I think the answer would be 8+9
Average speed = (total distance covered) / (time to cover the whole distance)
Total distance = (516 + 368) = 884 yards
Total time = (6 + 4) = 10 minutes
Average speed = (884 yards) / (10 minutes)
Average speed = 88.4 yards/minute (C)
Other ways to write the same speed:
-- 4.42 feet/second
-- 265.2 feet/minute
-- 53.04 inches/second
-- 5,304 yards/hour
-- 3.014 mph (rounded)
-- 810.07 furlong/fortnight
Answer:
Opposite sides must be congruent.
Step-by-step explanation:
Given is a picture of a quadrilateal ABCD
We have to prove that this is a parallelogram.
Recall the properties of parallelogram as
i) diagonals bisect each other
ii) opposite sides parallel
iii) opposite sides congruent
or iv) one pair of opposite sides equal and parallel
We have hence to get opposite sides congruent
So last option is right
The domain is (-5,4). If that makes any sense, if it doesnt ill explain
