Answer:
35 cm
Step-by-step explanation:
Perimeter is the sum of all edges of the given figure.
Given: the perimeter of the base of the regular triangular pyramid is P = 16.5 cm and the perimeter of a lateral face is 18.5 cm.
To find: sum of all edges of this pyramid
Solution:
sum of all edges of this pyramid = perimeter of the base of the regular triangular pyramid + perimeter of a lateral face = 16.5 + 18.5 =35 cm
Answer:
9/20
Step-by-step explanation:
Well, in order to first determine the slope or y-intercept, you must put change the equation to this format: y=mx+b.
m=slope and b=y-interceptI
in order to do that, you must change this equation.
x+3y=9
-x -x
----------
3y=9-x
Then, rewrite it as:
3y=-x+9
_______
3 3
simplify to
y=-x/3 +9
