Answer:
i got A (0.088) i haven't found out if i got it right but thats what i got
Step-by-step explanation:
In such questions we mustuse examples.....
Let's imagine that the shortest size is 1
So as it is half of the second the second must be2
As it is the third of the longest size it must be 3
To find the perimeter we must add the three sides.
1+2+3=6
Therefore the perimeter is the double of the longest size
or
The longest size is half of the perimeter
We must take one or two more examples to be sure...
I will take another one
Let's imagine that the shortest size is 5
So as it is half of the second the second must be10
As it is the third of the longest size it must be 15
To find the perimeter we must add the three sides.
5+10+15=30
Therefore the perimeter is the double of the longest size
or
The longest size is half of the perimeter
I wish I helped you ;)
Answer:
26.4 km/hr
Step-by-step explanation:
Sofia and Diego drive to work.
For Sofia
We convert miles to km
Sofia drives 72 miles in 1.5 hours.
1 mile = 1.6 km
72 miles = x
x = 72 × 1.6 km
x = 115.2 km
We find the speed in km/hr
Speed = Distance /Time
= 115.2km/1.5 hours
= 76.8 km/hr
For Diego
Diego drives 126 km in 2 hour 30 min.
Speed = Distance/Time
Time = 2 hour 30 min = 2.5 hours
Speed = 126km/2.5 hours
= 50.4 km/hr
The difference between their average speeds in km/h is calculated as:
76.8 km/hr - 50.4 km/hr
= 26.4 km/hr
Answer:
of a sheet of paper
Step-by-step explanation:
Hi!
This isn't the easiest to explain with numbers but I'll do it with an example instead.
If you had 60 cookies and had to split it equally with you and one of your other friends, how would you do it?
You would do 
, right? Because you have 60 cookies and you're dividing it amongst 2 people.
It's the same idea here!
We take the number of sheets of paper, and we divide it by the number of people we have to share it with.
so we do . You don't even have to simplify in this case because this is a fraction and this is the simplest form of this fraction as well
I hope this made sense, let me know if you have any questions
