It would be 0.75 as a decimal or 3/4
Answer:
Given the statement: Crater Lake in Oregon in shaped like a circle with a diameter of about 5.5 miles.
Area of circle is given by:
![A = \pi \frac{d^2}{4}](https://tex.z-dn.net/?f=A%20%3D%20%5Cpi%20%5Cfrac%7Bd%5E2%7D%7B4%7D)
where
A represents the area of a circle
d represents the diameter of a circle.
then;
It is given that Surface of Crater lake is shaped like a circle.
Substitute the given values, we have;
Area of a circle = ![\pi \frac{(5.5)^2}{4}](https://tex.z-dn.net/?f=%5Cpi%20%5Cfrac%7B%285.5%29%5E2%7D%7B4%7D)
=
square miles
therefore, the area of a surface of a crater lake is, 23.74625 square miles.
Answer:
r = -4
Step-by-step explanation:
If M is the midpoint of DE, that would mean that the distance from M to D and M to E would be the same.
This creates the equation 1-8r=13-5r.
Now it's just simple algebra.
You add 8r to both sides, creating 1=13+3r. Then, you subtract 13 from both sides, getting 3r=-12. Dividing both sides by 3 and solving for r, you get r=-4.
Checking our answer, you see that 1-8(-4)=1-(-32)=1+32=33, and 13-5(-4)=13-(-20)=13+20=33.
Answer:
Step-by-step explanation:
what is she considering? I would need more information to complete the probolem
Slope of -2, (1,5)
y = mx + b
slope(m) = -2
(1,5)...x = 1 and y = 5
now we sub and find b, the y int
5 = -2(1) + b
5 = -2 + b
5 + 2 = b
7 = b
so ur equation is : y = -2x + 7
The approximation method used to estimate a point between 2 given points is called linear interpolation. The approximation method used to estimate a point that does not lie between 2 given points is called linear extrapolation.A linear function has the form f(x) = mx + b. Its graph is a line that has slope m and y intercept at (0,b).
