Answer: Length of fence along the diagonal is 28.3 feet.
Step-by-step explanation:
Since we have given that
The Blackburn family has a square field ,
Area of square = 40000 ft square
As we know the formula,
Area of square = Side x Side
40000 = slide

20 ft = Side
But Blackburn wants to put a fence diagonally through the field ,
As we know the formula for "Diagonal of side" i.e.
Diagonal of square 
Diagonal of square 20
So,
Length of fence along the diagonal = 20 x 1.41 = 28.3
Hence, length of fence along the diagonal is 28.3 feet.
Hope this helps!
Answer:
The player answer correctly 30 questions
Step-by-step explanation:
First we have to develop the information that gives us as 2 equations
x = correct answer
y = incorrect answer
z = score = 40
h = total answer = 50
2x - y = z x + y = h
2x - y = 40 x + y = 50
we clear the x of one equation and replace the value of x in the other equation
x = 50 - y
2x - y = 40
2(50 - y) - y = 40
100 - 2y - y = 40
-3y = 40 -100
y = -60/-3
y = 20
x = 50 - y
x = 50 - 20
x = 30
Answer:
Answer is 105 in^2
Step-by-step explanation: Area of rectangle= length X breadth
= 8X12
=96in^ 2
Area of triangle= 1/2 X base X height
= 1/2 X 3 X 6
= 9 in^2
Area of irregular pentagon = area of triangle + area of rectangle
= 96+9
=105 in ^2
Answer:
106°
Step-by-step explanation:
These angles are alternate interior, therefore they are equal to each other.
