The answer is the first option: I, II and III.
The explanation is shown below:
1. By definition, there is a joint variation when a variable depends on two or more different variables. Therefore, you can express it as following:
Where and are the variables and is the constant of proportionality.
As you can see, is directly proportional to and .
2. Keeping the information above, you have:
I) ( varies jointly with , and .
II) (If is the constant of proportionality, varies jointly with and ).
III) ( varies jointly with and .
Answer : I, II and III
To find volume formula that shows joint variation we analyze each option
Joint variation always depends on atleast two dependent variables
for example y = kxy
The variable y depends on x and y and k is constant of proportionality
V= lwh
It means volume depends on length , width and height. 1 is the constant of proportionality .
V depends on radius r and height h. Here 1/3 pi is the constant of proportionality
V= BH
V depend on base b and height h . 1 is the constant of proportionality .
So answer is I, II , III

Answer:
-10
Step-by-step explanation:
combine like terms -5x+9=59 subtract 9 from both side and get -5x=50 so x=-10

Let m represent the marked price. After the discount, the price is 0.80m. After the tax is added, the price is (0.80m)(1.13). This value is Rs 904, so the marked price is ...
(0.80m)(1.3) = ₹904
m = ₹904/(0.80×1.13) = ₹904/0.904
m ≈ ₹1000
The marked price of the watch is ₹1000.
