Boric Acid is often used to treat or eradicate bedbugs. However, it doesn't work particularly well. It has to be ingested to kill them, but they don't necessarily consume it. There would need to be a bait that they can ingest that contains boric acid. Unfortunately, people are the bait that they respond to. Cockroaches, on the other hand, ingest it, because they clean themselves. Therefore, it gets ingested in that way.
In order to combine like terms, you need to look at the variables. Terms can only be combined if the variables are all identical. The first thing that you would have to do is look for matching variables. In the example, x + 2x5 + y2 - 9x - 2x5 + 5y2, you should try to see which ones match. Then, group them together. Match the x's with the x's and the y's with y's. Therefore x - 9x = - 8x. 2x5 - 2x5 = 0. Y2 + 5y2 = 6y2.
In order to add mixed number in fractions, in a math problem, you will need to focus on the denominator. The denominator is the lower number in the fraction. The top number is called the numerator.
To use yoga exercises to wake up and stay awake at work, begin by doing breathing stretches: i.e. cow to cat stretches. Inhale, expanding your chest out for the cow stretch, and exhale concaving your chest into the cat stretch. Next, do side stretches from left to right. Repeat these.

Webbing is not only used in sports like rock climbing and caving, but it also comes in handy in camping and hiking. This video shows you how to tie two webbing ends together to make a loop that will not come off. A square knot does not work for webbing as it will slip through, therefore a water knot is used. Take 4 inches (10 cm) from one marked end and tie an overhand loop. Ensure that the webbing is not twisted. Slip the other end in the knot and trace the second end around the overhand kno...

Eddy Currents are little circles of electricity created when metals are moved by magnets or even when magnets are moved by metals. To understand this practically take a regular piece of cardboard and drop it in between a horse shoe magnet. It drops normally with out being effected by the magnet. This is because the cardboard does not conduct electricity. Therefore it does not cause any eddy currents. But instead if you use an aluminum piece in the same way, it falls very slowly, because alumi...

This video shows you how to calculate the percentage yield in chemistry. To find the percentage yield, you will need to divide the actual yield by the theoretical yield. Then, multiply it by 100: i.e. % yield = actual yield/theoretical yield x 100. An actual yield is the amount of a substance produced in an actual laboratory experiment. It is based on an actual physical measurement of a quantity. The theoretical yield is the yield as is calculated on paper: i.e. through calculations. Therefor...
Shelley Lovett from childcareland demonstrates a fun activity involving finger paint that parents can do with their children. She uses finger paints and a pan to make a virtual canvas that is self contained and easy to clean up. She first recommends that only one color be used. She indicates that by using multiple colors, it may result in a brown ugly color and therefore should be avoided. She then spreads the paint onto a flat pan. After the paint is on the pan, parents and children are able...

In this algebra video the instructor shows how to work with complex numbers. When you have a positive number under the square root, you can easily find its value by writing it in the form of product of numbers, and then solving. That is, to find the square root of a positive number, you can find another number which multiplied by itself gives the original number. This new number becomes the square root of the original number. But when you are asked to find out the square root of a negative nu...

This video tutorial shows you the proper way to find the GCF, or greatest common factor. While this is not necessary, the video shows a method of drawing a T chart. List both the numbers that you need to find the GCF, then list there factors, including the number 1. Once you display your factors of both numbers it is a clear cut visual of what the GCF is. In the case of the problem on the video the number 4 has factors of: 1, 2, 4 and the number 20 has factors of: 1, 2, 4, 5, 10, and 20. Ther...
It's simple: if you've got a brushed motor, you'll want to break it in under controlled circumstances before taking it out into the world. Why break in your engine? The main idea of breaking in your engine is to wear down your engine's brush so as to maximize surface contact with the commutator, reducing resistance (and therefore waste energy) and thereby increasing power. For detailed instructions on breaking in your remote control vehicle's engine, watch this RC hobbyest how-to.
This video shows you how to convert temperatures from Fahrenheit(F) to Celsius(C). In the video, the example of 75 degrees F is used. The formula for converting Fahrenheit to Celsius is given by temperature in Celsius= (temperature in Fahrenheit- 32)/1.8. So for 75 degrees F we take 75 in place of temperature in Fahrenheit. Therefore the equation becomes (75-32)/1.8=C . Further 43/1.8=c and finally C= 24. Hence 75 degrees Fahrenheit= 24 degrees Celsius . This conversion is used as Celsius is ...
This is the video about how to find the equation of a tangent line. As you may recall, a line which is tangent to a curve at a point a, must have the same slope as the curve. Therefore, the slope of the tangent is m = lim f(a + h) - f(a) h-->0 h Since the slope equation of the tangent line is exactly the same as the derivative definition, an easier way to find the tangent line is to differentiate using the rules on the function f. For example, Find the slope of a line tangent to the function ...

In this tutorial the author shows how to find out the volume of a cube. The author shows first to mark the length of the cube and substitute it in the formula for volume of the cube which is s*s*s, where s is the length of the cube. Therefore the volume of a cube is nothing but the length of the cube multiplied to it self three times. By following the method given in this tutorial you can easily compute the volume of a cube with a given length.
Are math problems getting you down? Well this should be of some help. Here is how to find a missing angle inside of a triangle. Now the first thing to remember when solving this type of question is that the sum of all the three angles inside a triangle is equal to 180 degrees. Therefore, whenever we have two of the three angles inside the triangle, all we have to do in order to obtain the missing angle is to add up the two known angles and subtract the total from 180 and we will get the missi...

This video shows you how to easily remember "greater than" and "less than" math symbols. The first thing you have to remember is that "less than" symbol looks like the letter L ("less than" symbol is "<"). When you see this sign, remember that < looks like L and means "less than". The other symbol, "greater than" does not look like the letter L, therefore it cannot be "less than" and it's easier to remember. The "greater than" symbol is ">". That's it! Good Luck!
This video tells you how to find a slope of a parallel / perpendicular to it. In the equation y = mx + c, m is the slope. To calculate the slope of a line that is parallel to another line, you have to consider the rule m1 = m2 which means slope of the first line m1 is equal to the second line m2, if both the lines are parallel. Take the equation y = 2/3x - 7.2/3 is the slope. According to the rule m1 = 2/3 and so m2 = 2/3.Now to calculate the slope of perpendicular line you have another rule ...
This video shows a tutorial of adding fractions. The first example shows a fraction that has like denominators so all you had to do is add the denominators. In the second example it shows two fractions that do not have like denominators. Therefore, you need to find the greatest common factor among the two denominators. Once this is found, you multiply the fraction on both the numerator and denominator to make both of the fractions match. Then all that is left is to add the numerators to finis...
What is the difference between a F1.8 lens and a F5.6 lens? It's really very simple! F8.1 has a much larger lens, and therefore it allows more light to pass through. There are several benefits in having a larger lens. Number one: The quality of the background is improved. Number two: Your focus speed is faster. Number three: Low light ability is better. F1.8 lens are a professional level. F5.6 lens are the commercial kind. For a higher quality photo, you might consider using a larger size lens.
