Answer:

50cm or 500 mm

Step-by-step explanation:

A quadrilateral is a four sided figure. So, the base of the quadrilateral pyramid has four sides. It also has 4 edges and 4 bases

sum of edges = sum of base edges + sum of lateral edges

1cm = 10mm

55mm = 5.5cm

sum of base edges : 5.5 x 4 = 22cm

sum of lateral edges : 7 x 4 = 28 cm

22 + 28 = 50 cm or 500mm

Line m has a slope of 8/5. line n is perpendicular to line m. what is the slope of line n?

yulyashka [42]

$m_{1}m_{2} = - 1$

$\frac{8}{5} \times m_{2} = - 1$

$m_{2} = \frac{5}{8} \times - 1$

$\boxed{ m_{2} = \frac{ - 5}{8} }$

True or false, rotational symmetry is the quality a design has if it maintains all characteristics when it is rotated about a po

Andru [333]

In fact, if a design still looks the same after some rotation, then it has Rotational Symmetry. In this context, this design can be an object, a figure, a thing, etc. So these characteristics is the typical quality or feature of this object, figure or thing. An example of rotational symmetry is the Ferris Wheel when it rotates about the center.
