Answer:
day 1 total $60+$15=$75
day 2 total $95+$12=$107
total 2 days = $181
Step-by-step explanation:
Answer:
Total cost for two days for the n members of the club = 155 + 27 n
Step-by-step explanation:
Total number of persons = n
The first day the members paid $60 for transportation plus $15 per ticket to the planetarium.
Day 1 cost = 60 + 15 x n = 60 + 15 n
The second day they paid $95 for transportation plus $12 per ticket to the geology museum.
Day 2 cost = 95 + 12 x n = 95 + 12 n
Total cost = Day 1 cost + Day 2 cost
Total cost = 60 + 15 n + 95 + 12 n = 155 + 27 n
Total cost for two days for the n members of the club = 155 + 27 n
Answer:
169 seconds
3rd lap
0.923 minutes
Step-by-step explanation:
To solve this question, we would use formula for arithmetic progression in solving it.
S(n) = a + (n - 1)d
If a = 25 s
n = 10
d = 16
S(n) = 25 + (10 - 1)16
S(n) = 25 + 9 * 16
S(n) = 25 + 144
S(n) = 169
It takes him 169 seconds to cycle his tenth lap
b
If S(n) = 55.4, what is n
55.4 = 25 + (n - 1)16
55.4 - 25 = (n - 1)16
30.4 = (n - 1)16
n - 1 = 30.4/16
n - 1 = 1.9
n = 1.9 + 1
n = 2.9 approximately 3
Therefore, he's on his 3rd lap
c
Total time cycled is dependent on the total cycles he made, and going to question 2, we were told he made 55.4 seconds of cycle
55.4/60 = 0.923 minutes
The formula is pi r squared so
10 is the diameter and you need the radius so divide the diameter in half to get 5 then plug it into the equation so the equation should be pi 5 squared
Then you square 5 to get 25 so now you have
3.14(for pi) x 25
And the answer is 8.746913126...
And the final answer is about
8.7 meters squared
I hope I could help
