From the problem statement, we can come up with the following equations:
Plugging in for each equation, we can get the answer:
From this, we can see that the value is equal for both stores.
Answer:
d = 10/72
Step-by-step explanation:
c and d vary inversely
c = k/d
Where,
k = constant of proportionality
d = 2/9 when c = 5
c = k/d
5 = k ÷ 2/9
5 = k × 9/2
5 = 9k/2
Cross product
5*2 = 9k
10 = 9k
k = 10/9
c = k/d
c = 10/9 ÷ d
c = 10/9 × 1/d
c = 10/9d
find d when c = 8
c = 10/9d
8 = 10/9d
Cross product
8*9d = 10
72d = 10
d = 10/72
100 meters is -1°C
1,000 meters is -10°C
10,000 meters is -100°C
And 2,000 meters is -20°C
12Km is 12,000 meters
12,000 meters is -120°C
Your answer is -120°C
