12.5% 80-70=10 then divide 10\80 to get .125 , then multiply by 100 to get 12.5%
Answer:
A. 44
Step-by-step explanation:
The area of a trapezoid is 
, where b_1 and b_2 are the top and bottom bases, and h = height. We are given the bases as 8 and 14, and the height as 4.
Therefore, the answer is A. 44.
Answer:
The perimeter = 6r
Step-by-step explanation:
∵ the regular hexagon consists of 6 equilateral triangle
∴ The 3 sides of each triangle are equal
∵ Regular hexagon is inscribed in a circle
∴ Each vertex of the regular hexagon lies on the circle
∴ the radius of the circle is the the side of the triangle
∴ The length of each side of the triangle = r
∵ The regular hexagon has 6 equal sides all of them are the bases of the six equilateral triangles
∴ The perimeter of hexagon = 6 × r = 6r
Your answer should be 2 over 41, because:
41/2 = 20 1/2
20 1/2 = 20.5
The denominator has to be a whole number, so 20.5 times 2 = 41
Now all you have to do is add the 1 as the numerator, turning it to a fraction
And now you have 2 over 41
