I think the correct answer would be D. The two parallelograms are congruent because a rotation does not change size and shape.

Answer: D) The two parallelograms are congruent because a rotation does not change size and shape.


Step-by-step explanation:

Rotation transformation is a rigid transformation which create the image of a figure with same shape and size by rotating it by some degrees about the the center of rotation. It doesn't change size and shape of the figure.

When we rotate a figure about a point and if it doesn't change the shape then it is called rotational symmetry.

Therefore, only D is the right option.

<u>Answer:</u>

c=  -1/2

<u>Step-by-step explanation:</u>

Let's solve your equation step-by-step.

4 /3  = −6c − 5/ 3

Step 1: Simplify both sides of the equation.

4 /3  =−6c +  −5 /3

Step 2: Flip the equation.

−6c +  −5 /3  =  4/3

Step 3: Add 5/3 to both sides.

−6c +  −5 /3  +  5 /3  = 4/3  +  5 /3  −6c

=3

Step 4: Divide both sides by -6.

−6c  −6   =  3 − 6 c =  −1 /2

A circular tabletop has a circumference of 94.2 inches. What is its approximate area?
MrRa [10]

Answer:

1st choice : 706.5 square inches

Step-by-step explanation:

circumference is pi times diameter

divide 94.2 by pi to get diameter = 29.9847912785

diameter 29.9847912785 divided by 2 is

14.9923956393 which is the radius

area is pi times radius times radius again

pi times 14.9923956393 times 14.9923956393 =

706.141834613
