Answer:
DC = 3
Step-by-step explanation:
Based on triangle similarity theorem, we would have the following equation:
Plug in the values
Cross multiply
3(9 + DC) = 9×4
27 + 3DC = 36
Subtract 27 from each side
3DC = 36 - 27
3DC = 9
Divide both sides by 3
DC = 9/3
DC = 3
Step-by-step explanation:
Average = 30 mil/h
Period = 10s
Av = 30 ÷ 360 / 3600 ÷ 360
Av = 1/12 mil / 10 sec
Answer:
101 i think.
Step-by-step explanation:
My logic is:
make an initial group of 20, this will be G1. That is one group. Then, swap one of the remaining 5 for one of the 20. That makes 20 more groups for each person. 5*20=100, plus the first group, G1, makes 101 groups.
