a) together, they all drink about 2,090 glasses of water in one day. (418 * 5 = 2,090).
b) 2,090 * 7 (7 days in 1 week) = They drink about 14,630 glasses of water in one week.
c) 14,630 * 4 (4 weeks in 1 month) = About 58,520 glasses of water in one month.
d) 1,000,000/58,520 ≈ 17. It would take all of the students about 17 months to drink 1,000,000 glasses of water.
Hope that helps!
Answer:
n = 3
Step-by-step explanation:
This is a ratio.
12 km : 3 h
simplify to-
4km : 1 h
which means the hiker traveled 4 km per 1 hour.
The 1st, 4th, and 7th terms make an arithmetic sequence of their own. The 4th term is the average of the 1st and 7th, so ...
(1st +7th)/2 = 4th
1st + 7th = 2×4th
1st = 2×4th - 7th
The first term is ...
2*141 - 132 = 150
