Alexander Graham Bell, the inventor of the telephone, also invented a kite made out of "cells' shaped like triangular pyramids. A kite is made out of triangular pyramids with fabric covering one face and the base of the pyramid. The face and base both have heights of 17.3 cm and side lengths of 20 cm. How much fabric is needed to make each pyramid cell for the kite?

The fabric needed for each pyramid cell of the kite will have an area of 173 cm².

Step-by-step explanation:

Area of a face of the triangular pyramids = (1/2)(b)(h)

where

b = base of a triangle of the triangular pyramid = 20 cm

h = height of each triangle of the triangular pyramids = 17.3 cm

Area = (1/2)(20)(17.3) = 173 cm²

Just like the image presented with the question, each face of the pyramid that has a cell of fabric has only one, So, the fabric needed for each pyramid cell of the kite will have an area of 173 cm².

Hope this Helps!!!

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

i think the answer is c sorry if it's wrong
