18 ? am not really sure tho its kinda difficult lol
6/10 of an inch= 0.6
7 (times) 0.6 (equals) 4.2
Total no. of students - 140 students
Total no. of students from all schools= 140+70+35+105=350
school A= 140÷350×100=40./. (multiplying by 100 because it's the total percentage )
School B = 70÷350×100=20./.
School C = 105÷350×100=30./.
School D = 105÷350×100= 10./.
Consisting all the schools percentage it gives 100./.
Hope this helps
The area would 30 in^2
Reason:
Area of a triangle =1/2 bh
Area= 1/2 (12)(5)
Area =(6)(5) (because a half times 12 =6)
Therefore Area =30 in^2
Hopefully that helps, if not I apologize
