Bonjour,
Soit c le côté de l' hexagone.
On a 5.2²+(c/2)²=c²
==>c²=5.2*4/3
c²=104/15
c=√(104/15)=2,6331223544175332023251281391631...
Aire de l'hexagone= 5.2*c/2*6=41,076708728913517956271998970944
Je me suis permis de répondre en Français car l'énoncé était en Espagnol. (Thanks to Google translator)
Simple interest is where 3% of the original value is added on each year
goal number = $102
original number = $680
3% of $680 can be found by getting 1% and multiplying by 3
100% = original number = $680
100% / 100 = 1% so $680 / 100 = $6.80 = 1%
3% = $6.80 * 3 = $20.40
so each year the money rises by $20.40
to find out how many years it would take to get to $102:
$102 / $20.40 = 5 years
Answer:
The change for the input would be 1, and the change for the output would be 0.35. The rate of change should be 0.35 also.

We can compare by converting Johnny's reading time into the same unit of Jacky's, hours.
There are 60 minutes in an hour, so use this:

15 < 20, so Johnny read faster. This is 5 pages faster per hour than Jacky.
