Answer: there are 8 key chains Ella can buy.
Step-by-step explanation:
Since we have given that
Ella bought some key chain and spent a total of 24.
Each key chain cost the same whole dollar amount she bought between 7 and 11 key chains.
As we know that between 7 and 11, there is only 1 number which is factor of 24 i.e. 8
Hence, there are 8 key chains Ella can buy.
True, A method of creating a geometric figure that is mathematically precise by using a compass and straightedge is called drawing or copying.
Given that,
A statement is given we have to determine whether the statement is true or false.
In congruent geometry, the shapes that are so identical. can be superimposed to themselves.
Here,
The statement is given is, "A method of creating a geometric figure that is mathematically precise by using a compass and straightedge is called drawing or copying."
The given statement si true because the statement is the true definition of drawing or copying, drawing or copying are the methods of creating a figure or portrait of something in precise order.
Thus, the given statement is true.

true
Step-by-step explanation:
Answer:
The area of B is 8 cm²
Step-by-step explanation:
From the diagram, we can tell that the scale factor is 2 because the length of A is 6 cm and the length of B is 12 cm so the scale factor is 2. Since diagram A's area is 4 cm², all we need to do is multiply the diagram A's area by 2. That gives diagram B's area which is 8 cm²
