 WILL GIVE BRAINLIEST ANSWER PLEASE HELP In a theater there are 12 seats on the first row and 16 seats in the second row. the nu
faltersainse [42]

(a) a_{n} = 4n + 8

(b) row 13 has 60 seats

(a)

the sequence of seats is an arithmetic sequence whose n th term is

a_{n} = a_{1} + (n - 1 )d

where a_{1} is the first term and d the common difference

here the sequence is 12, 16, ....

with a_{1} = 12 and d = 16 - 12 = 4, thus

a_{n} = 12 + 4( n - 1 ) = 12 + 4n - 4 = 4n + 8

(b)

calculate the number of rows n when 60 seats

solve 4n + 8 = 60 ( subtract 8 from both sides )

4n = 52 ( divide both sides by 4 )

n = 13 ← number of rows

How to find the area r = 6 ft
Darya [45]

I am assuming this is for a circle??

 Area for  circle is pi*r^2

you didn't say what to use for pi so I will use 3.14

so area = 3.14 * 6^2

6^2 = 36 

so 3.14*36 = 113.04 square feet. Round this answer off as needed.

Tems11 [23]

Answer:

Step-by-step explanation:Let - be a fraction in simplest form, b # 0, written

as a repeating decimal when in decimal form.

Since the only numbers which can be factors of the

denominators lead to a terminating decimal are 1, 2

and 5 (including rising to powers) and combinations

of them, it means that if the denominator has at

least one of the other numbers at the denominator,

the decimal form will be a repeating decimal.

Among the numbers from 1 to 10, the presence of

any of these numbers in the denominator will lead

to a repeating decimal:
