Answer:
the answer is C, 369
Step-by-step explanation:
1. divide 800 by 40 which will give you 20
2. then multiply 18 by 20
3. answer is 360
the reason I did this was because if you had multiplied math, physics and chemistry by 20 it would have given you the total of 800 trials
48-126=-78
-78/126= -0.<span>619047619
-0.</span>619047619x100=<span>61.9047619%
This can be rounded to 62%
Hope this helps :)</span>
Answer:
208.........not sure but this can be the ans
We are given
arithmetic sequence: u(1)= 124, u(2)= 117, u(3)= 110, u(4)=103
so, first term is 124
u(1)= 124
now, we can find common difference



now, we can find kth term

now, we can plug values
and we get



u(k) must be negative
so,


now, we can solve for k


so, it's closest integer value is
