  C.  18 inches

Step-by-step explanation:

The median of a trapezoid is the line segment that joins the midpoints of the sides of the trapezoid. It is halfway between the parallel bases, and is parallel to them. It length is the average of the lengths of the two bases:

stealth61 [152]

Answer:

Volume = 176ft^3

Step-by-step explanation:

Given

Height = 8

See attachment for base dimension

Required

Determine the volume of the storage unit

From the attachment, we can split the base dimension into two rectangles.

CDEF and ABCG

And the dimensions are:

<u>CDEF</u>

EF = CD = BD - BC = 5 - 2 = 3

ED = FC = FG +AB = 4 + 2 =6

So, the area of CDEF is:

Area = EF * ED

Area = 3 * 6

Area = 18

<u>ABCG</u>

<u></u>AB= GC = 2<u></u>

<u></u>AG = BC = 2<u></u>

<u></u>

<u></u>Area = AB * AG<u></u>

Area = 2 * 2

Area = 4

So, the base area is:

Base\ Area = 18 + 4

Base\ Area = 22

The volume is then calculated as:

Volume = Base\ Area * Height

Volume = 22 * 8

Volume = 176

What is the equation of the graph
vredina [299]

9514 1404 393

Answer:

  the correct choice is marked

Step-by-step explanation:

The line has a rise of 2 for a run of 1, so a slope of 2. The line crosses the y-axis at y=-2, so the y-intercept is -2. The slope-intercept equation for the line is ...

  y = mx + b . . . . . . for slope m and y-intercept b

  y = 2x -2
