 15x-x²
The function that models its area A in terms of the length x of one of its sides is A = 15x-x²
The side of length x yields the greatest area when dA/dx = 0
dA/dx = 15-2x
15-2x = 0
-2x = -15
x = -15/-2
x = 7.5 ft
Hence the side length, x that yields the greatest area is 7.5ft.
Since y = 15-x
y = 15-7.5
y = 7.5
Area of the rectangle = 7.5*7.5
Area of the rectangle = 56.25ft²

Step-by-step explanation:
16 < 22 - 8 = 22
16 < 14 = 22
This question doesnt make sense, not only is the inequality false, but the equation isn't equal either.
Answer:
2854.54 in^3
Step-by-step explanation:
since volume of a sphere is: V= 4/3 x π x r^3, and the radius is 8.8 in, you just multiply 4/3 x π x (8.8)^3.
