Answer:

100,100

Step-by-step explanation:

perimeter=400 m

length=x

let width=y

2(x+y)=400

x+y=200

y=200-x

area A=xy=x(200-x)=200x-x²

\frac{dA}{dx} =200-2x\\when \frac{dA}{dx} =0\\200-2x=0\\x=100\\\frac{d^2A}{dx^2} =-2

In 2001, a company marketed 730,000 units of its product. In 2001 its yearly volume was 50% of its volume for 2004. The 2004 vol
Dmitriy789 [7]

Answer:

4000 units

Step-by-step explanation:

In 2001 the total number of marketed units= 730,000

If this number represents 50% of what was marketed in 2004, then the total number of units marketed in 2004 was:

(100/50)× 730,000=1460000

To get the number for each of the 365 days in 2004 we divide the total for 2004 by 365

1460000/365= 4000 units

Find the area of the figure below by first finding the areas of the rectangle and triangles.
masha68 [24]

a. The area of the rectangle: 16 units²

b. The area of the triangle on the left: 6 units²

c. Area of the triangle on the right: 10 units²

d. Area of the figure: 32 units²

<h3>What is the Area of a Rectangle and a Triangle?</h3>
  • Area of a rectangle = (l)(w)
  • Area of a triangle = 1/2bh

a. l = 4 units

w = 4 units

Area of the rectangle = (4)(4) = 16 units²

b. b = 3 units

h = 4 units

Area of the triangle on the left = 1/2(3)(4) = 6 units²

c. b = 5 units

h = 4 units

Area of the triangle on the right = 1/2(5)(4) = 10 units²

d. Area of the figure = 16 + 6 + 10 = 32 units²
