30 is what percent of 80?
2 answers:
Let's see what we're working with!
Always remember the word "of" means multiply in mathematical terms
Our work!
30(80) = ?
30 ÷ 100 =
but the result of this would have to be 0.3
So, the problem becomes: 0.3 (80)
The answer of that ↑ would be 24
Finally, we get to your answer!
If you do it my way your answer would be 24 but if you do the other way your answer would be 37.5 if that makes sense
Good Luck!

Answer:
15 is the total number of animals for which (p ∨ q) ∧ r true.
Step-by-step explanation:
From the diagram it is clear that
p contains {2, 5, 8, 9}
q contains {2, 4, 7, 5}
r contains {2, 4, 6, 9}
p ∨ q is the union of p and q which include all the animals which are in p, in q, or in both p and q.
Note: p ∨ q can not have duplicate animals
So,
p ∨ q = {2, 4, 5, 7, 8, 9}
(p ∨ q) ∧ r contains the animals which need to be common in both (p ∨ q) and r.
As
p ∨ q = {2, 4, 5, 7, 8, 9}
r = {2, 4, 6, 9}
So,
(p ∨ q) ∧ r = {2, 4, 9}
As
Therefore, 15 is the total number of animals for which (p ∨ q) ∧ r true.
