Let me go ahead and help you start on these questions...
From the question we can see that we are talking about 2 jets, but we only are concerned with a single variable. Can you tell me the variable?
Let t = time that the plane was in flight...
I wish I was able to attach some pictures to the post to illustrate, but let me go ahead and explain the best I can with just writing.
Whenever we want to shift a function, in any direction, our goal is to manipulate the variable...
This question is testing whether you know and understand your trig tables. Here is our table:
Angle | Sin (Angle) | Cos(Angle) | Tan (Angle)
0 | ...
To start off, we have to determine how many equations we need to solve this problem. Seeing that the problem involves a "larger number" and a "smaller number" and that we are given 2 different constraints we can be assured that we will need 2 variables...
The first thing we can notice from this question is that we need two variables to write our system of equations(Ruth's age and the son's age).; this also means that we need two equations!
let R=Ruth's Age
let s= Ruth's...
Let's start off by defining some rules.
1) please no one post answers directly on this post, rather send all answers to me via a message. Comments will be deleted and the person will be disqualified from all future contests.
2) The first 5 people to respond correctly to this post will receive a free 1 hour tutoring session via the online platform in any subject...
In the spirit of giving, starting on 11/29/2013, I will be offering a few brainteasers/ trivia questions where the first 3 people to email me the correct answer will receive a free, one hour, tutoring session in any subject that I offer tutoring for (via
the online platform)! That's right free! Get your thinking hats on everyone!
Let me start by saying very interesting and "outside of the box" question. Although I don't think many can really give you a precise answer (including myself), I did find an interesting article that you may find interesting. Take a look at it and let me
So it turns out that there are really only 2 things that affect the velocity of a wave in a medium.
The medium's change in shape (elasticity)
The medium's change in motion (inertia)
This illustrates a pretty interesting concept of wave physics. Whether a turtle is crawling...
This is a really good question! Not only is it a favorite topic for the algebra regents, but it also tests how comprehensively we understand equations in math.
We have to start off by recalling to memory that a straight line (also called a linear equation)...
Jamila Q. gave an awesome response, however there may be another solution depending on your question. You see:
(5/6)t "which is what Jamila Q. solved" is very different than 5/(6t). If you notice, in the first expression t is in the numerator, which is what Jamila...
Here is a page that I made for WyzAnt!
When you get problems like this, its great to start with a picture. I can't draw it here, but if you draw a giant circle, you can see that the diameter (length from one side of the circle to the other) in the middle of the circle is a LOT bigger than the
length of a line drawn...
From my experiences in tutoring, I have come to realize that one of the biggest struggles for the young students in math is understanding fractions. When they see a fraction, they would rather leap off the Brooklyn Bridge than attempt to understand what
it means. In their defense, fractions are one of the more complicated subject matters in mathematics. It's difficult to understand how to do...
Economics is a fragile and often overlooked subject matter. It effects every one of our lives, whether we want it to or not. Will we have a house to sleep in, can we afford college, what are we going to eat tonight, do I get that 42 or that 56 inch TV?
Sadly, even though every person's life is influenced by our economic state, a surprisingly small amount of people understand it or even...
