process to two main categories depend on two variables ( product standardization ‚ and product volume). First category is intermittent operations which is the process that used to produce a variety of products with different processing requirements in lower volumes. And the second category is Repetitive operations which is the process that used to produce one or a few standardized products in high volume. Grouping process into two main categories of operations is useful to understanding of their

density of clay from the linearized plot of mass and the diameter cubed (m‚ D^3) data. Yielding a slope of 1.093 +/- 0.01749 m^3/g. Since the density of an object is ρ=mV And the formula for the volume of a sphere is V=π6D3 The density of a material shaped into a sphere would be equal to the volume of a sphere plugged into the density equation‚ which is: ρ=mπ6D3 Solved for D3: D3= 6πρm In the linear plot‚ it is expectable to say the slope=6πρ Using the value of slope‚ density can be solved

Write an expression to represent the total volume of two different sized boxes as a sum of cubes if one of the boxes has sides with a length of 1 foot and the other has sides with a length of x feet. (1^3 + x^3) = (1 + 3)(1^2 - 1x + x^2) = 0 b. Factor the sum of cubes. (a^3 + b^3 = (a + b) (a^2 - ab = b^2) c. Calculate the total volume of the two boxes if x = 3 feet.

calculate this density‚ we first found the mass of the container that was to be holding the substances. We then found the volume of the substance‚ and lastly determined the mass of the container and substance. We subtracted (Container + Substance) – Container to find the mass of simply the substance. In order to distinguish density‚ we took the final mass divided by the volume‚ and identified the substances based on Density Charts we found online. Originally we hypothesized that we would be able

The purpose of this experiment is to calculate the thickness of aluminum foil in centimeters. In this lab we measured the thickness by plugging in the quantitative properties of our piece of aluminum foil into the equation for volume and then isolated “h” to solve for height. The thinking behind this method is that by using accurate measurements and proper significant digits we can calculate and accurate thickness. Materials: Electronic Scale

Density of Metals Problem: How does the mass and volume help determine the density of known metal samples? Hypothesis: When comparing the density of Zn(zinc) and Cu(copper)‚ you will find that Copper is more dense than Zinc. You can test this out by using the density formula D=m/v. Materials: * 2 metals (options: zn‚ al‚ or cu) * 3 samples of each metal (small‚ medium‚ and large) * Scale/Balance * Calculator * Water * Graduated Cylinder Safety: * Be prepared for your
