Lots of points:school A has 480 students and 16 classrooms. school B has 192 students and 12 classrooms.
how many students would have to transfer for the ratio of students to classrooms were the same?
thanks
Answers
16 + 12 = 28 classrooms total
672/28 = 24 students per room
24 * 12 = 288 students that need to be in school B
288 - 192 = 96 students who have to transfer

Week 1 : - 40
Week 2 : - 56
Week 3 : 105
Week 4 : 70
Week 5 : 140
Week 6 : ?
At the end of the 6th week, net profit is 252.
Profit = 105 + 70 + 140 = 315
Loss = 40 + 56 = 96
Net Profit = 315 - 96 = 219
252 - 219 = 33 Profit on Week 6.
Average profit : 252 / 6 = 42 per week

Answer:
x = 127
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 6, thus
sum = 180° × 4 = 720°
Sum the interior angles and equate to 720 for x
120 + 100 + 128 + 133 + 112 + x = 720, that is
593 + x = 720 ( subtract 593 from both sides )
x = 127
