A rational number can be written as "a ratio of integers".
(That's a fancy name for "a fraction".)
Consider the universal set U and the sets X, Y, Z. U={1,2,3,4,5,6} X={1,4,5} Y={1,2} Z={2,3,5} What is (Z⋃X′)⋂Y?

X' = U - X
= {1,2,3,4,5,6} - {1,4,5}
= {2,3,6}
(ZUX') = {2,3,5} U {2,3,6}
= {2,3,5,6}
(Z⋃X′)⋂Y = {2,3,5,6} ⋂ {1,2}
= {2}
Answer:
V = 3538.78
Step-by-step explanation:
V = r²hπ
r= radius (7)
h = height (23)
π = pi (3.14)
V = (7^2)(23)(3.14)
V = 3538.78

Answer:
168
Step-by-step explanation:
The first equation given as 
Where a is the number of adults and b is the number of students
<em>Since, the number of students are given as 82, we can plug 82 into b and then do algebra and solve for a (shown below):</em>
<em>
</em>
<em />
<em>Thus, </em><em>168 adult tickets were sold</em>
