School a has 216 students and 12 classrooms. school b has 104 students and 4 classrooms. how many students would have to transfer from school b to school a for the ratio of students to classrooms at both schools to be the same?

4 students will transfer from School B to School A.

Step-by-step explanation:

School A has 216 students and 12 classrooms.

Or students per classroom

School B has 104 students and 4 classrooms.

Or students per classroom

Now, the average will  be :

=> students per classroom

As school B has more than the average students, we will transfer students to A, that makes 22 students per classroom.

Therefore, there are 4 students who will transfer from School B to School A for the ratios of students to classrooms at both schools to be the same, which is 22 students: 1 classroom.

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
