10/12 in simplest form is 5/6.
Equivalent ratios would be 15/18, 20/24, and 25/30.
The rest is easy, give it a try.
Every mixed number is (a whole number) + (a piece of another one).
So every mixed number must be bigger than ' 1 ', because ' 1 ' is the
smallest whole number.
77/200 is less than ' 1 ', because the numerator is less than the
denominator. So it doesn't have what it takes to be a whole number.
Every fraction is a short way to write a division problem. It means
(the top number) divided by (the bottom number).
When you actually do the division, the answer is the decimal form
of the fraction.
When you divide 77 by 200 , you get 0.385 .
To get the perimeter of the trapezoid, we will add the lengths of the 4 sides together.
So, first we will need to get the length of each side.
Base of trapezoid = 8 - 2 = 4 unitsThe upper edge of the trapezoid = 6 - 4 = 2 unitsNow, for the two side edges, we can note that
they are both equal. So, we need to get only one length (as the other would be the same). I will get the length of the left side.
Coordinates of the start point are (2,4) which represent (x1,y1)
Coordinates of the end point are (4,9) which represent (x2,y2)
To get the distance between the two points, we will use the rule attached in the image below as follows:
distance = sqrt ((4-2)^2+(9-4)^2)
distance = √29
Therefore, each of the side edges equal √29 unitsFrom the above, we can now easily get the perimeter as follows:perimeter = 6 + 2 + √29 + √29
perimeter = 8 + 2√29 units
Based on the above calculations, the best choice would be:D. 8 + 2√29 units
observe that the triangles KLM and MNL are similar. so,
(MN/c) = (c/b)
so, MN =12*12/27.73 = 5.19
