Answer:
6.83 units
Step-by-step explanation:
Let the height of the original pyramid be represented by h. Then the cut off top has a height of (h -2). The scale factor for the area is the square of the scale factor for height, so we have ...
(height ratio)^2 = 1/2
((h -2)/h)^2 = 1/2
(h -2)√2 = h . . . . . . square root; multiply by h√2
h(√2 -1) = 2√2 . . . . add 2√2 -h
h = (2√2)/(√2 -1) ≈ 6.8284 . . . units
The altitude of the original pyramid is about 6.83 units.
I believe it is 4 to make it able to divide by both sides
Answer:
3/4 of cookie per each friend.
Step-by-step explanation:
Since you have 4 friends, and only have 3 cookies,
the fraction is 3/4. why? because 3/4= 0.75
which makes 0.75x 4 friends= 3 cookies . Each friend will get 0.75 or 75% of cookie which is the same as 3/4.
