A concert hall has 12 seats in the first row, 14 seats in the second row, 16 seats in the third row, and so on. If the pattern c
Marrrta [24]

Given:

The number of seats in the first row is <em>a</em>₁ = 12.

The series of the increasing number of seats is 12, 14, 16......

The objective is to find the total number of seats in the first 12 rows.

Explanation:

The difference between the number of seats in each row can be calculated by the difference between the successive terms of the series.

\begin{gathered} d=14-12=2 \\ d=16-14=2 \end{gathered}

The number of rows to be calculated is <em>n</em> = 12.

To find the number of seats:

The number of seats presents in the first 12 rows can be calculated as,

S_n=\frac{n}{2}\lbrack2a_1+(n-1)d\rbrack

On plugging the obtained values in the above equation,

\begin{gathered} S_{12}=\frac{12}{2}\lbrack2(12)+(12-1)2\rbrack \\ =6\lbrack24+11(2)\rbrack \\ =6(46) \\ =276 \end{gathered}

Hence, the total number of seats in the first 12 rows is 276.

Explain how you can tell 5/12 is less than 1/2 without using a model?
castortr0y [4]
5/12 is less than 1/2 because 6/12 = 1/2
Therefore, there are not enough 1/12 pieces to equal or exceed 1/2.

Find the circumference and the area of a circle with diameter 2 cm . Use the value 3.14 for π , and do not round your answers. B
Fynjy0 [20]
Circumference= 2×pi×R
Area= pi× R^2
Since Diameter=2 cm ---> Radius is 2× diameter , so R=4 cm

Circumference=2×3.14×4= 25.12 cm
area=3.14× (4)^2= 50.24 cm^2
