Answer:
a) 18 students per teacher
b) 9 students per tutor
c) 7 tutors
Step-by-step explanation:
An arts academy requires there to be 6 teachers for every 108 students and 5 tutors for every 45 students.
a) How many students does the academy have per teacher?
6 teachers = 108 students
1 teacher = x
Cross Multiply.
6x = 108
x = 108/6
x = 18 students per teacher
b) Per tutor?
5 tutor = 45 students
1 tutor = x
Cross Multiply
5x = 45
x = 45/5
x = 9 students
= 9 students per tutor
c) How many tutors does the academy need if it has 63 students?
45 students = 5 tutors
63 students = x
Cross Multiply
45x = 63 × 5
x = 63 × 5/45
x = 7 tutors
Answer:
is equation of BC
Step-by-step explanation:
Given that AB and BC form a right angled triangle at point B.
i.e. BC is perpendicular to AB
Line AB contains two points (-3,-1) and (4,4)
Slope of AB =
Slope of BC would be -1/slope of AB since AB and BC are perpendicular
Slope of BC =\frac{-7}{5}
Also we got a point on BC as B.
Use point slope formula

So the correct answer is the 1st answer
hope this helps you
Can I have the brainliest please?
If you only have two of the six measures of a triangle, you cannot find the others. You need at least 3 measures, including at least one side, in order to solve a triangle.
You can always use the Law of Cosines (if you have sufficient information), or the Law of Sines (if you have sufficient information).
