Answer:
51m
Step-by-step explanation:
-Paul is 6ft, and has a 10ft shadow. The pole has a 85ft shadow:
-Using ratios:
Let h be the height of the flagpole:
Hence, the height of the pole is 51m
Suppose interstate highways join the six towns A, B, C, D,E,F as follows: 1-77 goes from B through A to 1-82 goes from C through
D then through B to F: 1-85 goes from D through A to F; 1-90 goes from C through E to F and 1-91 goes from D to E.
a) Draw a graph of the network with vertices for towns and edges for segments of interstates linking neighboring towns. b) What is the minimum number of edges whose removal prevents travel between some pair of towns?
c) Is it possible to take a trip starting from town C that goes to every town without using any interstate highway for more than one edge (the trip need not return to C?
