Answer: the length is 6 feet. The width is 2 feet
Step-by-step explanation:
The garden pool is rectangular in shape.
Let L represent the length of the rectangular garden.
Let W represent the width of the rectangular garden.
The area of a rectangle is expressed as L× W. The area of the rectangular garden pond is 12ft^2. It means that
L× W = 12 - - - - - - - - - - 1
The length of the pool needs to be 2ft more than twice that width. This means that
L = 2W + 2 - - - - - - - - - - - 2
Substituting equation 2 into equation 1, it becomes
W(2W + 2) = 12
2W^2 + 2W = 12
2W^2 + 2W - 12 = 0
W^2 + W - 6 = 0
W^2 + 3W - 2W - 6 = 0
W(W + 3) - 2(W + 3) = 0
W - 2 = 0 or W + 3 = 0
W = 2 or W = - 3
Since the Width cannot be negative, then the width is 2 feet
Substituting W = 2 into equation 2. It becomes
L = 2×2 + 2 = 6 feet
We have been given that Tina designed an electric skateboard that has a speed of 4 miles per hour. Further we are given that in one hour it travels 4 miles, and in 2 hours it travels 8 miles.
We know that speed of any object can be found at any time, irrespective of it being a complete hour or a fractional hour. Therefore, speed of the electric skateboard is an example of continuous data.
The that in one hour it travels 4 miles, and in 2 hours it travels 8 miles have been given so that someone can easily confuse the speed of electric skateboard as a discrete data, but in actual speed of skateboard is a continuous data.
The way we always learned was

Answer:
≈ 113.1 in³
Step-by-step explanation:
The figure comprises of a cylinder and a cone.
- V cylinder = bh= πr²h
- V cone = 1/3bh = 1/3πr²h
Total volume is:
- V = π*2²*8 + 1/3π2²*3 ≈ 113.1 in³
It is: 91/200, because 45.5/100 is 45.5% as a fraction, but you have to make both the top a whole number, so you can multiply 45.5 by 2 to get 91, then also times the bottom by 2, and you get 200!
