Answer:
117
Step-by-step explanation:
For every 3 zinc there would be 19 copper, and for every 19 copper there would be 3 zinc. There are 741 copper, so there would be 741 * 3 / 19 zinc, which turns out to be 117 zinc.
Answer:
Quadratic
Step-by-step explanation:
This is a quadratic equation because it's in the form of y=ax^2+bx+c
If it were linear, the graph would be a straight line and wouldn't contain a second degree term
If it were exponential there would be a growth or decay factor
I dont know lol lol lol lol
Answer:it wy + wz + xy + xz
Step-by-step explanation: i took it
The formula for this calculation is Future Value = Payment • [((1 + I)n - 1)/I], where I = interest rate, and n = periods.
In this case, P = $800/month, n = 18 months, and I = 6% (0.06) per year.
Since the information involves months instead of years, it is necessary to divide the interest rate by 12 to obtain the monthly rate. So, 0.06 ÷ 12 = 0.005
We can then enter the information into our formula to obtain:
FV = $800 • [((1.005)18 - 1)/.005]
FV = $800 • [(1.0939 - 1)/.005]
FV =$800 • (0.0939/0.005)
FV = $800 • 18.785
FV ≅ $15,028
