Answer:
You will need 400 meters of cord.
Step-by-step explanation:
Since it's a square, we know the perimeter of the piece of land is 20 times 4, or 80. Because it is going around it 5 times, we just multiply 80 by 5 to get 400. You will need 400 meters of cord.
It is 8 units.
2πr=16π
r=16π/2π
r=8.
The least common multiple of 9, 3, and 18 is 18.
Convert 1/9 to 2/18.
Convert 2/3 to 12/18.
Then add the numerators:
2 + 12 + 5 = 19
So the answer is 19/18, or 1 1/18 if you prefer.
Answer:

Step-by-step explanation:
If y is the future value of the $1900 investment, in dollars, after t years at a rate of 3.75% per year, compounded annually. The exponential function that describes the relationship between the variables y and t is:

This relationship means that for every year t, the amount y will increase by a factor of 1.0375.
