C . Drivers :) have a great day
Answer: d. increased material cost per unit
Explanation:
Direct materials quantity variance has to do with the difference between the budgeted <em>quantity</em> of materials and the actual quantity of materials used. It speaks to only the <em>quantity</em> used and nothing else.
An increased cost of the material is not relevant to the quantity of material used because whilst for instance it measures if there was a <em>price change</em> in the material, the materials quantity variance checks if there has been a change<em> in quantity</em>.
Answer: The change in molarity of blood is 0.0187 mol/L
Explanation:
The equation for molarity is given as:
M = m/V
where M is molarity (mol/L)
m = number of moles of solute
V = volume of solvent (Liters)
First step: Determine the number of moles in a specific mass
32g sugar (sucrose: C12H22O11) is dissolved in a 5L of blood.
In order to get the number of moles in a specific mass, divide the number of grams per mole into the size of the sample i.e 32g/(342.30 g/mol) = 0.0935 mol
Second step: Determine the change in molarity of blood sugar.
M = m/V
M = 0.0935 mol /5 L
M = 0.0187 mol/L
Answer: Illegal home use.
Explanation:
An illegal home use is when an additional structure is added to an already existing building, or a building is converted to be used for another purpose other than the original plan or purpose for the building which was approved by the government agency in charge city planning.
Illegal home use can lead to: overcrowding, obstruction of emergency fire exits, and exposing building occupants and neighbors to unsafe conditions.
Converting a residential home to an antique store is an example of illegal home use.
