The volume of a cone with height h and radius r can be found using the formula V = ²h

Tom [10]

Answer:

b=2

Step-by-step explanation:

We fist of all open the brackets.

6(2b-4) =0

= 12b-24=0

Then we combine like terms

( whenever a sign crosses over an equal to sign it changes)

12b = 0+24

12b=24

Divide by co-efficient of b which is 12

12b = 24

12 12

b=2

seven people arrive to dinner, but the circular table only seats six. if two seatings such that one is a rotation of the other a

Alenkinab [10]

6 different people chosen from 7 can sit around the circular table in 840 ways.

Given that there are 7 people who have arrived for dinner.

But the circular table only seats 6.

Hence 1 person can be left out.

This can be done in 7 ways, which is a simple case of permutation.

A permutation is a combination of objects arranged in a particular sequence. The elements of sets are arranged in this case in a linear or sequential sequence.

Now 6 people will have to sit on the circular table.

Now from the properties of combination we know that , if n people sit around a circular table, then they can sit in n! ways.

Therefore 6 people can sit around a circular table in 6! ways.

6! = 120

Therefore total number of ways = 120 × 7 = 840

Hence 6 different people chosen from 7 can sit around the circular table in 840 ways.
