Suppose the length of segment BE is 11 cm. Which is the BEST ESTIMATE for segment GH?
JulijaS [17]

Answer: C) 5.5 cm.

Step-by-step explanation:

From the given , it can be clearly seen that in triangle DBE , G and H are the midpoints of segment DB and DE respectively.

Also, GH is parallel to BE. [By Converse of Basic proportionality theorem]

Length of BE= 11 cm.

Further more,

\dfrac{DB}{DG}=\dfrac{BE}{GH}\\\\\Rightarrow\dfrac{2DG}{DG}=\dfrac{11}{GH}\ \ [{DG=GB,\therefore\ DB=2DG }]

\Rightarrow\ \dfrac{2}{1}=\dfrac{11}{GH}\Rightarrow\ GH=\dfrac{11}{2}=5.5\text{ cm}

Hence, the  BEST ESTIMATE for segment GH is 5.5 cm.

Note :

Converse of Basic Proportionality Theorem says that when a line (or a segment) divides any two sides of a triangle in equal proportion then the line ought to be parallel to the remaining third side.

Pls pls pls help answer quick
lord [1]

Answer:

120 m

Step-by-step explanation:

To find the volume of the prism on the bottom, multiply length times height times width

3x3x12=108

next is the pyramid on top.

Formula is V=bh x 1/2

8, the height, times 3, the base, = 24

24x 1/2 or 24/2 = 12

108+12= 120

120 m
