The angle generated by the hour hand measures -270° or -4.71 radians, and we will see that the angle generated by the minute hand is 12 times the one generated by the hour hand.
How to get the angle generated?Remember that in a complete rotation we have an angle of 360°, and in a complete rotation we have 12 hours, then there is a relation:
12 hours = 360°
1 hour = 360°/12 = 30°
From 9:00 a.m to 5:00 p.m. there are 9 hours, so the angle that the hour hand does is:
A = 9*(30°) = -270°
(the negative sign is because this angle is measured clockwise)
Now we can write this in radians, remember that:
3.14 radians = 180°
Then:
1 = (3.14 rad/180°)
Then:
270° = -270°*(3.14 rad/180°) = -4.71 rad
What is the angle generated by the minute hand?Each hour that passes, the minute hand does a complete revolution. Then in 9 hours, the minute hand does an angle of:
A = 9*(-360°) = -3,240°
To compare this angle to the one generated by the minute hand we take the quotient:
-3,240°/-270° = 12
So this angle generated by the minute hand is 12 times the one generated by the hour hand.

7-3 additional practice multiplying special cases envision algebra 1
An example of additional practice multiplying special cases envision algebra 1 is solving Linear equation. An example is given as 4 + (3x-1/2) = 9.
What are special cases envision algebra 1?
Envision Algebra 1 is one type of course that needs a good background on Pre-algebra functions. It is a type of algebra that starts from Linear Equations up to polynomials and factoring.
To solve for the above question, one has to separate the fraction on one side of the equation. This can be done by subtracting 4 from the two sides of the equation.
So, 3x-1/2 = 9 - 4
3x-1/2 = 5
The you have to multiply the 2 sides by using the denomiator 2 and so it will be:
3x-1 = 5 * 2
3x - 1 - 5 * 2
3x - 1 - 10
Then you rearrange like terms together.
3x - 10 + 1
3x = 11
x = 11/3
So therefore, x = 11/3

Determine the empirical formula of a compound containing 47. 37 grams of carbon, 10. 59 grams of hydrogen, and 42. 04 grams of oxygen. In an experiment, the molar mass of the compound was determined to be 228. 276 g/mol. What is the molecular formula of the compound? for both questions, show your work or explain how you determined the formulas by giving specific values used in calculations
Considering the definition of empirical formula, the empirical formula is C₃H₈O₂ and the molecular formula is C₉H₂₄O₆.
Definition of empirical formulaThe empirical formula is the simplest expression to represent a chemical compound, which indicates the elements that are present and the minimum proportion in whole numbers that exist between its atoms, that is, the subscripts of chemical formulas are reduced to the most integers. small as possible.
Empirical formula in this caseIn this case, you have:
Carbon (C): 47.37 gramsHydrogen (H): 10.59 gramsOxygen (O): 42.04 gramsThen it is possible to calculate the number of moles of each atom in the molecule, taking into account the corresponding molar mass:
Carbon (C): [tex]\frac{47.37 grams}{12 \frac{g}{mole} }[/tex]= 3.95 molesHydrogen (H): [tex]\frac{10.59 grams}{1 \frac{g}{mole} }[/tex]= 10.59 molesOxygen (O): [tex]\frac{42.04 grams}{16 \frac{g}{mole} }[/tex]= 2.63 molesThe empirical formula must be expressed using whole number relationships, for this the numbers of moles are divided by the smallest result of those obtained. In this case:
Carbon (C): [tex]\frac{3.95 moles}{2.63 moles }[/tex]= 1.5Hydrogen (H): [tex]\frac{10.59 moles}{2.63 moles }[/tex]= 4Oxygen (O): [tex]\frac{2.63 moles}{2.63 moles }[/tex]= 1Finally, since in the empirical formula the numbers of moles must be expressed in whole numbers, the ratio of atoms is multiplied by some number with which everything is obtained in simple whole numbers (in this case by 2):
Carbon (C): 1.5× 2= 3Hydrogen (H): 4× 2= 8Oxygen (O): 1× 2= 2Therefore the C: H: O mole ratio is 3: 8: 2
Finally, the empirical formula is C₃H₈O₂.
Molecular formulaTo obtain the molecular formula you must relate its molecular weight (PMc) with the molecular weight of the empirical formula (PMfe).
PMfe= PM (C₃H₈O₂)= 76 g/mole
The molar mass of the compound (PMc) was determined to be 228.276 g/mol. Dividing this mass PMc by the molar mass of the empirical formula PMfe gives:
228.276 g/mol ÷ 76 g/mole= 3
This means that in the molecular formula there are 3 unit formulas (empirical formulas), so it is necessary to multiply the number of all atoms by 3.
Then, the molecular formula is C₉H₂₄O₆.
