Answer:
16.2
Step-by-step explanation:
multiply 12.2 by 8.5 by 2 and 15.4 by 8.5 by 2 then add them together to get 207.4 plus 4035.6 which is 4513 then divide 4513 by 287.5 to get your answer
To compare their speed (rate), we need to have the same time or same distance to use as a reference.
Matt ran 50 meters per 10 seconds. Molly ran 30 meters per 5 seconds. If she ran for 5 more seconds, she would have gone 30 more meters, for 30 meters per 10 seconds. Thus, Molly went faster.
Alternately, you could calculate their speeds in meters per (one) second and compare. 50 meters per 10 seconds is 5 meters per second, and 30 meters per 5 seconds is 6 meters per second.
Answer:
F because you cannot prove that any of the angles are the same with only one set of parallel lines
