Answer:

Step-by-step explanation:

The formula for determining the volume of a sphere is given as

Volume = (4/3) πr³

where r is the radius and π is a constant whose value is 3.14

From the information given,

Diameter = 9.4 mm

Radius = diameter/2 = 9.4/2

= 4.7 mm

Volume of sphere = 4/3 × 3.14 × 4.7³

= 434.67 mm³

The formula for determining density is expressed as mass/volume

Mass = 3.475 g

Density = 3.475/434.67 = 0.008g/mm³

M+5n=p for m <br> Solving for a variable
Verdich [7]

Answer:

M=p-5n

Step-by-step explanation:

Here we are given that M+5n=p

We are asked to solve this equation for M. In order to do that we will follow these steps.

Subtracting 5n from both sides we get

M+5n-5n=p-5n

M=p-5n

Hence , now we have our M as dependent variable,  whose value depends on the values of p and n. One or both  of them can be independent variable/.
