Answer:
1240 (I'm not so sure but per my calculation that is what i got)
Step-by-step explanation:
Boy : Girl
11 : 9
124 + x : x
11/9 = 124 + x / x
9(124 + x) = 11 x
1116 + 9x = 11x
1116 = 11x - 9x
1116 = 2x
x = 558
Thus, there are 558 girls in the school
Number of boys = 124 + x
= 124 + 558
= 682
Therefore, total number of students = 558 + 682 = 1240 students
First we need to arrange the numbers in this number set from smallest to biggest:17,18,24,27,31,39,42,47,55,65. Then there are 10 numbers in this number set. So when we calculate the median, we need to find the middle two numbers and calculate their average. So the median is (31+39)/2=35. SO the answer is B

Answer:
13.5 minutes
Step-by-step explanation:
Cross multiply
3 × 576 = 128x

1,728 ÷ 128 = x
13.5 = x
5 and 1 you multiple 5*1 to get 5 and add 5+1 to get 6
