Answer:
Smallest number of rows that is needed to seat these people = 16
Step-by-step explanation:
Given - A theatre has seats arranged in rows of 24, three hundred eighty -two(382) people attend a show at the theatre.
To find - What is the smallest number of rows that is needed to seat these people?
Solution -
Given that,
Total number of seats in a Row = 24
Let us assume that, there are x rows
As.
There are 382 people in the Theatre
So,
Minimum seats required is
24 x = 382
⇒x = 382 ÷ 24
⇒x = 15.91
i.e.
Smallest number of rows that is needed to seat these people = 16
I'll just assign a value of x and solve it so that I'll be able to arrange them in order from greatest to least.
I am assuming that x = 2.
4x + 9 ⇒ 4(2) + 9 = 8 + 9 = 179^x + 1 ⇒ 9² + 1= 81 + 1 = 82x² + 3 ⇒ 2² + 3 = 4 + 3 = 74x ⇒ 4(2) = 89^x ⇒ 9² = 81x² ⇒ 2² = 4
based on my assumption, the order from greatest value to least value is:1) 9^x + 12) 9^x3) 4x + 94) 4x5) x² + 36) x²
80 increased by 15% is 92.
80 x .15 = 12
12 + 80 = 92
Answer = 92
