Area of the base of the model
3*2 = 6 square feet
Since the actual building 120 times bigger than the model, it should be multiplied with 120
6*120 = 720 square feet
The answer is 14 beachside every 10 hours trained, you get an extra 100 dollars.
The Rule of 72 is a shortcut method to find the number of years to double your investment. This is only an estimation. This can be done by dividing 72 by the annual interest rate.
However, you are given a nominal rate since it is compounded annually. Let's convert this by this equation:
annual rate = (1+i/m)^m - 1, where m is the number of periods in a year. Thus, m=2
annual rate = (1 + 0.065/2)^2 -1 = 6.61%
Applying Rule of 72,
72 ÷ 6.61% = 10.89
This is where I found a problem. The answer here just directly divided 72 by 6.5% which will equal to 11.1 years. This is not accurate, since the given interest is compounded semi-annually. That is not an annual interest rate.
Nevertheless, the answer is still close to letter A.) 11.1 years.
Answer:
Step-by-step explanation:
x-y=5
-x+y=5
or x-y=-5
so it is a system of two parallel lines.
so no solution.
or they do not intersect atmany point.
C is your answer.
It contains the proper points and form. A is not in point-slope form and B has the incorrect slope.
