The highlighted sector is exactly 3/4 of the circle area, because 
is 3/4 of 
which is a complete rotation.
Since you are given the radius, you can compute the area as
So, 3/4 of this area would be 
squared cm.
The remaining sector, of course, is 
squared cm.
(From top to bottom) wrong, right, right, right, wrong. This is because a irrational*an irrational number is rational, but a rational*an irrational is an irrational number
He sold 12 candy bars.
3x + 5y = 76
X + y = 20
2y= 16
Y= 8
X= 20 - 8= 12
Hope this helps.
Answer:
A negative exponent involves taking the inverse of the number, then multiplying it by itself once it's in the denominator of the fraction.
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.
