we know that having similar triangles so the ratio of sides,area and volume are same.

we know that
will be the area of triangle.

so 
so the ratio of the perimeter of two triangles will be

ratio of the perimeter=
Yes they do. Notice that for each step in x there a +4 in y. If you want an equation we can set it up with the inforation given

Yes theres a relationship because for every meter she runs it takes her 4 minutes for each.

3 + |t + 4| < 10
Subtract 3
|t + 4| < 7
Because it is absolute value...
t + 4 < 7 AND t + 4 > -7
t < 3 AND t > -11
ANSWER:
t < 3 AND t > -11
