Pyramid A has a quadrilateral base, a height of 4 units, and a volume of 20 cubic units. Pyramid B has the same base area, but its height is 12 units. What is the volume of pyramid B? Choose 1 Choose 1 (Choice A) A 20 cubic units (Choice B) B 60 cubic units (Choice C) C 180 cubic units (Choice D) D 540 cubic units

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.

median- 36f

mode - none

mean- 33.7 ~ 34f

step-by-step explanation:

assume that y=mx+n

you may see as , where

in we change places of numerator and denominator, then we insert an opposite sign

and substitute m=-1/3 in the equation y=mx+n

point (4,2), so we substitute x=4, y=2 to the equation and calculate

the answer is
