9.) In a state with a sales tax of 7%, Hernando
alex41 [277]

Answer:

Final price = $79.16

Step-by-step explanation:

Given that:

Sales tax in the state  = 7%

Amount spent by Hernando = $73.98

Amount of sales tax = 7% of 73.98

Amount of sales tax = \frac{7}{100}*73.98

Amount of sales tax = 0.07 * 73.98

Amount of sales tax = $5.18

Final price = 73.98 + 5.18 = $79.16

Hence,

Final price = $79.16

A rectangular field is to be enclosed by a fence and divided
Phantasy [73]

Answer:

80000 square meters

Step-by-step explanation:

perimeter + dividing fence = 800

let a = length

let b = width

let c = length of dividing fence

perimeter = 2*a + 2*b

let's say...

c is the same as the length

2a + 2b + c = 800

2a + 2b + a = 800

3a + 2b = 800

area = length*width

area = a*b

area / b = a

3*(area/b) + 2b = 800

3*(area/b) = 800 - 2b

area/b = (800 - 2b)

area = (800 - 2b)*b

To make the area large, we make the right hand side large.

800b - 2b^2

If you put in terms of x, y it looks like a downward opening parabola, so the max area is at the vertex. Half way between the roots.

y = -2x^2 + 800x

y = -x^2 + 400x

0 = x*(-x + 400)

roots are x= 0 and x = 400

vertex is at x, aka b = 200

area at b=200 is (800 - 400)*200 = 80000

and a is area/b... 80000/400 = 200
