Answer:
(E) 45
Step-by-step explanation:
From the question, s and t are positive integers.
s = 64.12t
From the division of s/t which gives 64.12, 0.12 it the remainder.
Now, split 64.12 into its integral multiple.
s = (64 + 0.12)t
s = 64t + 0.12t
The value that could be the remainder would be any of the values given in the options that will give positive integer when it equals 0.12t.
Let's test for the answer
(A) 0.12t = 2
t = 16.77 Not an integer
(B) 0.12t = 4
t = 33.33 Not an integer
(C) 0.12t = 8
t = 66.67 Not an integer
(D) 0.12t = 20
t = 166.67 Not an integer
(B) 0.12t = 45
t = 375 An Integer (CORRECT ANSWER)
Answer:
a₅ = 37
Step-by-step explanation:
The term to term rule ' subtract 3 ' is the common difference d of an arithmetic sequence with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₁₂ = 16, then
a₁ + 11d = 16 ← substitute d = - 3
a₁ + 11(- 3) = 16
a₁ - 33 = 16 ( add 33 to both sides )
a₁ = 49 , then
a₅ = 49 + (4 × - 3) = 49 - 12 = 37
