We all know that color coding is important because it helps us to quickly organize things based on visual cues. As students in high school, we used differently colored page tabs to denote different subject matters, and some of us color code file cabinets for easier and faster access. The same principle goes for this tutorial, which teaches you how to color code a knitting loom.
In this Education video tutorial you will learn how to avoid wrong answers on the SAT critical reading area. Five principles to keep in mind are rephrase the question and predict the answer, answer the question being asked, find evidence in the passage, extreme answers are suspicious and finally remember a little wrong is all wrong. To rephrase the question, read 2 lines before and after, ask the question in your own words and find the answer choice that best matches your prediction. Now comi...
This is a survival video which shows how to make a fire out of chap stick and cotton balls. This is called the wicks/wax principle. For the wick, cotton balls are used. For the wax, any petroleum based product is good. In this case chap stick is used. Take a big chunk of chap stick out of the tube, about 1 inch. Smear the chap stick into the cotton ball. This will evenly distribute the chap stick throughout the cotton ball. Spread out the chap stick filled cotton ball so that it creates a big...
In this video, the instructor shows how to identify the percentage change using proportions. When a given quantity increases or decreases by certain amount then we can calculate the percentage change in the quantity, which can be either increase or decrease based on the new value of the quantity. To solve these kind of situations you should know that the ratio of amount of increase (or decrease) of an amount to its original amount is equal to the ratio of percentage increase (or decrease) to ...
Here we look at squaring expressions that involve radicals because people tend to make some common mistakes while solving such expressions. Take 5 times the square root of y quantity squared, the answer here is not 5y. Here's the reason, square means to multiply something with itself so the square of 5 root y would be 5 root y into 5 root y. So 5 x 5 is 25 and under root y into under root y equals just y so the answer will be 25y.
You can solve any proportion using the fundamental rule of proportions. First you must build the proportion if you are given a word problem. Decide using logic whether it is a direct proportion (more on one side means more on the other). If so, find the parts of the equation that use the same units and make a fraction with these, putting the smaller number on top. The number left over is linked with one of the other two numbers in the fraction--use logic to figure out which. Put it in the sam...
Learn how to calculate simple interest with step-by-step instructions using the formula I=prt. Simply defined, interest equals principle times rate times time.

Finding horizontal asymptotes is very easy! Not all rational functions have horizontal asymptotes. the function must satisfy one of two conditions dependent upon the degree (highest exponent) of the numerator and denominator. If the degree of the numerator is equal to the degree of the denominator, then the horizontal asymptote is y= the ratio of the leading coefficients. If the degree of the denominator is greater than the degree of the numerator then y= 0. If the degree of the denominator i...

To organize the closet you have to start with the donate or keep principle. Start your piles and get rid of the stuff that you no longer need. You can also have a "can't decide" pile that you put somewhere until you decide but the general rule is, if you haven't used it in a year you probably never will. There are six areas in a closet. First is short hang. It is the most common and includes shirts, blouses, and folded pants. Short hang can be hung in one level or double hang levels. Hangers ...
One of the easiest ways to measure body fat is by using hydrostatic weighing. It is based on Archimedes' principle, the law of buoyancy. It works by calculating body fat from measuring the amount of displaced water after a person has been immersed under water. Since muscle is denser than body fat, a person who has more muscle will displace less water than a person of the same weight with more body fat. This test is usually performed for a couple times for averaging accuracy. If the test is do...

But the widespread use of databases naturally invites a slew of vulnerabilities and attacks to occur. SQL injection has been around for awhile, and as such, there are many defense methods in place to safeguard against these types of attacks.
Because of the way Google Play works, Android has a "bad app" problem. Google allows any developer to upload an app to the Play Store, regardless of if it works, how it looks, or whether or not it can harm users. Malware scanning happens primarily after apps are uploaded, and though Google has recently taken steps to safeguard users with its Play Protect program, you don't have to depend on them.
