Alex is 1.6 m tall and Noah is 1.5 times as tall as Alex. How much tall is Noah in centimeters?

1 answer:

3 0

D= difference in height

A= Alex's height (1.6m) N= Noah's height (1.5A)

Step 1:

D=N-A

substitute N= 1.5 A in for N

D= 1.5(1.6) - 1.6

D= 2.4 - 1.6

D= 0.8 m difference in height

Step 2:

Convert meters to centimeters 1 m = 100 centimeters

0.8 x 100-80cm

Noah is 80cm taller than Alex.

Hope this helps! :)

If the population was 40,000 at the beginning of 2009, at the end of 2009 it has increased by 10% and became 44,000.

By the same way, at the end of 2010, it became $44000 + \frac{44000*10}{100} = 48400$

At the end of 2011, the population was $48400 + \frac{48400 * 10}{100} = 53240$
