Instead of building the enclosure of maximum area, the company wishes to build only a 20,000 square foot enclosure still using u
nignag [31]

Answer:

x  =  80000/L    f

Step-by-step explanation:

When using only three sides for fencing a rectangular area, sides will be

"x "  and   "y "      x = 2*y      x  is the largest side of the rectangular area

                                             we only fence one y side ( the other side is a river

So the perimeter is  L = x  + 2*y      or   L = 4*y

On the other hand if now the area will be 20000 f²

A = x*y = 20000       ⇒    y  =  20000/ x

As the fence material is the same as that of the maximum area

L =  4*y          L = 4* 20000 / x

L*x = 80000

Then   x  =  80000/L

Where L is the quantity of fencing material

PLEASE ANSWER!!! WILL MARK BRAINLIEST!!!!!!!!
tia_tia [17]

Let 'x' represent the total distance from point A to point B

During the first hour he gets 0.25 of the way there: 0.25x

During the second hour he covers an additional 0.2 of the distance: 0.2x

During the third hour, he covers 0.3 of the distance: 0.3x

The total distance the biker traveled is:

0.25x + 0.2x + 0.3x = (0.25 + 0.2 + 0.3)x = 0.75x

The biker has: x - 0.75x = (1 - 0.75)x = 0.25x of the total distance left to go.
