Given:
The statement is:
{5, 6, 7} = {5, 5, 6, 7, 7}
To find:
Whether the given statement is true or false.
Solution:
Two sets are equal if they have exactly the same elements.
The given set {5, 6, 7} has three elements and the set {5, 5, 6, 7, 7} has five elements but we known that all the elements of a set are distinct. It means, it has no repeated element.
Set {5, 5, 6, 7, 7} has three distinct elements 5, 6, 7. So,
{5, 5, 6, 7, 7} = {5, 6, 7}
Therefore, the given statement is true.
Answer:
Step-by-step explanation:
Answer:
D) 1/2
Step-by-step explanation:
<u>Dilation</u> : a type of transformation that makes the figure larger or smaller.
<u>Scale factor</u> : number or the conversion factor which is used to change the size of a figure without changing its shape.
Scale factor = dimensions of the new shape ÷ dimensions of the original shape
Given:
- Length of new figure P'Q' = 3 units
- Length of original figure PQ = 6 units
Therefore, scale factor = 3 ÷ 6 = 1/2
