A farmer has 520 feet of fencing to construct a rectangular pen up against the straight side of a barn, using the barn for one s
Setler [38]

Answer:

310\text{ feet and }210\text{ feet}

Step-by-step explanation:

GIVEN: A farmer has 520 \text{ feet} of fencing to construct a rectangular pen up against the straight side of a barn, using the barn for one side of the pen. The length of the barn is 310 \text{ feet}.

TO FIND: Determine the dimensions of the rectangle of maximum area that can be enclosed under these conditions.

SOLUTION:

Let the length of rectangle be x and y

perimeter of rectangular pen =2(x+y)=520\text{ feet}

                                                x+y=260

                                               y=260-x

area of rectangular pen =\text{length}\times\text{width}

                                       =xy

putting value of y

=x(260-x)

=260x-x^2

to maximize \frac{d \text{(area)}}{dx}=0

260-2x=0

x=130\text{ feet}

y=390\text{ feet}

but the dimensions must be lesser or equal to than that of barn.

therefore maximum length rectangular pen =310\text{ feet}

                              width of rectangular pen =210\text{ feet}

Maximum area of rectangular pen =310\times210=65100\text{ feet}^2

Hence maximum area of rectangular pen is 65100\text{ feet}^2 and dimensions are 310\text{ feet and }210\text{ feet}

d1i1m1o1n [39]

Answer: A.4Runner cost more for $11.02

              B.Cost of fuel for Elentra: 3.75*3.59=$13.46

                 Cost of fuel for 4Runner : 6.818*3.59=$24.48

Step-by-step explanation:

A.Find how many gallons 4Runner spends on 150 mile trip.

use proportion

22:1=150:x

22x=150

x=150/22

x=6.818 gallons  

Cost of fuel for 4Runner : 6.818*3.59=$24.48

Calculation for Elentra:

40:1=150:x

40x=150

x=150/40

x=3.75 gallons

Cost of fuel for Elentra: 3.75*3.59=$13.46

Cost of fule for 4Runner-Cost of fuel for Elentra=24.48-13.46=$11.02

4Runner cost more for $11.02

B.Cost of fuel for Elentra: 3.75*3.59=$13.46

Cost of fuel for 4Runner : 6.818*3.59=$24.48
