Quadrilateral ABCD in the figure below represents a scaled-down model of a walkway around a historic site. Quadrilateral EFGH re
Mkey [24]

the picture in the attached figure

Step 1

Find the perimeter of the scaled-down model of a walkway (Quadrilateral ABCD)

P=AD+DC+CB+BA\\P=3+2+2+4\\ P=11 in

Step 2

Find the scale factor

if Quadrilateral ABCD is similar to Quadrilateral EFGH

then

PerimeterEFGH=PerimeterABCD*scale factor

scale.factor=\frac{EF}{AB} \\ \\ scale.factor=\frac{60}{4} \\ \\ scale.factor=15\frac{ft}{in}

Step 3

Find the perimeter of the actual walkway (Quadrilateral EFGH)

PerimeterEFGH=PerimeterABCD*scale factor

PerimeterEFGH=11*15

PerimeterEFGH=165 ft

therefore

the answer is

165 ft

In the graph of the inequality x > 2, what does a dashed line at x = 2 indicate?
ryzh [129]

Answer:

option 4: The line x = 2 is not included in the solution region is the correct option.

Step-by-step explanation:

Given the inequality

x > 2

It is clear that the given inequality is in the simple form which indicates that x is greater than 2.

Please check the attached graph.

As x is greater than 2, thus a dashed line at x = 2 on the graph indicate indicates that x = 2 is not included in the solution region.

  • <em>Please remember that inequalities that use < or > symbols are drawn with a dashed line in order to display that line is not included in the region.</em>

Thus, the solution to the inequality is:

x>2\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x>2\:\\ \:\mathrm{Interval\:Notation:}&\:\left(2,\:\infty \:\right)\end{bmatrix}

The solution indicates that that the value of x will be greater than 2.

Please check the attached graph.

A dashed line at x = 2 on the graph indicates that x = 2 is not included in the solution region.

Hence, option 4: The line x = 2 is not included in the solution region is the correct option.

Without graphing, is each system independent, dependent, or inconsistent? { -x-3y=0 x-y=4
Kryger [21]
Since we can find a solution for this system of equations we can affirm this is an independent system with solution equal to (x,y) = (3,-1)

* If we graph a dependent system in the slope - intercept form, we can see that the graphs of each one are identical to each (beacuse we are representing the same line).

*An inconsistent system occurs when the equations have the same slope, but different values of intersection with the Y axis.
