1, both functions are linear
Step-by-step explanation:
I think we cannot find the sum because it will continue on so the series is multiply by 4
4/9 (4 out of 9) because you add them all together then count the number of blue marbles then since you put back the first marble, the dominator is still the same
They are congruent:)<span />
You know that 1 km=1000 m, then the length of the road
km is
metres.
A group of 8 people are picking up litter along the road and each person is assigned an equal section of the road. The whole road has length 800 m, then for each person will be assigned 800:8=100 m of the road.
If you want to know the length of each part in km, then 1 m=0.001 km and 100 m =1 m·100=0.001 km ·100=0.1 km.
