Answer:
Net_change_in_depth = 450/7 ft = 64 2/7 ft
Step-by-step explanation:
Missing info attached below
Depth_of_the_frequency_signal = -180 4/7 ft = -1264/7 ft
Depth_of_the_submarine = -116 2/7 ft = -814/7 ft
Net_change_in_depth =
Depth_of_the_submarine - Depth_of_the_frequency_signal
Net_change_in_depth = -814/7 ft - (-1264/7 ft)
Net_change_in_depth = 450/7 ft = 64 2/7 ft
Answer
42
Explanation
Let’s say:
Set of envelopes: {a,b,c,d,e,f,g}
Set of postage stamps: {1,2,3,4,5,6}
For an envelope you can have:
1a 2a 3a 4a 5a 6a (6 different combinations)
This applies to all 7 different types of envelopes.
Therefore 7 • 6 = 42
