88% = 88/100 = 22/25
22/25 x 350 = 7700/25 = 308
Therefore 308 students voted
Answer:
Step-by-step explanation:
P1 = (3.5,5) in the form (x1,y1)
P2 = (3.5,-12) in the form (x2,y2)
dist = sqrt[ (x2 - x1)^2 + (y2-y1)^2 ]
dist = sqrt[ (3.5-3.5)^2 + (-12-5)^2 ]
dist = sqrt [ 0 -17^2]
dist = 17
The speed of the water in the 3 feet radius is 25 feet per second.
