There are 2 x intercepts, x=-4 and x=-1
Answer:
The answer to your questions is: 25 new teachers
Step-by-step explanation:
Data
# of students = 2000
ratio = 3:80 teachers to students
New teachers = ?
Process
I suggest to use rule of three to solve this problem
3 teachers ---------------- 80 students
x ---------------- 2000 students
x = (2000 x 3) / 80 = 75 teachers
Number of initial teachers = 75
The ratio change to 1:20
1 teacher ------------------- 20 students
x ------------------- 2000 students
x = (2000 x 1) / 20
x = 100 teachers
Number of new teachers = 100 - 75 = 25
Answer:
7
Step-by-step explanation:
10 x 2 = 20
10 - 3 = 6
Volume of cylinder= pi x (radius)2 x height
= 3.14 x (2)2 x 5
=62.8 cubic cm
Its same i think
100-40=60
130-70=60
