Answer: John's share of the money is $18.75
Step-by-step explanation:
The total amount of money that was paid to John and Monica for their work is $41.25.
John worked 2.5 hours, and Monica worked 3 hours. This means that the ratio of the amount of time that each of them worked is
2.5 : 3
Total ratio is 2.5 + 3 = 5.5
If they split the money according to the amount of time each of them worked, then John's share of the money would be
2.5 / 5.5 × 41.25 = 103.125/5.5
= $18.75

Answer:
C
Step-by-step explanation:
When completing the square, we essentially want to create a perfect square trinomial by adding a constant.
If we have the following expression:
And we want to complete the square, we will need to divide the b-coefficient by half and then square it.
Thus, the added term should be:
In the given equation, we have:
The b term here is 8. Therefore:
The value we would add would be 16.
The answer is C.
Further notes:
To complete the square, add 16 like mentioned earlier. However, we also need to subtract 16 to balance things out:
The expression inside the parentheses is now a perfect square trinomial. Factor it:
And we are done!
