The ratio of students with blond hair to students with brown or
black hair is 1:2. If there are
212 students with brown or black
hair, how many students have
blond hair?

106

Step-by-step explanation:

212/2 is 106 so there is 106 blonde students.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
