Answer:
The A ∩ B is {10, 40 ,60} .
Step-by-step explanation:
As given in the question
A = {10, 20, 30, 40, 50, 60}
B = {10, 40, 60}
The intersection A ∩ B of two sets A and B is represented the set that contains all elements of A that also belong to B .
Thus the A ∩ B becomes
A ∩ B = {10, 40 ,60}
Therefore the A ∩ B is {10, 40 ,60} .
$133.20
Since the amount of hours she worked isn't a whole number, we can first separate 18 and 1/2 and work the problem out one at a time.
1. Multiply 7.20 by 18 to get 129.60
2. Multiply 0.50 by 7.20 to get 3.60.
3. Add 129.60 and 3.60 together to get the answer, 133.20.
