6-4 because the equation for slope is m=y2-y1/x2-x1
Answer: the weight of each bags are 1.85kg,
1.85kg and 3.05 kg
Step-by-step explanation:
Total weight of the three bags is
6 3/4 kg. Converting to decimal, it becomes 6.75
kg.
Two of them have the same weight. Let X
represent the bags of equal weight. Their total
weight would be 2x. The third bag is heavier
than each of the bags of equal weight by 1 1/5
kg. Converting to decimal, it becomes 1.2kg. It
means that the weight of the third bag would be
x + 1.2
Therefore, for the three bags,
2x + × + 1.2 = 6.75
3x = 6.75 - 1.2 = 5.55
x=5.55/3=1.85
Weight of the third bag is
1.85+1.2=3.05kg
Answer:
5. 200/1 = 200 ft/min
6. 600/3 = 200 ft/min
Step-by-step explanation:
5. The rate of change of a graph is the ratio of vertical change to horizontal change. You are asked to find the rate of change from 1 minute to 2 minutes, so you want to find the distance (ft) at 2 minutes and at 1 minute.
Reading the graph, you see that at 2 minutes, the distance is 400 ft. At 1 minute, it is 200 ft.
So, the ratio of the two differences is ...
change in distance / change in time
__
6. Using the same idea, we want to use the graph values at 4 minutes and 1 minute.
