Answer:
Step-by-step explanation:
The width of the rectangle = x
Therefore the length of the rectangle = 2x, as it is twice its width
We know that the perimeter of a rectangle = 2 × （length + width）
So since the perimeter equals to 30, then we can form the equation:
2×(2x+x) = 30
2×(3x) = 30
6x = 30
x = 5
width of the rectangle = x = 5
length of the rectangle = 2x = 2×5 = 10
If there is an unit which is in the question, remember to add it to the end of the answer. As you have not written any units in the posted question, I will leave it as it is.
Hope this helps :)

x+8 10
-----=----
2x-5 14
10(2x-5)=14(x+8)
20x-50 = 14x+112
20x-14x = 112+50
6x = 162
x= 162/6
x=27.....

The answer for this will be letter d. C = 22π and A = 121π. This is computed using the formula of C= Dπ which is C = (22)π. On the other hand, the area of this circle is computed by using the formula A = <span>πr^2. This is computed as follows:
A = </span><span>πr^2
A = </span><span>π (22/2)^2
A = </span><span>π (11)^2
</span>A = 121<span>π</span><span>
</span>
The radius of the base of the container:
20/(2*3.14)=3.18cm
Area of the base:
3.14*3.18*3.18=31.8cm square
The toll of the container :
5453/31.8
=171.5cm
Answer:
0.185185185185185185.........
Step-by-step explanation:
i used a calculator, to the nearst tenth is 0.18 to the nearest 100th is 0.185 also the 185 is repeating so u put a line over the numbers 185
