Answer: 6 feet x 3 feet
Step-by-step explanation:
Let the height be given by= x
The length is= 6x -2 (1) from both sides= 6x-2
The width is= 3x-2(1) from both sides= 3x-2
The total volume= length * width * height
4=(6x-2)*(3x-2)*x
Solving we get,
x=1 and other factor is not the valid option.
So the outer dimensions should be 6 feet x 3 feet
the answer is b i did the math it checks out
P=0.15
P^ is the sample proportion which comes from the data
In this case the p^=12/50=0.24
Answer:
3 1/3 feets
Step-by-step explanation:
Given that:
Height of aquarium = 1 3/4 feets
Area of aquarium = 5 5/6 ft²
The length of aquarium = x
Aquarium is shaped in the form of a rectangle :
Area of a rectangle = Length * width
5 5/6 = x * 1 3/4
35/6 = 7x/4
Cross multiply :
7x * 6 = 35 * 4
42x = 140
x = 140 / 42
x = 3 14/42
x = 3 1/3 feets
Hence, Length of the back of aquarium is 3 1/3 feets
