Answer:
- 160 ft (out from the river)
- 320 ft (parallel to the river)
Step-by-step explanation:
Let x represent the length of fence parallel to the river. Then the dimension of perpendicular to the river will be half the remaining fence: (640-x)/2. The total area will be ...
A = x(640-x)/2
This is the equation of a parabola that opens downward. It has zeros at x=0 and x=640, so its axis of symmetry is x = (0+640)/2 = 320. That is, the peak of the area curve is found when x=320.
The dimensions of the garden with the largest area are 160 ft wide by 320 ft long, where the long side is the river side.
Answer:
6:19
Step-by-step explanation:
There are 120 men and 380 women.
The ratio of women to men in the show is 120:380.
Simplify 120:380.
⇒ 6:19

Answer:
15.1
Step-by-step explanation:
We know that the area of the circle is 
, but we are looking for the portion of the circle, this means we multiply it by the portion of the circle that is shaded.
Area of shaded region = 
where r = 4 and x = 108, the 360 comes from the fact that the total degrees around the circle is 360, so dividing the total amount of degrees by the angle will give us the portion we are looking for.
Area of shaded region = 
= 15.1
Another way to think about it is that the area of the total circle is , multiplying it by a fraction, a number less than 1, would give us a smaller value.
Hope this helps.
