Answer:
A = (100 - y)y
Maximum area = 2500 sq. feet.
Step-by-step explanation:
Let the length of the combined rectangular area is y feet and the shared width is x feet.
So, perimeter of the two rectangle together is (3x + 2y) = 200 {Given}
⇒ 2y = 200 - 3x
⇒
...... (1).
a) Now, area of the total plot in sq. feet is
........ (2)
So, this is the expression for area A in terms of length of shared side x.
b) For area to be maximum the condition is 
Now, differentiating equation (2) on both sides with respect to x we get

⇒ x = 33.33 feet.
So, from equation (1) we get 
⇒ x = 50 feet.
So, the value of maximum area = 50 × 33.33 = 1666.5 sq. feet. (Answer)
Answer:1:4:3
Step-by-step explanation:
Divide through by what is most common to them and that is 3.
The simplest form will be 1:4:3
No, False. All seats in row 1 are same viewing angle. They are inscribed angles measuring 90 degrees. All the seats on row 1 will have the exact same viewing angle because they form a semi-circle around the stage. these would be inscribed angles that have the endpoints of the stage. They would all be 90-degree agles because the stage creates a semicircle and the endpoints of the stage are all the same.
