Answer:
140 feet
Step-by-step explanation:
You will need to find the perimeter of the backyard to find how many feet of fencing will be needed
the formula for perimeter is: 2l+2w
So 2 times 30 is 60
with 2 times 40 80
60+80 is 140
Thus you will need 140 feet to cover the backyard
Hope this helps!
Volume = s*s*s = s^3
A cube have equal sides, the length is s the width is s and the height is s.
216 = x^3
x = cuberoot of 216
x = 6 units
Answer: 9/19
Explanation: add all the die to find the total amount (19) so we know that 9 of the 19 die a green, therefore to probability is 9/19
Answer: 6units
Step-by-step explanation:
Since it is a regular polygon, and it has 3 equal sides it means the polygon is a quadrilateral.
From the diagram,
5 - 2x = -4x + 9 ( side of quadrilateral )
Solving for x in the equation
-2x + 4x = 9 - 5 ( collection of like terms in simple linear equation )
2x = 4
Divide through by the coefficient of x which is 2
x = 2.
Therefore, the perimeter of the polygon which equals to the total length of the polygon is
Perimeter = 2 + 2 + 2
= 6units
Answer:
Yes, 39/100 is the correct answer. You can't necessarily simpify it any further than that
