The circular area surrounding the design is an existing rock bed are 24.5, 21, 27, 91 and 91 ft sq.

<h3>What is a parallelogram?</h3>

That quadrilateral in which opposite sides are parallel is called a parallelogram.

Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.

It is given the bases of the trapezoids are 6 ft and 8 ft,

The heights of the trapezoid and the parallelogram are 3.5 ft each, and the horizontal distances between the left and right vertices of each rhombus is 2 ft.

Trapezoid

Area = 1/2(3.5)(6 + 8)

Area = 24.5

Parallelogram

Area = 1/2(3.5)(6)

Area = 21

Rhombus

Area = 1/2(7)(2)

Area = 7

Red Area

Area = 2(21) + 2(2.4)

Area = 91

White Area

Area = 2(21) + 2(2.4)

Area = 91

The area of a regular hexagon is 55 in^2. Find the length of a side. Round your answer to the nearest tenth. I know the answer i
True [87]
Polygon area = n*side length^2 / [4*tan(180/n)]
side length^2 = polygon area * [4*tan(180/n)] / n
where n is the number of sides
side length^2 = 55 sq inches * (4*tan(180/6)) / 6
side length^2 = 55 sq inches * 4 * tan (30) / 6
side length^2 = (55 sq inches * 4 * 0.57735) / 6
side length^2 = <span> <span> <span> 127.017 </span> </span> </span> / 6
side length^2 = <span> <span> <span> 21.1695 </span> </span> </span>
side length = square root ( <span> <span> <span> 21.1695 </span> </span> </span> )
side length = <span> <span> <span> 4.6010324928 </span> </span> </span>

Need help.....thanks so much

Start by adding up the total sales in 2011 and 2012. You can make approximate estimates for the bars that are between lines. Since everything is in millions, you can ignore the 6 zeros behind every number to speed up your calculation:

1) In 2011, Asia sold 250, America sold 325, Europe sold ~210, Africa sold 150. The total in 2011 was 250+325+210+150 = 935.

2) In 2012, Asia sold ~130, America sold ~280, Europe sold ~230, and Africa sold ~140. The total in 2012 was 130+280+230+140=780.


Now find the percent decrease. Percentage decrease is basically what percent of your original number was subtracted from that original number to get the new number. 
Percent decrease is calculated by (1) calculating the decrease from original number-new number, then (2) dividing that decrease by the original number, and then (3) multiplying your quotient by 100% to get a percentage:

1) Your original number is 935, from 2011, because that's the year you started out with. Your final number is 780, from 2012. The decrease is: 935-780 = 155. 

2) Divide 155 by your original number. 155/935 ≈ 0.17

3) Finally multiply your quotient from step 2 by 100% to get your percent decrease: 0.17*100% = 17%.

The answer is A) 17.
