Divide the figure using vertical lines into 3 sub-areas.  You have already done this on the left side of the figure.  The base of this trapezoid is (30-10 -12) ft, or 8 ft.  The trapezoid has 2 heights shown:  one is 11 ft and the other is 15 ft.
The area of this trap. is  [ (11 ft + 15 ft)/2 ] * [8 ft]  ], or 13*8 ft^2, or 104 ft^2.

Next is the rectangle in the middle.  Its height is 15 ft and its width is 12 ft.  Its area is (15 ft)(12 ft) = 180 ft^2.

Last is the trapezoid on the right.  Its base is 10 ft and the average of its heights is [(15+7.5) ft] / 2, or  11.25 ft.  Thus, the area of this trap. is
(11.25 ft)(10 ft) = 112.5 ft^2.  

Add these 3 sub-areas together to get the total area.

Good luck!!

The relationship between lines KO and K’O’ is given as Line K'O' = 5 * line KO

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

Transformation is the movement of a point from its initial point to a new location. Types of transformation are<em> reflection, rotation, translation and dilation.</em>

Dilation is the increase or decrease in size of a figure by a scale factor.

The larger figure was dilated using a scale factor of 5, hence:

Line K'O' = 5 * line KO

The relationship between lines KO and K’O’ is given as Line K'O' = 5 * line KO

A bank pays 5% interest compounded annually. What principal will grow to $12,000 in 10 years.
makvit [3.9K]
<h3>Answer: 7366.96 dollars</h3>

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

Use the compound interest formula:

A = P(1+r/n)^(n*t)

where in this case,

A = 12000 = amount after t years

P = unknown = deposited amount we want to solve for

r = 0.05 = the decimal form of 5% interest

n = 1 = refers to the compounding frequency (annual)

t = 10 = number of years

-------

Plug all these values into the equation, then solve for P

A = P(1+r/n)^(n*t)

12000 = P(1+0.05/1)^(1*10)

12000 = P(1.05)^(10)

12000 = P(1.62889462677744)

12000 = 1.62889462677744P

1.62889462677744P = 12000

P = 12000/1.62889462677744

P = 7366.95904248911

P = 7366.96
