Peter charges $5 an hour for

Mathematics
1 answer:
Sphinxa [80]3 years ago
6 0

Answer:

21 more hours

Step-by-step explanation:

Divide $75 by $5 to know how many hours he worked for. 75/5 is 15. So he worked for 15 hours so far.

Then find out how many hours will make $180. 180/5 = 36 hours. He needs to work 36 hours to earn $180 but he already worked 15. So, find the amount left. 36 - 15 is 21 hours.

Determine the nth term rule and find the 45th term for the arithmetic sequence with a10=1 and d-6
kari74 [83]

Answer: -209

Step-by-step explanation:

Formula for arithmetic progression

= a + (n - 1)d

Since a10 = 1 and d = -6

a10 = a + 9d

a + 9(-6) = 1

a - 54 = 1

a = 1 + 54

a = 55

Therefore, 45th term = a + (n - 1)d

= a + (45 - 1)d

= a + 44d

= 55 + 44(-6)

= 55 - 264

= -209
