Answer:
180
Step-by-step explanation:
1. Write a proportion.
=
2. Cross multiply.
6x60=360
360/2=180
x=180
OR
1. Write a proportion.
=
If you look at the bottom, since 2 times 30 is 60, 6 times 30 is 180, making the fractions equal.
Answer:

Step-by-step explanation:
The union of two sets P and Q, denoted as
is the set of all elements that are in the set P or in the set Q or in both sets P and Q.
Given:
P = {7, 8, 9, 10, 11}
Q = {1, 2, 3, 4, 5}
Then

When writing the union set, simply write all elements from both sets in on set.
Nothing to confuse. The number of partners are 3. $2.03 is the amount of tips they receive per hour. So devide $2.03 to get the amount of tip that one partner receives hourly, which is $0.68.
Now to create a function, it's clearly that the number of hours is the variable x so it would change depending on how many hours each employee has worked. So the equation will be :
y = 0.68x
Apply the number of hours of each employee and get the total of tip they receive per hour.
Edit : if the partners who are working is unknown you can write the equation based on this :
y = ((2.03)x)/n
n is the number of partners who are working so the amount of tip they will receive will depend on how many employees are working in the cafe.
Hope this helps !
