Choice b and c are right I think
The coordinates of the midpoint are the average of the coordinates of the given points.
So, the x coordinate of the midpoint is the average of the x coordinates of the given point:
And similarly, the y coordinate of the midpoint is the average of the y coordinates of the given point:
So, the midpoint is the point 
Answer: 30 feet per second
========================================
x = diameter, y = speed of water
y varies inversely with respect to x, so, y = k/x for some constant k
If x = 0.6 and y = 5 pair up, then y = k/x turns into 5 = k/0.6 which solves to k = 3 when you multiply both sides by 0.6
So the equation y = k/x turns into y = 3/x
Now plug in the diameter x = 0.1 to find the speed to be...
y = 3/x
y = 3/0.1
y = 30 feet per second
Answer:
Step-by-step explanation:
By the marks on the angles of this triangle, it is isosceles. By the Isosceles Triangle Theorem, if 2 angles of a triangle have the exact same measure, then the sides across from those angles have the exact same measure as well. That means that, algebraically,
5x - 2 = 33 and
5x = 35 so
x = 7
