The surface elevation of Lake Powell is decreasing at the rate of 77.2 feet per year.
<h3>What is the rate(slope) at which the sea is decreasing?</h3>
The rate at which the surface elevation of the Lake Powell is decreasing can be determined by calculating the slope(steepness) of the sea.
The slope can be given as:
Slope (Δm) = rise/run
Slope (Δm) = Δy/Δx
slope (Δm) = y₂ - y₁/x₂-x₁
slope (Δm) = 3263.4 - 3881/2006-1998
slope (Δm) = -617.6/8
slope (Δm) = -77.2
Therefore, we can conclude that the surface elevation of Lake Powell is decreasing at the rate of 77.2 feet per year.

If you want to preserve all of the significant figures, then it's 9.00008 x 10^6 .
Answer:
they are all in order 1A-1b, 2a-2b,3a-3b
Step-by-step explanation:
Divide to undo the multiplication of n times 72. Move the decimal point two places to the right to write the decimal as a percent. You can estimate to see if the answer is reasonable. Use 10% and 20%, numbers close to 12.5%, to see if they get you close to the answer.
Hope this helps
Two burgers for 6.25 is just multiplied twice, which is 12.5. Two orders of fries for 1.25 is 2. So 2 plus 12.5 is 12.7, and 12.7 with a 11% tip is 14.09700. My bad if it’s incorrect, good luck
