Answer:
You would need $23.87.
Step-by-step explanation:
Divide $20.46 by 6 which equals $3.41. Multiply $3.41 by 7 and you get $23.87.
Intersection means elements both have. Both sets have -1 but they have nothing else in common so the intersection is {-1}
Union means combining the sets so {-1, 1, 2, 3, 7} Note that I only wrote 1 twice. No duplicates allowed!
Answer:
the strand contains 28% of adenine.
Step-by-step explanation:
We have only four components, and we only know one of them:
Cytosine has a relation 1 to 1 with G, therefore the strand must contain the same amount of C as it posses G:
Therefore:
This is because the strain only contains those 4 components.
since A and T have also a 1 to 1 relation, we can state that A = T in quantity.
So:
