Answer:
Step-by-step explanation:
If two variables, x and y have a direct variation, it means that an increase in x would lead to a corresponding increase in y. A decrease on x would lead to a corresponding decrease in y.
Therefore, we would compare the scenarios to determine which is not a direct variation. The correct option is
d) Time taken will be less if number of workers are increased to complete the same work.
The rest are direct variation scenarios
Answer:
C
Step-by-step explanation:
There is a common ratio between consecutive terms
r = 24 ÷ 16 = 36 ÷ 24 = 54 ÷ 36 = 1.5 = 
This indicates the sequence is geometric with nth term ( explicit formula )
f(n) = a₁
where a₁ is the first term and r the common ratio
Here a₁ = 16 and r = , then
f(n) = 16 
→ C
Answer:
9x = 16
Step-by-step explanation:
2+2/3x=3/4
4/3x = 3/4
3x/4 = 4/3
9x = 16
Answer:
T = n + 132
Step-by-step explanation:
Initially you have n dollars in your bank account.
Since the question doesn't ask or concern the future or present value of money, after depositing $132 you will totally (T) have:
T = n + 132
