Answer:c
Step-by-step explanation:
Answer:
Width=20 feet
Since Length=Width=20 feet, the rectangle is a Square.
Step-by-step explanation:
Area,
To determine the width of the rectangle that gives the maximum area, we take the derivative of A and solve for its critical point.
The width of the rectangle that gives the maximum area =20 feet.
Perimeter of a rectangle=2(l+w)
Perimeter of the rectangle=80 feet
2(l+w)=80
2l+2(20)=80
2l=80-40
2l=40
l=20 feet
Since the length and width are equal, the special type of rectangle that produces this maximum area is a Square.
Answer:
2500 meals in 20 hours.
Step-by-step explanation:
The easiest point to see is (2,250). The other point (since you need 2) is the origin. This is a graph. It does not require any greater accuracy than looking at the point that is chosen.
x = 2
y = 250
k = ?
y = k*x equation
250 total meals packed = k * 2 hours Substitute values
k = 250 /2
k = 125 meals / hour
Let x = 20 hours
k = 125 meals / hour
y = ?
y = 125 * 20
y = 2500 meals
Answer:
n=3
Step-by-step explanation:
n/45=1/45
cross multiplying
15n=45
n=45/15
n=3
