Answer: 2:2 but if simplified it’s 1:1
Explanation:
Epsilon-delta would be the green letter that is used in the precision definition of a limit. (ε, δ).
Polyethylene terephthalate commonly abbreviated as PET
The percent composition of each element can be calculated as follows:
% composition = (mass of element / total mass) * 100
The total mass of the quarter is given to be 5.670 grams
Mass of Cu = 5.198 grams
Mass of Ni = 0.472 grams
Substitute in the above equation to get the mass percentage of each element as follows:
% of Cu = (5.198/5.670) * 100 = 91.675%
% of Ni = (0.472/5.670) * 100 = 8.325%
