He see a circle, so you need to find the area.
A = π * r²
A = π * 12²
A = 3.14 * 144 =
A = 452.16 miles²
0.9/5=0.18
2.4/12=0.2
so the first one is better
Answer:
Height of the awning = 9.52 feet
Step-by-step explanation:
For better understanding of the solution, see the attached diagram of the problem :
According to the figure, AB is the height of the awning
Now, the base of awning will be perpendicular to the building
⇒ m∠ABC = 90°
In ΔABC, By using angle sum property of a triangle
m∠ABC + m∠ACB + m∠BAC = 180°
⇒ m∠ACB = 50°

Hence, Height of the awning = 9.52 feet
Answer:y=6.61,x=-6.46
Step-by-step explanation:
3x+7y=-26(×5)
-
5x+3y=-14(×3)
=15x+35y=-130
-
15x+9y=-42
subtracting the 2 equations =15x-15x+35y-9y=-130-(-42)
=26y=172
y=172÷26
y=6.61
substitute y in the first equation=3x+6.61=-26
3x=-26+6.61=-19.39
x=-19.39÷3
x=-6.46
Answer:
B
Step-by-step explanation:
There isn't any number that x can't be. Start with a graph to show how this could be so.
It is easy to see that x > 0 gives a line that goes very near the x axis. It is not quite so easy to see that it never touches the x axis. But if you recreate the graph in Desmos, you will see that is true if you spread the x's out.
It is not quite so easy to see that when x<0 the graph tips upward very quickly but again if you move the values of the axis around you will see there is no value that x cannot be.
