Answer

20.56

Step-by-step explanation:

tan∅=opposite/adjacent

=1.5÷4

=0.375

then to get ∅ find the tan inverse of 0.375 you'll get 20.55604...

put it in two decimal point...20.56°

A rectangle that maximize the enclosed area has a length 800 yards and width is 800 yards. The maximum area is 640,000 square yards.

In the given question we have to find the maximum area of the rectangular area.

Liana has 3200 yards of fencing to enclose a rectangle.

So we know that the perimeter of rectangle is

P= 2(l+b)

Let length of the rectangle is x yards and width is y yards.

So the equation should be

2(x+y) = 3200

Divide by 2 on both side we get

x+y = 1600................(1)

As we know the area of rectangle is

A = xy

From the equation the value of y is 1600-x.

Now putting the value of y

A = x(1600-x)

A = 1600x-x^2

On differentiating

dA/dx = 1600-2x

Putting dA/dx=0

1600-2x=0

Subtract 1600 on both side we get

-2x= -1600

Divide by -2 on both side we get

x = 800 yards

Now putting the value of x in the y=1600-x

y=1600-800

y=800 yards

So the maximum area is

A= 800*800

A= 640,000 square yards

Hence, a rectangle that maximize the enclosed area has a length 800 yards and width is 800 yards. The maximum area is 640,000 square yards.

1. A company has $5826 to give out in bonuses. An amount is to be given out equally to each of the 29 employees.

pashok25 [27]

Answer:

a) Incorrect

b) $201

Step-by-step explanation:

$5826 need to be distributed equally among 29 employees . Hence we need to divide 5826 by 29 to know the amount each one will get. Since 58=29*2 and 26≈2, The manager can estimate that each one of the employee will get $201 as bonus. So his reason to estimate was correct but the estimated amount was incorrect.

Each employee will get

$\frac{5826}{29}$

= 200.89

Hence Each one will get

$201 rounded to nearest whole number

And for Ken, keep subtracting 20 from 600.

Once you are done, you will notice that both Barbie and Ken have $300 at 15 weeks. So your answer is 15.
