There are 440 thousands :)
There are 6 surfaces on a rectangular prism . 3 pairs of equal area.
Surface area 2wl + 2hw + 2 hl where h = height, w = width, l = length.
So inserting the given values:-
442 = 2*w*11 + 2 *8* w + 2*8*11
442 = 22w + 16w + 176
38w = 442-176 = 266
w = 7
width = 7 feet
25%. With a 50% chance of it landing heads the first time, you need to multiply it by the percentage that you have that it will land on heads again, which is 50. 50% of 50 is 25, and then having it land on either heads or tails for the third time is guaranteed, so multiply that probability (100%) by the previous 25% which ends up being simply 25%
Step-by-step explanation:
When you complete the square, you change the equation so that the left side of the equation is a perfect square trinomial. But mainly completing the square is a technique that transforms your quadratic equation from an equation that can't be factored into one that can.
