Answer:
There are 286 possible combinations
Step-by-step explanation:
To solve this problem we must use the formula of combinations.
Where n is the number of players that there are and elect r of them
In this case there are 7 + 6 = 13 players and you choose 10 of them
Then we look for 13C10
There are 286 possible combinations
Yes they are equivalent 18:9 simplified by 9 is 2:1
Answer:
Step-by-step explanation:
G and H are parallel lines and J is the transversal.
∠FDN is corresponding angle with ∠HKJ.
The corresponding angles postulate states that, when two parallel lines are cut by a transversal, the resulting corresponding angles are congruent.
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.
