Given:

26 meter-long wire cut into two pieces

let x = perimeter of square
     26 -x = perimeter of circle

Use the formulas for the perimeters and areas of the two shapes:

P sq = x = 4s
P ci = 26 - x = 2 * pi * r

A sq = s^2
A ci = pi * r^2

Manipulate the equations to come up with a maximum and minimum function. Equate the function to zero and solve for x, then find the area.

Two brothers, Mark and Charles, each inherit $31000. Mark invests his inheritance in a savings account with an annual return of
Nutka1998 [239]

Answer:

$1,085

Step-by-step explanation:

Data provided in the question:

Amount inherited and invested i.e principle = $31,000

Annual return for Mark on savings account = 2.9% = 0.029

Annual return for Charles on CD = 6.4% = 0.064

Now,

The Interest earned by Mark in 1 year = principle × Rate × Time

= $31,000 × 0.029 × 1

= $899

The Interest earned by Charles in 1 year = principle × Rate × Time

= $31,000 × 0.064 × 1

= $1,984

Therefore,

More Money that Charles have than Mark = $1,984 - $899

= $1,085

stich3 [128]
For an instance, n represents the number
\frac{25}{4}+n=4n- \frac{3}{4}
n-4n=-\frac{3}{4}-\frac{25}{4}
-3n=-\frac{28}{4}
n=-\frac{28}{4} \times -\frac{1}{3}
n= \frac{28}{12}
n= \frac{7}{3}

The number is 7/3
