Answer:

Step-by-step explanation:
Slope of the line segment = [(-8)-(-2)]/[(-9)-3]=-6/-12=1/2
Slope of the perpendicular bisector x slope of line segment = -1
Slope of perpendicular bisector = -2
Mid-point of line segment = ((-9+3)/2, (-8+(-2))/2) = (-3, -5)
The perpendicular bisector passes through the mid-point.
By point-slope form,

0.4L = 400ml
Each student effectively adds 10ml of water so 22 students are adding 10ml of water each. Therefore, 22 x 10 = 220ml total in all the containers added by all 22 students
Water left = 400 - 220 = 180
The answer is B.
Count how much spaces from one point on the end of the line to the other.
Line VU has 9 units
Line VW has 12 units
Line UW has:
a² + b² = c²
9² + 12² = c²
81 + 144 = c²
c² = 225
√c² = √225
c = 15
Line UW has: 15 units
Now add all the units together to get the perimeter:
9 + 12 + 15 =
21 + 15 =
36
36 is your answer
