On a particularly boring transatlantic flight, one of the authors amused himself by counting the heads of the people in the seat
xxTIMURxx [149]

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 6-1=5

Hence, the answer is 5.

always Pythagoras with the coordinate differences as sides and the distance the Hypotenuse.

c² = (2/3 - 5/3)² + (-10/9 - -7/9)² = (-3/3)² + (-10/9 + 7/9)² =

= (-1)² + (-3/9)² = 1 + (-1/3)² = 1 + 1/9 = 10/9

WILL GIBE BRAINLEST
professor190 [17]

Answer:

Step-by-step explanation:

The answer choices don’t make sense. The volume of a cylinder of height 45mm and radius 5mm = π5²*45 = 1125π mm³.

Three of the answer choices are larger than 1125π.

:::::

volume of one cone = πr²h* ⅓

Volume of cylinder section = πr²h

Total volume = πr²h*⅔ + πr²h = πr²h*5/3 = π5²*15*5/3 = 625π
