Answer:
={6,7,8,9,10}.
Step-by-step explanation:
We have an empty set: M={} and the set N={6,7,8,9,10}.
The union of these two sets are elements in M or N or both.
Since the M is a null set, 
Therefore: ={6,7,8,9,10}.
The union for the given sets is {6,7,8,9,10}.
Answer:
4 yd².
Step-by-step explanation:
From the question given above, the following data were obtained:
Length (L) = 2⅔ yards
Width (W) = 1½ yards
Area (A) =.?
The area of the piece of fabric that Roberto needs can be obtained by using the formula for calculating the area of a rectangle. This is illustrated below:
Area (A) = Length (L) × Width (W)
A = 2⅔ × 1½
A = 8/3 × 3/2
A = 8 × ½
A = 4 yd²
Thus, the area of the piece of fabric that Roberto needs is 4 yd²

Step-by-step explanation:
6/4 = 1.5
10/4 = 2.5
Therefore the sequence is 1, 1.5, 2.5, 3
So the common difference is either 0.5 or 1
