Answer:
2.5
Step-by-step explanation:
The formula to find the midpoint of a line segment: 
<u><em>Where:</em></u>

1) Substitute the values into the midpoint formula.

2) Solve it.
= 
= (2.5, 8.5)
Answer:
15mph
Step-by-step explanation:
So to figure this out you have to get the total unit rate by dividing 30 and 2 which in total gives you 15
So congratulations you can ride 15 miles per hour :)
The 3 values would be 9 , 10 and 11.
because:
48<6(9)
48<54
48<6(10)
48<60
48<6(11)
48<66
For the first one: A=pi*r^2*1/8 (1/8 becuase we are finding the area of one pane)
A=pi*16/8
A=2pi
For the second one: First do the larger circle minus the smaller circle (pretend they are whole circles)
A(larger)=pi*18^2
=324pi
A(smaller)=pi*8^2
=64pi
A=324pi-64pi =260pi
Now, a whole circle is 360 degrees so 150 degrees is 5/12 of a circle. We take 5/12 of 260pi to get the answer
260pi*5/12=340.3
