mr.campbell has a square garden with an area of 256 square feet. he wants to put a fence along 3 sides of the garden. how many feet of fencing will he need?
Answers
Solution:
It should be noted:
Area of square garden = L² = 256Square root both sides of the equation to find the length of the square garden. Then, use the length of the square garden to calculate the length of fence required for 3 sides of the garden.
Square root both sides.
√L² = √256=> L = 16Multiply the length by 3.
3L = 16 x 3 = 48 feetThus, Mr. Campbell will need 48 feet of fencing.

the width of the rectangle fence is 5 ft less then the length if the length is decreased by 3 ft and the width is increased by 1 ft the area limited by the old fence will be the same as the area of the original fence
Answers
Answer: Length is 6 ft and
Width is 1 ft
Step-by-step explanation: The first clue we have been given is that the width of the rectangular fence is five feet less than it's length. So, if the length is L, the width is L - 5. From that bit of information on we can calculate the area if he rectangular fence as
Area = L x W
Area = L x (L - 5)
Area = L² - 5L
Also, the question further states that if the length is decreased by three feet (L = L - 3), and the width is increased by one foot (W = {L - 5} + 1 and that becomes L - 4), the area of the new enclosure would be the same as the first one. The area of the new enclosure would be given as
Area = L x W
Area = (L - 3) (L - 4)
Area = L² - 4L - 3L + 12
Area = L² - 7L + 12
Since the question states that the area of the original fence and the new one are the same, we can now write the following expression
L² - 5L = L² - 7L + 12
(That is, area of the first set of dimensions equals area of the second set of dimensions)
L² - 5L = L² - 7L + 12
By collecting like terms we now have
L² - L² - 5L + 7L = 12
(Note that when a positive value crosses the equation to the other side, it becomes negative and vice versa)
2L = 12
Divide both sides of the equation by 2
L = 6
Having calculated the length of the rectangular fence as 6 ft, the width is now derived as
W = L - 5
W = 6 - 5
W= 1
Therefore, the length is 6 ft and the width is 1 ft.

Answers
Answer:
The difference between the volume of the prism and the volume of the storage container is 35 - 31.25 = 3.75 cm³
Step-by-step explanation:
Given : A rectangular prism has a length of cm, a width of cm, and a height of 5 cm.
Justin has a storage container for the prism that has a volume of 35 cm³.
We have to find the difference between the volume of the prism and the volume of the storage container.
Since the volume of the rectangular prism is given as the product of its length , width and height.
Mathematically written as,
Volume of rectangular prism = Length × Width × height
Given - length = cm,
width = cm,
and height = 5 cm.
Thus, Volume of rectangular prism =
Simplify, we have,
Thus, Volume of rectangular prism = cm³
Thus, the difference between the volume of the prism and the volume of the storage container is 35 - 31.25 = 3.75 cm³

Answer:
23/9
Step-by-step explanation:
Explanation:
We first let 2.5 (5 being repeated) be x
Since x is recurring in 1 decimal places, we multiply it by 10.
10x = 25.5
Next, we subtract them.
10 x - x = 25.5 - 2.5
9x = 23
Lastly, we divide both sides by 9 to get x
as a fraction.
x =23/9

20.00 for 1 pack of screws
The brothers have 890.20 dollars. Do they have an enough to build the shed?
Explain your answer and show your work.
Answers
Answer:
They need $910 in total for all the supplies but they only have $890.20, so no they don’t have enough.
Step-by-step explanation:
30 pieces of plywood x $25.00 per ply wood = 30 x 25= 750
20 packs of bricks x $2 per brick= 20 x 2= 40
6 pack of screws x $20 per pack = 6 x 20= 120
750 + 40 + 120= 910
