Answer:
The answer is 5.
Step-by-step explanation:
Total number of people noticed by author = 28
Total number of black haired people = 27
So, total number of non black haired people = 1
Also given that 6 people had whole row of seats to themselves.
Let x be the number of non black haired people who had a whole row to themselves.
Since there is only one person with non black hair and has a whole row to himself because it is mentioned that one person had a row to himself which is non black haired.
Looking at above information we can say that x = 1.
Now we can say that the number of black haired people who had a whole row to themselves = 6-x
or
Hence, the answer is 5.
We have been given that side length of pyramid the square base is 12 cm and its slant height is 10 cm. We are asked to find the height of the pyramid.
We will use slant height of a pyramid formula to solve our given problem.
,where,
s = Slant height,
h = Height,
a = Each side of square base.
Upon substituting our given values in above formula, we will get:
Switch sides:
Let us square both sides:
Now we will take positive square root of both sides.
Therefore, the height of the pyramid is 8 cm and option 'b' is the correct choice.
