Answer: 45,000.
Step-by-step explanation:
The equation of inverse variation is given by:-
, where k is the constant of proportionality.
Given: After owning the car for 3 years, its value is $15,000. After owning the car for 5 years, its value is $9,000.
Here,
Then,
or [answer is same in both cases.]
Hence, the constant of proportionality in this inverse variation is 45,000.
Answer: 3/4 of an hour left.
Step-by-step explanation:
Step 1: 2 hours = 4/4 +4/4
Step 2: 4/4 - 2/4 = 2/4
Step 3: 4/4 - 3/4 = 1/4
Step 4: 2/4 + 1/4= 3/4

It’s the way you make it look dummy
Answer:
- A: 700
- B: he put the decimal point in the wrong place
Step-by-step explanation:
Part A: The problem 49/0.07 can be rewritten as 4900/7 by multiplying numerator and denominator by 100. Then it is more clear that the correct answer is (49/7)×100 = 700.
___
Part B: I've always had trouble reading Marco's mind, so I cannot tell you what mistake he made. I can tell you the decimal point in his result is in the wrong place.
