Five rectangles are arranged from the least to the greatest area and named A, B, C, D, and E in order of increasing area. All di

mensions are whole numbers, and no 2 rectangles have the same area. Determine the dimensions of all 5 rectangles using the following clues:
The median area is 15 square units.

Rectangles B and D are squares.

Rectangles C and D have the same perimeter.

Rectangles A, B, and C have the same length.

Rectangles D and E have the same length.

Rectangles C and E have the same width.

Given that median area is 15 square units.

Hence rectangle C in the middle has 15 square units.

Its dimensions can be width= 5 and length = 3

SInce B is smaller than C and has the same length, B has lengh of 3 with area = 9 sq units.

D has the same perimeter = 16 units.  Since D is a square, side of D = 4 units.

Now D and E have the same length.  Hence length of E = 4 units.

Width of E = width of C = 5 units.Thus makes the area of E as 20 sq units.

Rectangle A has length =3 and width can be less than 3 since area is smaller than B.

so A has length= 3 width = 2 with area = 6 sq units.

Suppose the radius of a circle is 8. What is its area?
monitta
The Formula to find the Area of a circle using the radius is:
A =  \pi r^2

r = 8
So:
A =  \pi r^2
A =  \pi 8^2
A = \pi64

And you get about 201.06193

So, the area of a circle with a radius of 8 is about 201.06

Hope this Helps :)

EASY POINTS Find the domain of the graphed function.
Vladimir [108]

Using it's concept, it is found that the domain of the graphed function is given as follows:

D. -4 \leq x \leq 2

<h3>What is the domain of a function?</h3>

It is the set that contains all possible input values for the function. In a graph, it is given by the values of x.

In this graph, x assumes values between -4 and 2, inclusive due to the closed circle, hence the domain is given by:

D. -4 \leq x \leq 2

The ABC Company has a net income of $56,000, assets at the beginning of the year are $263,000 and assets at the end of the year
aleksandr82 [10.1K]

Answer:

19.4 %

Step-by-step explanation:

The formula for<em> return on assets</em> (ROA) is

ROA = Net income /Total assets × 100 %

Since assets vary, we use the <em>average</em> of the total assets over the period.

<em>Calculate the average total assets</em>

At beginning of year, total assets = $263 000

At end of year, total assets            = $313 000

Average = (313 000 + 263 000)/2

Average = 576 000/2

Average = $288 000

===============

<em>Calculate the ROA</em>

Net income = $56 000

ROA = 56 000/288 000 × 100 %

ROA = 0.194 × 100 %

ROA = 19.4 %

The company’s return on assets is 19.4 %.
