The correct answer is: D. (A u B)
Step-by-step explanation:
The operations on sets are of two types
1. Union
2. Intersection
In union, the elements of both sets are combined in one set while in intersection only common elements of both sets are considered.
Here,
"all of the elements which are in set A or B"
This statement means the elements of both sets have to be considered. The word "Or" points to the combination of both sets as an elements belonging to any of the set will be considered. So union operation will be used.
Hence,
The correct answer is: D. (A u B)

d = dimes
q = quarters
d+q = 38 coins
q=38-d
0.25q + 0.10d=6.95
0.25(38-d)+0.10d=6.95
9.5-0.25d+0.10d=6.95
-015d=-2.55
d=-2.55/-0.15 = 17
q=38-17 =21
21*0.25 =5.25
17*0.10 = 1.70
5.25+1.70 = 6.95
she had 21 quarters and 17 dimes
Answer:
E. 1,700 is your answer.
Step-by-step explanation:
What you do is you add 668 + 575 + 453 together.
668 + 575 + 453 = 1,696.
The hundreds place is the 9. Since the 9 is bigger than 4 it gets rounded up. That means the 6 in front of the 9 becomes a 7 and 9 and 6 become a zero.
E. 1,700 is your answer.
