Answer:
3 scarves
Step-by-step explanation:
The answer is 170 minutes or 68/24 hours so, common denominator is 1/24 hours.
1) 1+3/4+2/3+1/4+1/6=(24+18+16+6+4)/24 so it is 68/24 and times 60 it will be 170.
Answer:
C
Step-by-step explanation:
The formula to find any term of an an arithmetic sequence is given by
=
=(n-1)d,
where we have first term
=8,
and d which is the common difference , and n is the term we need to find (in our case is 20)
the difference d=3, as you see each number is the previous minus 3
for S20=8+(20-1)*(-3)=8+(19)*(-3)=8-57=-49
S20=-49, this the 20th term
Answer:
Step-by-step explanation:
We are given,
.
It is required to find the value of y.
Now, on simplifying above equation, we get,
i.e.
i.e.
i.e.
Hence, the missing term is .
