Width = 10 feet
Length = 40 feet
================================================
Explanation:
W = width
L = 4W = four times the width = length
P = perimeter
P = 2*(W+L)
P = 2*(W+4W)
P = 2(5W)
P = 10W
The perimeter is 100 feet.
P = 100
10W = 100 .... plug in P = 10W
W = 100/10 .... divide both sides by 10
W = 10
The width is 10 feet.
L = 4W
L = 4*10
L = 40
The length is 40 feet.
-----------------
Check:
P = 2(L+W)
P = 2(40+10)
P = 2(50)
P = 100
or another way to check is to add up the four sides {10, 40, 10, 40}
10+40+10+40 = 50+50 = 100
This confirms the answer.

Answer:
20 degrees
Step-by-step explanation:
A triangle's angles should 180 degrees added together, so 90 + 70 = 160, leaving 20 for the last angle.
Answer: 
Step-by-step explanation:
It is important to remember that, by definition, proportional relationships have the following form:
Where "k" is the constant of proportionality.
We know that Maddy assume that the relation between the volume and the weight is proportional.
Then, let be "V" the volume in liters and "w" the weight in kilograms.
We can write the following equation:
So, if the boat of 555 liters weights 7.5 kilograms, we can find "k":
In order to solve the exercise, substitute the value of "k" and 
into the equation and solve for "w". Then:
