The scale factor = 3.00
The scale factor of a circle to another is the ratio of their radii
Radius of the first circle = 9 in
Diameter of the second circle = 6 in
Radius = Diameter / 2
Radius of the second circle = 6 / 2
Radius of the second circle = 3 in
Scale factor = (Radius of the first circle) / (Radius of the second circle)
Scale factor = 9/3
Scale factor = 3.00 (2 decimal places)

Answer:
6
Step-by-step explanation:
2904 = 2 x 2 x 2 x 3 x 11 x 11 = (2 x 3) x (2 x 2) x (11 x 11)
=> Smallest number by which 2904 must be divided so that it becomes a perfect number MUST belong to
{(2 x 3), (2 x 3) x (2 x 2), (2 x 3) x (2 x 2) x (11 x 11)} = {6, 24, 2904}
It is easy to see that the solution is 6
(this is the smallest number in collection above)
The answer is < because you must find a common denominator so it’s this 3/4<31/40
A square rotated about its center by 360º maps onto itself at 4 different angles of rotation. You can reflect a square onto itself across 4 different lines of reflection.
<h3>What is the rotation Transformation?</h3>
A rotation is a transformation in which the object is rotated about a fixed point. The direction of rotation can be clockwise or anticlockwise.
A square is a geometric figure which has all its four sides equal and all its interior angles are right angles (90°) .
Therefore, it can be rotated about its center by (360°).
It maps onto itself at 4 different angles of rotation (at every 90°).
Thus, we can reflect a square onto itself across 4 different lines of reflection (2 across the non-parallel sides and 2 across the vertices of the square).
Thus, we can conclude that A square rotated about its center by 360º maps onto itself at 4 different angles of rotation. You can reflect a square onto itself across 4 different lines of reflection.
