If the population of a town grew 21% up to 15,049. What is the population last year?

1 answer:

5 0

You can try formulating an equation to model this change:

Let 'x' be the population of the town last year. It follows that:
$1.21x = 15049 
$
and hence
$x = \frac{15049}{1.21}$

Answer:

$= \frac{\sin(2 \alpha ) + \cos(2 \alpha ) - \cos(6 \alpha ) }{ \sin(4 \alpha ) + 2 { \sin }^{2} \alpha - 1} \\ = \frac{ \sin( - 270) + \cos( - 270) - \cos( - 810) }{ \sin( - 540) + 2 { \sin }^{2}( - 135) - 1 } \\ = \frac{1}{ - 2} \\ = - 0.5$

lianna [129]

322kmh x1000= 322,000 meters per hour
That is the relationship between km and m
Because we are turning bigger units into smaller we the number will increase.

example 2 wks = 14 days two became 14 - it increased
