Twelve of the students in the school choir like to sing solos. These 12 students make up 24% of the choir. How many students are in the choir? A.100
B.50 students
C.12.5
D.24

50 Students

Step-by-step explanation:

24% = 0.24

12/total amount of students = 0.24

12/0.24 = total amount of students

total amount of students = 50

i'm not sure i quite understand, could you provide more information?

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
