Area of cylinder = pi · r^2
A
Don't forget that you can also pull out an x besides the 10. The expression should look like this.
A(x) = 10x(x - 5)
The GCF is 10x
B
The area of the Bedroom = 10x ( x - 5)
If the length = 5x then the width is
A/L = 10x (x - 5)/(5x)= 2*(x - 5)
C
Now they are changing the Length to the GCF. We determined in A that the GCF = 10x
This time A/L = 10x(x - 5)/10x = (x - 5)
So the width = x - 5
Answer:
-3/1
Step-by-step explanation:
The slope can be found by putting the rise over the run.
Pick 2 points on the graph that intercept the line.
I'll pick (0,2), and (1,-1)
Look at the rise.(How many places it goes up or down)
The rise vertical distance(rise), between the two points is -3.
Now look at the run(the horizontal distance.) It's 1.
Rise/Run = -3/1 AKA -3
2/3÷4/5
2/3*5/4
10/12
5/6
Hope this helps :)
The mean is the average.
Let A = mean
A = (18 + 14 + 9 + 6 + 3)/5
A = 50/5
A = 10
Ellie's mean time is 10 seconds.
