It should be B. The dash-line triangle is half the size of the solid-lined triangle. You can find the scale factor by finding the ratio between the side lengths of the two triangles. The scale factor in this case is 2 because you are reducing thr solid-lined triangle by one half. If you are reducing by a fraction, it means that you are enlarging be the reciprical of the fraction. As reducing implies division and dividing a fraction is equivalent to multiplying by the reciprical. Thus the correct answer is B.
The equivalent ratio is 1:4<span />
Answer:
the fourth one does
Step-by-step explanation:
The only graph that shows a proportional relationship is the line that crosses the origin point (0,0). The other graphs are linear functions but not not proportional relationships. The general form of a proportional relationship is y = kx, where k is the proportionality constant.
A because you would have to multiply 5x2x8x10
