Answer:
27.4 yards
Explanation:
The diagonal of a rectangle, one of it's length and one of it's width will form a right angle triangle
Let
Width = x
Length = 2x
Diagonal = 80 yards
c^2 = a^2 + b^2
Where
c= diagonal
a= length
b= width
c^2 = a^2 + b^2
80^2 = (2x)^2 + (x)^2
80^2 = 2x * 2x + x^2
80^2 = 4x^2 + x^2
6,400= 5x^2
Divide both sides by 5
x^2= 6400 / 5
= 1280
x^2 = 1,280
Find the square root of both sides
√x^2 = √1,280
x= 35.8
How many yards, to the nearest tenth of a yard, does a person save by walking diagonally across the land instead of walking its length and its width?
Yards saved= (Length + width) - diagonal
= (2x+x) - 80
= {2(35.8) + 35.8} - 80
= (71.6 + 35.8) - 80
= 107.4 - 80
= 27.4
Yards saved = 27.4 yards
The correct answer to this open question is the following.
The Roanoke River has tributaries that come from both the Appalachian and Cordillera Mountains.
The Roanoke River runs from the south part of the state of Virginia to the northeastern region of the state of North Carolina. It is one of the most important rivers in what is known as the coastal plain, next to the Appalachian Mountains, with its more than 400 miles.
