Because 34.4567 is closer to 34.46 than to 34.45, so the answer is 34.46.
Answer:
270
Step-by-step explanation:
For any arithmetic sequence
nth term is given by
nth term = a + (n-1)d
where a is first term,
d is common difference
d is given by nth term - (n-1)th term
sum of n terms given by
sum = n/2(2a + (n-1)d)
________________________________________________
Given arithmetic sequence
-2,0,2,4,6,8...
first term a = -2
lets take third term as nth term and second term as (n-1)th term to find common difference d.
d = 2 - 0 = 2
using a = -2 , d = 2, n = 18
thus, sum of first 18 terms = n/2(2a + (n-1)d)
=18/2( 2*(-2) + (18-1) 2)
=9 ( -4 + 34)
=9 ( 30) = 270
Thus, sum of first 18 terms is 270.
(1 month) 125+45=170
(2 month) 170+45=215
(3 month) 215+45= 260
(4 month) 260+45=305
(5 month) 305+45=350
(6 month) 350+45=395
Li needs at least $360 in get account which means 5 months would not work because it is less than $360.
So, add one more $45 and get $395 which is more than enough money for Li.
Overall, Li would need 6 months to get at least $360 in her bank account.
I hope this helps!!
Please make brainliest to help me!!
Thanks!!
The answer to this question is 2. You use PEMDAS. 6 + 2 is 8 and 16 divided by 8 is 2
