Area=length*width
let the sides perpendicular to the river be x
then the side parallel to the river is 4,700-2x
A(x)=x(4700-2x)
A(x)=4700x-2x^2
This a quadratic function with a=-2 and b=4700
thus
Maximum area occurs where x=-b/2a=-4700(-2*2)=1,175 ft
length=4700-2(1175)=2,350 ft
Answer:
Nika can make 15 cups of milk.
Step-by-step explanation:
To find how many cups she can make, we divide 3 3/4 by 1/4. First, we convert 3 3/4 to an improper fraction.
3 ¾ / ¼ Equation
15/4 / ¼ Convert to improper
15/4 * 4/1 Reverse sign & second fraction
= 60/4
= 15
Also, 15 * 1/4 = 3 ¾, so its correct!
