The minimum value of cosθ is -1
-1 + d = -5
d = -4
lets say there are 100 girls.
4/5 of 100 is 80, so 80 girls have brown hair.
3/4 of the 80 who have brown hair have long hair.
3/4 of 80 is 60.
so we know that out of 100, 60 have long brown hair.
in simplest fraction form, 60/100= 3/5
Just multiply them together and you'll get 58,466.
The distance between -10 and 9 is 19 and the distance between 2 and -7 is 9
Hope this helps
