One of the main reason why you want to reduce acne redness fast is because you have an important event or meeting to attend. And you can't bear having people staring at your acne redness. At the same time, you don't want to feel embarrassed because of the red blotches on your face especially. Taking oral antibiotics such as tetracycline, doxycycline, minocycline, and erythromycin may decrease redness but it will take some time to see results.
What Is Acne Redness
Acne redness is not a scar. It is an inflammatory response.
How do you get pimple redness in the first place? It begins when excess sebum pass through the walls of the follicle. In the pores, the sebum combines with the dead skin cells, causing the clogging of the pores. This allows P. acnes bacteria to populate...

How to Convert a Percent Grade to Slope in Degrees
Percent grade and slope in degrees both indicate the amount that elevation changes over a certain distance, which determines how steep a hill or slope is. Percent grade denotes the percentage of change in the elevation--for example, if a hill rises 20 feet over a 100-foot distance, it has a 20 percent slope. The slope in degrees indicates the angle between the surface of a hill and level ground.
You can record a hill's slope in degrees or percent.
1. Divide the percent grade by 100.
2. Take the arctangent of this number using a scientific calculator. Your calculator may have an "atan" button, or you may need to press the "2nd" or "inv" button, then the "tan" button.
3. Write "°" after the result to indicate degrees.

You can describe a fraction of a circle by using a percentage or by describing the equivalent angle in degrees. To convert percentage into degrees, you must multiply the total number of degrees in a circle by the percent. Slopes are another entity commonly measured both ways. Percent slope describes the vertical change divided by the horizontal change, or rise over run. Degrees of slope describe the angle of incline. To convert from percent into degrees of slope, you must convert the percentage into its decimal equivalent, then find its arctangent.
Pie charts represent percentages, but the angles of the wedges are measured in degrees.
Circles
1. Convert the percentage into its decimal equivalent by dividing it by 100. For instance, 45 percent equals 0.45.
2. Multiply...

How to Convert Angle Degrees to Slope
An angle can represent a slope, and a slope can be measured as an angle. A slope is the measured steepness of growth or decline over a specific amount of distance. In geometry, calculation of a slope develops from a ratio of a change of y-coordinates, also known as the rise, over a change in x-coordinates, known as the run. When given the degrees of an angle representing the slope, you can calculate the slope as both a gradient with the ratio in decimal form and a percentage by employing the trigonometric tangent function.
1. Obtain an angle in degrees. For this example, let the angle by 40 degrees.
2. Calculate the tangent function of the angle with your calculator. For this example, the tangent of 40 degrees equals approximately 0.83901. This is the slope as a gradient.
3. Multiply...

How to Convert an Angle From Degrees to Decimal
Degree measurement of angles can take two forms: one form is when the distance between individual degree units are measured in minutes and seconds, and the other is decimal notation. When measured with minutes and seconds, the measurement appears as d° m' s", where "d" is the degree amount, "m" is the minute amount and "s" is the second amount. Both the minute and second count follow from a normal hour, so a degree is composed of 60 minutes, and a minute is composed of 60 seconds. Conversion from this form to the decimal form helps in simplifying angular mathematical operations.
1. Find an angle measured in degrees. For this example, the angle is 44° 15' 36".
2. Multiply the minutes of the degree by 1/60 and the seconds of the degree by 1/3,600, then sum the two products....

How to Convert Fractions From Seconds to Minutes
Converting a number of seconds given in fractional form to its equivalent value in minutes is a task you might do when preparing an estimate of how many times a certain task that takes less than a minute could be performed in a span of time that is greater than a minute but less than an hour. Whatever the case, conversion of a fractional value of seconds to minutes is a simple matter of fractional multiplication.
You can convert seconds given in fraction form by multiplying the denominator by 60.
1. Convert the supplied value for seconds into a simplified fraction. For example, a value of 2 1/2 seconds can be expressed as 5/2 seconds.
2. Multiply the denominator of the fraction by 60 to obtain its equivalent value in minutes, as dividing a fraction by 60 is the same thing as multiplying...

How Much Can a Contract Laborer Make Before Paying Taxes?
When you provide services as a contract laborer or independent contractor, the Internal Revenue Service treats you as being self-employed. However, you have the same income tax obligations as an employee who earns a salary. The only difference is the way you report this income and how much money you can make before you must file a tax return. Unlike employees, contract laborers are responsible for paying self-employment tax directly to the IRS.
Contractor Filing Requirements
If you earn a substantial amount of income during the year as an independent contractor, you must report your earnings on a Schedule C or C-EZ attachment to your tax return. The IRS requires this even if you earn other income during the year as an employee. As of 2011, you must file a Schedule C with...

How to Figure Income Tax on Contract Labor
Receiving income from contract labor means filing the long form for your personal income taxes. You will need to fill out and file either a Schedule C for a business or a Schedule F if your income was in the agricultural field. Contract labor is also subject to Self-Employment tax. The Self-Employment tax is a contract laborer's way of contributing to their Social Security fund.
1. Collect information about contract labor income and legitimate expenses you may be able to deduct. For example, if you are working as a freelance writer, you will need to collect all the information about who you worked for and the amounts you were paid. Legitimate expenses can include the cost of your computer, postage, telecommunications, including Internet service, and office expenses.

How to Calculate Taxes When Self Employed
Self-employed people enjoy the convenience of being their own boss and being able to set their own schedules. However, they are completely responsible for paying their own taxes. Self-employed individuals must pay self-employment taxes and estimated taxes. Self-employment taxes consist of all Social Security and Medicare taxes. Estimated tax consists of the paying quarterly on money that is not subject to withholding.
Calculating Self-Employment Taxes
1. Use Schedule C or Schedule C-EZ to determine what your net income for the year is. Net income typically equals your total business revenue minus your total business expenses, such as operations costs.
2. Find your net earnings by multiplying your net income by 92.35 percent. If your net earnings are...
