Answer: The area of the figure is 400 square inches

Step-by-step explanation: Please refer to the diagram attached.

The diagram in the question shows a parallelogram ABCD attached to a right angled triangle EBC.

In order to compute the total area of the entire figure, the area of both detachments would have to be calculated separately and then summed up.

To calculate the area of a parallelogram ABCD, the formula is

Area = b x h

where b = base and h = perpendicular height.

The base is 20 inches while the height is 16 inches.

Therefore,

Area = 20 x 16

Area = 320 in^2

Next we calculate the area of triangle EBC. Area of a triangle is given as

Area = 1/2 base x height

Where the base = 20 (line AD is equal to line BC = 20) and height = 8. Therefore,

Area = 1/2 (20) x 8

Area = 10 x 8

Area = 80 in^2

Having calculated the area of the two parts of the entire figure, the area of the entire figure is given as

Area of parallelogram ABCD + Area of triangle EBC

We now have 320 + 80 = 400

Hence, area of the figure = 400 square inches

Check the picture below.

so the area of that figure is simply the area of that triangle and parallelogram added up.

\bf \stackrel{\textit{triangle's area}}{\cfrac{1}{2}(20)(8)}~~ + ~~\stackrel{\textit{parallelogram's area}}{(20)(16)}\implies 80+320\implies 400

Find the solution to the system of equations.
harina [27]

Answer:

x=2

y=3

Step-by-step explanation:

y=−2x+7

y=5x−7

Set the two equations equal since they are both equal to y

−2x+7 =5x−7

Add 2x to each side

-2x+7+2x = 5x-7+2x

7 = 7x-7

Add 7 to each side

7+7 = 7x-7+7

14 =7x

Divide by 7

14/7 = 7x/7

2 =x

Now find 7

y = 5x-7

y = 5(2) -7

y = 10-7

y = 3

The following function represents the value of a motorcycle, in dollars, after x years: f(x) = 19,000(0.91)x
Semenov [28]

Answer:

Option C.The decrease in the value of the motorcycle, which is 9%

Step-by-step explanation:

we have a exponential function of the form

f(x)= ab^x

where

a is the initial value

b represents growth or decay factor

If b >1 then it is an exponential growth

if 0<b<1 then it is an exponential decay

In this problem

a=$19,000

b=0.91 -----> it is exponential decay factor

Find the rate of decrease r

b=(1-r)

substitute

0.91=1-r

r=1-0.91=0.09

Convert to percentage

0.09*100=9%

therefore

0.91 represent the decrease in the value of the motorcycle, which is 9%

Evaluate u + xy, for u = 20, x = 5, and y = 7.
Yanka [14]

Answer:

55

Step-by-step explanation:

u + xy, for u = 20, x = 5, and y = 7

u + xy = 20 + 5 * 7 = 20 + 35 = 55
