Answer:
57 square inches
Step-by-step explanation:
First consider that a 45 degree sector of a circle is 45/360 of the area of the full circle from which it is cut. This comes out to 1/8 of the full circle area.
The area of a circle of radius 12" is A = π(12 ")^2, or A = 144π.
The area of the sector in question is 1/8 of that, or
A = (1/8)(144π), or A = 18π square inches, or approximately 57 square inches.
22 miles,
30miles - 8 miles = 22 miles
Mikes trip to work is 22 miles farther than sam’s
There are several ways you can go about solving this. The easiest way is to graph it with desmos. But I'll show you how to do it algebraically.
So what it means when it says the point of intersection is what is the ordered pairs.
Well we can do this using substitution since that might be easier
So since y = 2 - 0.5x we can substitute it into x - 2y = 8
That gets us:
x - 2(2 - 0.5x) = 8
Next distribute the -2:
x -4 + x = 8
Combine like terms and solve for x!
2x = 12
x = 6
Now substitute x into any of our y = 2 - 0.5x so we get
y = 2 - 0.5(6)
y = -1
So our answer is (6,-1)
Answer:
A= 2.50x+82.50x+8
B= 0.50x+240.50x+24
