What percentage of the total students chose skateboarding?
Sergeu [11.5K]
I FOUND YOUR COMPLETE QUESTION IN OTHER SOURCES.
 PLEASE SEE ATTACHED IMAGES.

 For this case, the first thing we are going to do is add the number of students in each of the disciplines.
 We have then:
 walk = 9
 bike = 8
 skateboard = 3
 Total: 20
 The percentage sought is then:
 (3/20) * (100) = 15%
 Answer:
 
percentage of the total students chose skateboarding is:
 
D.) none of these

4. An airplane at T(80,20) needs to fly to both U(20,60) and V(110,85). What is the shortest possible distance for the trip?
damaskus [11]
The distance formula for two points in a plane is 
D=sqrt( (x1-x2)^2 + (y1-y2)^2 ) 
 From T to U
 D= sqrt((80-20)^2 + (20-60)^2) = 72.11 
 Then flying from U to V
 D= sqrt((20-110)^2 + (60-85)^2) = 93.4 
 So T to U to V = 72.11+93.4 = 165.5 
 BUT checking also T to V to U
 From T to V
 D= sqrt((80-110)^2 + (20-85)^2) = 71.6
 Then from V to U
 D= sqrt((110-20)^2 + (85-60)^2) = 93.4 
 So from T to V to U = 165
 Pretty much the same both directions
 So yes the answer is A
