My Physics teacher taught me many things, but the most valuable was the acronym RTFQ, which loosely translated means "Read The F***ing Question". In fact, the first formula in Anonymous's answer is wrong, because he didn't follow the RTFQ principle.All of the numbers are ODD. So the equation becomes X + (X + 2) + … Read more
Whoa, Jackieboy. If you have 3 variables, you need 3 equations to solve for them uniquely. As it is, all we have is one: That they sum to A. Even if we fix X at 25, for example, for any given value of A (say, 100), then all we know is that Y + Z … Read more
Simon's right, but the answer is more simple: Any triangle with a base and height that result in the given area is a valid answer. In fact, there are an unlimited number of them. They're height and base are related like this: Let's say Area is A, Height is H and Base is B. So, … Read more
See my comments to Maria Not Telling's answer. You won't remember the formula unless you understand why it works, so I explain it. Use bits of paper, if it's easier to visualize what we're doing.
We could work out the left rectangle's area, and divide by two, and then do the same for the right rectangle, and sum them, but there's a simpler way: Use the big rectangle's area (the same as the two little guys put together). We have to divide it by 2, since each rectangle was only … Read more
Remember how for each of the original rectangles, exactly half of that rectangle was covered by a portion of the triangle? That means that the area of the left portion of the triangle is 1/2 of the left rectangle's area, and the area of the right portion is 1/2 of the right rectangle's area.
But that big rectangle's width is the same as the triangle's width (their corners meet, right?). And its height is the same as the triangle's height. And it's area is its width (same as the base of the triangle) x its height (same as the height of the triangle). Now we're ready to figure out … Read more
Now, each rectangle covers one portion of the triangle; where the two portions meet is the edge where the two rectangles meet. There is no part of the triangle that isn't covered by one of the rectangles. Now imagine taping the two rectanges together along the edge where they meet. When you do that, you … Read more
Now, look at how the triangle's sloping edges rise from the corners on the table up to the top corner (the apex). They divide each of the rectangles exactly in half, from one bottom corner to the opposite top corner. That means that the area of the rectangle that overlaps the triangle is exactly one … Read more
If you're like me, you'd never remember what looks like a completely arbitrary formula. So, try this: Imagine your triangle is standing up on a table, with its base on the bottom. Now you can see how high it is. Next, create two rectangles, each with the same height. Place them edge to edge behind … Read more
Wow. Look at all these posts... This question sure hit a nerve.Well, here goes - I'm a guy, so I'll call it like I see it from the other side. Guys go through stages and cycles of being affectionate and being distant. This is normal. Their quiet times are called "being in the cave", and … Read more
Nuclear plants fueled by Thorium would produce far less (and less toxic) waste; we only use Uranium because the US Navy leadership chose it way back when, and everybody followed them... We can also generate Hydrogen from algae (they do it now), and burn that to form water.But we're asking the wrong question. Sure, we … Read more
Stop doing what you were doing, and stop it 3 months ago. Rinse, Repeat.
Which type of network attack occurs when an unauthorized person tries to persuade a user to share a network ID and password?
This is certainly an attempt to breach security, but it not considered a network attack. A network attack involves attempting to take over or impair the operation of a service component of the network, such as the web servers or the routers and other networking equipment, or quantities of personal computers. For a summary of … Read more
