Answer:

i) 32100 people

ii) 674100

iii) 5%

Step-by-step explanation:

The population in 2009 was : 642,000

The percent increase was by : 5%

This means the population in 2010 will be :

105/100 * 642000 = 674,100

i) Increase in population is ;  674,100 - 642,000 = 32100 people

ii) The population in 2010 was : 674,100

iii) Population of 2009 = 642000

   Population of 2010 = 674,100

   Increase in population = 674,100 - 642000 = 32100

   Percent increase = increase/ original population * 100

   Percent of increase = 32100/642000 * 100 = 5%

Ede4ka [16]

Answer:

Step-by-step explanation:

During the breaststroke competitions of a recent olympics, Nelson diebel swam 100 meters in 62 seconds, this means that his unit rate would be 100/62 = 1.61 meters per second.

Mike bower man swam 200 meters in 130 seconds. This means that his unit rate would be 200/130 = 1.54 meters per second. The rate of 1.61 meters per second is higher than the rate of 1.54 meters per second. Therefore, Nelson diebel swam at a faster rate.

Please help, need to find x and y :))
blondinia [14]

Answer:

x=14

y=140

Step-by-step explanation:

Using (9x+14) + (3x-2) = 180, we can solve this equation.

First add like values giving you 12x+12=180. Then subtract 12 from both sides giving you 12x=168.

Then divide both sides by 12 giving you x=14.

Finally, just simply set 9x+14 equal to y and substitute x for 14. This gives you 140=y

Hope this helped

What is the value of x?
GenaCL600 [577]

Answer:

<h2>x = 3</h2>

Step-by-step explanation:

Look at the picture.

We have the triangles 45° - 45° - 90° and 30° - 60° - 90°.

The sides of those triangles are in ratio:

1 : 1 : √2 and 1 : √3 : 2

Therefore

If AC = 6√2 then AB = BC = 6

If BC = 6 then x = 6 : 2 = 3
