Answer:

100\ \text{ft/mi}

Step-by-step explanation:

Elevation of the head of the stream is 2,200 feet above sea level

Elevation of the mouth of the stream is 1,000 feet

Rise = 2200-1000=1200\ \text{ft}

Distance between the two points = 63360\ \text{ft}=\dfrac{63360}{5280}=12\ \text{mi} = Run

Gradient is given by

\dfrac{\text{Rise}}{\text{Run}}=\dfrac{1200}{12}\\ =100\ \text{ft/mi}

The gradient of the slope the stream is flowing over is 100\ \text{ft/mi}.

Answer: 16,940 from interest.
Explanation: The cost of it is 28,000 and when you figure out what 5.5% of that is it will come to be 1,540. Next you multiply 1,540 by the 11 years so it would come to 16,940.

Michael and his wife are each starting a saving plan. Michael will initially set aside $75 and then add $50.85 every week to the
lana [24]

Answer:

T = 75 + 116.9*N

Step-by-step explanation:

We have that the equation for Michael's savings is:

A = 75 + 50.85*N, where N is the number of weeks

And we have that the equation for his wife's savings is:

B = 65.95*N.

So, to find the total amount saved using both plans combined (T), we have to sum A and B:

T = A + B = 75 + 50.85*N + 65.95*N = 75 + 116.9*N

So the equation that relates T to N is:

T = 75 + 116.9*N
