What you want to do is found a common denominator which is 20, so you would multiply 7/4 times 5 and 8/5 times 4. So it would be 35/20-32/20 and the answer is 3/20.

Answer:

<em>XY = 92 units</em>

Step-by-step explanation:

<u>Similar Shapes</u>

Two shapes are similar if all their corresponding side measures are in the same proportion.

The triangles UVW and YVX are similar because their side lengths are in the proportion 1:2, given the tick marks provided in the drawing.

This means that the measure of VX is twice the measure of VW,

The measure of YV is twice the measure of UV

The measure of XY is twice the measure of UW

This last proportion gives the equation:

z + 46 = 2z

Solving for z:

z = 46

Thus, XY = z+46 = 92

XY = 92 units

Answer:

   68.04 cm^3

Step-by-step explanation:

The volume of the prism is given by

V = Bh

where B is the area of the base and h is the height

B - area of the triangle

B = 1/2 bh = 1/2 (5.4) (3.6) = 9.72

The volume is

V = 9.72*7
