A rancher has 800 feet of fencing to put around a rectangular field and then subdivide the field into 3 identical smaller rectan
Fittoniya [83]

Let x be the shorter side, and y be the longer side

 

There would be 4 fences along the shorter side, and 2 fences along the longer side

4x + 2y = 800

Rewrite in terms of y:

y = 400 − 2x

 

The area of the rectangular field is

A = x*y

Replace Y with the equation above:

  A = x(400 − 2x)

  A = − 2x^2 + 400x

 

The area is a parabola that opens downward, the maximum area would occur at the parabola vertex.

At the vertex

x = −b/2a

  = −400/[2(−2)]

  = 100

 

y = 400 −2x

y = 400 -2(100)

y = 400-200

y = 200

 

The dimension of the rectangular field that maximize the enclosed area is 100 ft x 200 ft.

Lanette drove 248 miles in 4 hours. At the rate, how many hours will it take her to drive a additional 93miles.
LenaWriter [7]

Answer:

1.5 hours

Step-by-step explanation:

using the relationship between distance/ speed / time

distance = speed × time

speed = \frac{distance}{time} = \frac{248}{4} = 62 mph

travelling at this rate then

time = \frac{distance}{speed} = \frac{93}{62} = 1.5 hours
