I hope this help 4 squared equals to 12 and 3 time 12 equal 36 then 36 plus 1 equal 37 so 37 is the output

Look at the angles for all regular polygons. As the number of sides increases, do the measures of the angles increase or decreas

Verdich [7]

Answer:

As the number of sides increases, the measures of the angles increase

see the explanation

Step-by-step explanation:

we know that

The measure of the interior angle in a regular polygon is equal to

$x=\frac{(n-2)}{n}(180^o)$

where

n is the number of sides of the regular polygon

x is the measure of the interior angle in a regular polygon

we have that

Examples

A triangle

n=3 sides

$x=\frac{(3-2)}{3}(180^o)=60^o$

A square

n=4 sides

$x=\frac{(4-2)}{4}(180^o)=90^o$

A pentagon

n=5 sides

$x=\frac{(5-2)}{5}(180^o)=108^o$

A hexagon

n=6 sides

$x=\frac{(6-2)}{6}(180^o)=120^o$

n ----> 3,4,5,6...

x ----> 60°,90°,108°,120°,...

As the number of sides increases, the measures of the angles increase

The pattern is $x=\frac{(n-2)}{n}(180^o)$

A study showed that there are 16 vehicles for every 10 households. How many vehicles are there for 107 million households?

Komok [63]

$16v........10h \\x......107.000.000h \\\\ x=\frac{16*107.000.000}{10} \\\\ x=16*10.700.000 \\\\ \boxed{x=171.200.000 \ vehicles}$

Charlie and his friend Jay went to the fair. They were having a sale and the admission was 25% off. The regular ticket price was

lidiya [134]

Answer:

The total of Charlie's be $7.

Step-by-step explanation:

Given:

Charlie and his friend Jay went to the fair. They were having a sale and the admission was 25% off.

The regular ticket price was $9.00.

And the tax is 6%.

Now, to find Charlie’s total.

So ,we deduct the 25% off first:

$\$9.00-25\%\ of\ \$9.00$

$=9-\frac{25}{100} \times 9$

$=9-\frac{225}{100}$

$=9-2.25$

$=\$6.75.$

Now, including tax :

$\$6.75+6\%\ of\ \$6.75$

$=6.75+\frac{6}{100} \times 6.75$

$=6.75+0.06\times 6.75$

$=6.75+0.405$

$=\$7.155.$

Approximately = $7.

Therefore, the total of Charlie's be $7.
