Solve 3x + 11 = k for x.
masya89 [10]

3x +11 = K

To solve for X, we need to isolate x on one side.

Subtract 11 from both sides:

3x = K -11

Divide both sides by 3:

x = (k-11)/3

These cylinders are similar. Find the volume of
Basile [38]

Answer:

V_s=85\ cm^3

Step-by-step explanation:

Let V_s\ and\ V_b be the volumes of the smaller and bigger cylinder.

The formula for the volume of a cylinder is given by :

V=\pi r^2 h

As the two triangles are similar, the cube of their ratio would equal the ratio of their volume i.e.

\dfrac{V_s}{V_b}=(\dfrac{h_s}{h_b})^3\\\\\dfrac{V_s}{V_b}=(\dfrac{3}{5})^3\\\\\dfrac{V_s}{V_b}=0.216\\\\V_s=393\times 0.216\\\\V_s=84.8\\\\or\\\\V=85\ cm^3

So, the volume of the smaller cylinder is equal to 85\ cm^3.

Item 11 Identify the independent and dependent variables. The equation c=0.09s gives the amount c (in dollars) of commission a s
diamong [38]

Answer:

C is dependent variable

S is independent variable

Step-by-step explanation:

Here, give the equation, we are told to identify the independent and the dependent variable

When we talk of the independent variable, it is that variable which values does not depend on whatever values the second variable in the equation has. It is that variable that is used to find the other variable in the equation

While the dependent variable depends on the values we input in the equation. It is the variable that we arrive at after plugging different values for the independent variable

now looking at the question, the equation we have is as follows;

c = 0.09s

To get the value of c which is the cost , we have to input different values of a. As is the amount in sales that we have that will yield the value of the commission to be received

Thus, we can categorically say that the values of the commission are dependent on the values we get from the sales

Hence, while commission represents the dependent variable, the values of the sales are the independent variables
