Two variables vary inversely if their product is constant (does not change). The variables w and t vary inversely so their product wt = k were k is a constant. Solving this for t we get t=k/w
We are told that w = 4 and t = 1/5 so we know their product wt = (4)(1/5) = 4/5. This is what I called k before.
Therefore the relationship between w and t can be modeled by t = (4/5) / w. That is, t = 4 / 5w
Further, when w = 9, we find t by substituting 9 for w in the equation just found and obtain: t = 4 / [(5)(9)] = 4/45. That is, when w = 9, t = 4/45.
This mean choice D is the correct answer.

Answer:
625000
Step-by-step explanation:
x+12%= 700000
x*1.12=700000
x=700000/1.12
x=625000
Answer: 10^2
Step-by-step explanation:
43.27×9.1=
393.757
Estimate. 400
10×10=100×10=1000
This is wrong because the estimated number is oy 400.
So, 10×10=100
The answer is 10^2.
