Which formula shows a joint variation?
djyliett [7]

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:

y=kxz

Where x,y and z are the variables and k is the constant of proportionality.

As you can see, y is directly proportional to x and z.

2. Keeping the information above, you have:

I) V=lwh (V varies jointly with l, w and h.

II) V=\frac{1}{3}r^{2}h\pi (If \frac{\pi}{3} is the constant of proportionality, V varies jointly with r^{2} and h).

III) V=Bh (V varies jointly with B and h.

Help please I need to find the area I don’t know how thanks
otez555 [7]

Answer:

49.62

Step-by-step explanation:

You can start by dividing the shape into 2 separate rectangles to make calculating the area easier.

9.3 x 2.4 = 22.32

10.5 x 2.6 = 27.3

Then, add the areas of the two separate rectangles to find the total area of the shape.

22.32 + 27.3 = 49.62. Hope that helped
