Step-by-step explanation:

Red marble probably currently: 12/32 = 3/8

Guess and check (using the multiple choice answers):

F: 12 + 13 / 32 + 13 = 25/45 = 5/6; does not equal 3/5

G: 12 + 18 / 32 + 18 = 30/50 = 3/5; does equal 3/5

H: 12 + 28 / 32 + 28 = 40/60 = 2/3; does not equal 3/5

J: 12 + 32 / 32 + 32 = 44/64 = 11/16; does not equal 3/5

K: 12 + 40 / 32 + 40 = 52/72 = 13/18; does not equal 3/5

Which best describes the lateral faces of all prisms? parallelograms squares rhombi rectangles?

Murljashka [212]

Any face on a prism that is not a base is a lateral face (see the attached image). The prism in the picture has a hexagonal base (6 sided) and 6 lateral faces. The lateral faces meet each other at lateral edges, as well as meeting both bases. Each lateral face is a polygon with four sides. All edges of the laterals are the same size and parallel. This makes the lateral faces parallelograms, containing a 4-sided figure with opposite sides that are parallel.
