Looking at this in terms of sets, let's call O the set of all owls, and F the set of all things that can fly. What this original statement is saying every animal that's a member of the set of all owls is also a member of the set of all things that can fly, or in other words, O⊂F (O is a subset of F). Negating this tells us that, while there's <em>at least one</em> element of O that also belongs to F, O is not contained entirely in F (O⊆F, in notation), so a good negation or our original statement might be:
<em>Not all owls can fly.</em>

Answer:
Step-by-step explanation:
Area = 3.14r^2
Area = 3.14(5)^2
Area = 3.14(25)
Area = 78.5
 
        
             
        
        
        
Answer:
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

Answer:
 K = 3
 T = 2
And
 H = 12
Step-by-step explanation:
3k = 9
k = 9/3
k = 3.
 3k =k + 3t
subtitute value of k
3×3=3+3t
9-3=3t
6/3=t
t=2.
2k + h =18
2×3+h=18
h=18-6
h=12...
