Answer:
6 hours
Step-by-step explanation:
Set up a proportion:
15kg/5 hrs = 18kg/x hrs
Cross multiply:
5(18)=15x
90 = 15x
Divide by 15:
90/15 = x
6 = x

B. 7/3
C. 10
D. 21
Answer:
D. 21
Step-by-step explanation:
The equation tells you xy = k. Substituting the given values, you get ...
7·3 = k
21 = k
Answer:
D) 21
Step-by-step explanation:
The given inverse variation equation is x.y = k, where k is the constant of proportionality.
Given: x = 7 and y = 3.
We need to find the constant variation, k.
To find the constant variation, k, plug in x = 7 and y = 3 in the given equation and simplify.
k = 7*3
k = 21.
Therefore, the constant of variation k = 21.
Answer is D) 21.
