Which geometric instrument would i use to measure the length of a segment, the compass or the straightedge? explain your answer.

straigthedge.

Explanation:

1) The straightedge is a geometric instrument with straight edge used to draw lines. When the straightedge has equally spaced marks or divisions, like mm, cm, inches, it is a ruler and can be used to meaure the lengths of straight figures, like segments.

2) On the other hand, a compass is a geometric tool or instrument used to draw circles or arcs; it does not have lenth's marks or divisions to measure straight figures.

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

answer: the answer is 100 x 12,500, which is 1,250,000.

step-by-step explanation: emily solved for a part when she should have solved for the whole.  

875,000 should be the numerator of the equivalent ratio.  

70 x 12,500 is 875,000.
