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)
Since the question is asking for the time units to be in hours, you want to convert 30 minutes to an hour; 0.5
We’re able to use the basic motion formula for velocity to work out this question.
Velocity = distance / time
Velocity = 5 / 0.5
Velocity = 10km/h
Therefore, Stanley’s average speed was 10 kilometres per hour. :)
Answer:
x=4
Step-by-step explanation:
3x-3=9
+3=+3
3x=12
3x=12
divide both sides by 3
leaving x by itself
12/3=4
x=4
Answer:
2km/m
Step-by-step explanation:
6 laps = 10km
(because 3 x 2 = 6 and double 5km as well)
Distance divide time = speed
20 mins divided by 10km = 2km per minute
