The population of a town in 2000 was 430. The population is increasing at a rate of 0.9% every year. What will be the projected

mel-nik [20]

Answer:

1018.

Step-by-step explanation:

The multiplying factor here is 1 +0.09 = 1.09. Every year the current population figure is multiplied by 1.09. We have 10 years of growth so:

P(2010) = 430(1.09)^10

= 1018.

Any suggestions or answers

Sati [7]

Answer:

$x=81\degree$

$y=99\degree$

$z=129\degree$

Step-by-step explanation:

The sum of the interior angles of a triangle is 180 degrees.

$\implies 51\degree+48\degree+x=180\degree$

$\implies 99\degree+x=180\degree$

$\implies x=180\degree-99\degree$

$\implies x=81\degree$

Use the exterior angles theorem to find y.

The exterior angle y is the sum of the two remote interior angles:

$y=51\degree+48\degree=99\degree$

The sum of angles on a straight line is 180 degrees.

$\implies z+51\degree=180\degree$

$\implies z=180\degree-51\degree$

$\implies z=129\degree$
