Okay so you start with 1/3. Fractions are just a fancy way of saying (in this case) 1 divided by 3. And if you do that you'll get .3333. After that to make it a percent you just move the decimal spot in front of the 3 over two places, getting 33.33%. With mixed numbers it's just one more step. So in this case 2 1/5 you would have to make it a normal fraction first so I got 11/5ths and here's how I got it. 2 1/5. Multiply the denominator (5) with 2. You get 10. Then add the numerator (1) to get 11. Tack on the 5 and you get 11/5. To make this a percent just do the same thing as the normal fractions... 11 divided by 5 to get 2.2. Move the decimal two places to the right to get 220%. Try the rest on your own and if you get confused ask... :)

Select the conjecture with the rephrased statement of proof to show the diagonals of a parallelogram bisect each other.
const2013 [10]

Considering the given figure, the conjecture with the rephrased statement of proof to show the diagonals of a parallelogram bisect each other is: In parallelogram EFGH show EK is congruent to KG and F.K is congruent to KH

<h3>How to determine the correct rephrase of the proof about parallelogram diagonals</h3>

The diagonals refer to the lines running between the two opposite ends of the parallelogram

Bisecting means sharing into two equal parts

congruent means a copy that is equal in dimension hence can be used in place of the other image  

The diagonals of a parallelogram bisect each other means that the diagonals cut each other to form two equal parts such that each part is congruent to each other.

When using the given diagram to determine the area of the pentagon by decomposition, which statements are correct?:
pogonyaev

Answer:

Options (B) and (E)

Step-by-step explanation:

Area of ΔABC = \frac{1}{2}(\text{Base})(\text{Height})

                        = \frac{1}{2}(14)(6)

                        = 42 in²

Area of trapezoid ADEC = \frac{1}{2}(b_1+b_2)h

[Here, b_1 and b_2 are the parallel sides and 'h' is the height of the isosceles trapezoid given]

= \frac{1}{2}(10+14)(8)

= 96 in²

Area of the pentagon = Area of triangle ABC + Area of trapezoid ADEC

                                    = 42 + 96

                                    = 138 in²

Therefore, Options (B) and (E) are the correct options.
