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 :)
Answer:
248 degrees
Step-by-step explanation:
Since segment PL is congruent to segment LK, their corresponding arcs are also congruent. Knowing this, we can set 11x - 10 and 9x + 2 equal to each other:
11x - 10 = 9x + 2
2x = 12
x = 6.
So, plugging in 6 into the value of x for both minor arcs gives us that arc PMK is 112 degrees. Since the whole circle is 360 degrees, major arc PNK is 360 - 112 = 248 degrees.
Hope that helped! :)
The geometric mean of two numbers is the square root of their product.
sqrt{4 • 12}
sqrt{48}
sqrt{16} •sqrt{3}
4•sqrt{3}.
The geometric mean of 4 and 12 is
4•sqrt{3}.
The answer is 16 inches :) hope this helps
