A theater has 22 rows of seats. The first row has 18 seats, the second row has 20 seats, the third row has 22 seats, and so o

Answer:

1078

Step-by-step explanation:

Total no of rows (n) = 22

Since, 18, 20, 22 ..... forms an arithmetic sequence with first term (a) = 18 and common difference (d) = 2.

We need to find: Total no of seats in the theatre $(S_{22}).$

Formula to be used:

$S_{n}= \frac{n}{2}\bigg[2a+(n-1)d\bigg]$

Plug the values of a, d and n in the above formula, we find:

$\implies S_{22}= \frac{22}{2}\bigg[2(28)+(22-1)(2)\bigg]$

$\implies S_{22}=11[56+(21)(2)]$

$\implies S_{22}=11[56+42]$

$\implies S_{22}=11[98]$

$\implies S_{22}=1078$

Thus, there are total 1078 seats in the theatre.

Use the given information to find the lengths of the other two sides of the right triangle if side a is opposite angle A, side b

weeeeeb [17]

c = $\frac{4\sqrt{30} }{9}$

using Pythagoras' identity on the right triangle

c = √( 4² + ( $\frac{28}{9}$ )² ) = √16 + $\frac{2080}{81}$

= $\frac{\sqrt{2080} }{9}$ = $\frac{4\sqrt{130} }{9}$

$48 decreased by 25%

Mice21 [21]

25% is the same as .25 when solving math problems.

So 25% of $48 can be found by $48*.25, which equals $12.

So if $48 is decreased by $12, then we are left with $48-$12=$36
