scZoUnD [109]3 years ago
5 0

Step-by-step explanation:

The sum of the interior angles of a convex regular polygon is 180 times (n-2), where n is the number of sides. Since we already know the sum, we can write 3,960 = 180(n-2). If you solve for n in this equation, you will have the number of sides.

A town's population has been growing linearly. In 2003 the population was 47,000. The population has been growing by 1200 people
blsea [12.9K]

Answer:

Step-by-step explanation:

The population in 2003= 47000

Since the population increase by 1200 every year,

in 2004 the population will be 47000+1200

in 2005 the population will be 47000+(1200+1200) which is the same as

47000+2(1200) where 2 is 2 years after 2003,

Therefore the population x years after 2003 is 47000+x(1200).

P= 47000+1200x

b) The population at 2009 which is 6 years after 2003 will be

47000+(1200)*6=47000+7200= 54200

The population at 2009 is 54200,

serious [3.7K]

Answer:  $277.91

<u>Step-by-step explanation:</u>

The average of the 2 highest salaried quarters is:

\dfrac{\$13,500+\$12,775}{2}=\dfrac{\$26,275}{2}=\$3,137.50

Divide that by 26 (weeks) to find out her average weekly salary:

\dfrac{\$3,137.50}{26}=\$505.29

Multiply that by 55% (0.55) to calculate her weekly unemployment benefit:

\$505.29(0.55)=\$277.908

Round to the nearest penny --> $277.91
