You can do this by arranging the numbers with a simple method.

20 m / 1 sec = x m / 500 sec

You can now cross multiply (multiply each numerator by the other fraction's denominator).

20 * 500 = 10,000

1 * x = x

x = 10,000

This means that in 500 seconds, Mike can ride his motorcycle 10,000 meters!

That's a really fast motorcycle, in my opinion!

P.S. Sorry if I misunderstood the question. I think you made a typo and forgot to type how many seconds it takes for Mike to ride 20 m!

Let me explain in depth.

y = mx + b

m is your slope. That is the steepness of your line. It is expressed as rise over run, which means the number of spaces to the right over the number of spaces up.

Ex.

The slope of the points (0, 0) and (1, 2) would be 2.

x is your x-coordinate. It is where is point is on across the x-axis.

b is your y-intercept, or "starting point." This is where x is equal to 0.

Ex. A y-intercept of 8 would mean (0, 8) is a point on your line.

y is your y-coordinate. It is what the formula equals, and is also where the point is on the y-axis.

Hope this helped!

P.S. I wouldn't say you were dumb for not understanding a concept right away! However, I hope this explanation keeps you from being "the dumb kid in class."

Hi, Guest!

Please do not take offense, but I suspect that you are just posting all of your homework on the forum without trying!

1. This forum actually has a calculator that can be accessed by clicking the "Home" tab at the top of the page.

2. The forum is meant to help you with your homework, not do it for you.

For us to help you, it would aid us greatly if you could show us your work before posting... 

Thanks!

We know the formula of the area of a square is length * width.

If the area is 9, that means l * w = 9.

The notebook is square, which means all sides are equal.

We can conclude that length = width.

That means w^2 = 9.

(Note: I am using width for this example, but you can also use length.)

This can be changed to the square root of 9 = w.

The square root of 9 is 3, therefore w = 3.

Length and width are equal, which means every side must have a length of...

3

Oh no! I've logged in and it seems that I've caught the cold! 

So, Guest, let's solve this step by step.

First, find the LCD (least common denominator) of each fraction, which in this case is 10.

7/10 = 7/10

1/2 = 5/10

Now we have...

7/10 - 5/10

This equals 2/10, which simplifies to 1/5.

Therefore, 7/10 - 1/2 = 1/5.

This answer cannot be an improper fraction or mixed number...

Maybe you could elaborate?

Thanks!

Okay, it's been a while.

The answer is...

Magnusson got the money!

Both him and the woman told the truth.

Magnusson claimed to be the Amazing Alexis' grandson...

and the the woman claimed that the Amazing Alexis was not Magnusson's grandfather.

It was overlooked by all except Guest (#2) that the Amazing Alexis was in fact female!

There are an infinite amount of numbers, so yes, there is.

Ex.

Gogolplex + 1

or Gogolplex * 4

If you think of a number, there is always a greater one (you know, excluding infinity...)

Evaluate the right side...

2+21000 = 21002

Now you have...

2x = 21002

Divided both sides by 2 to make 2x into x...

2x/2 = x

21002/2 = 10501

Therefore...

x = 10501

I looked again, and the second problem doesn't really make much sense.

It's asking the probability of Jack picking red if he ate one.

How would we know which color he ate?

IDK, but maybe if you want a clear answer, you could rephrase the question?

Thanks,

Hi, BruceWayne.

CPhill is correct for the second question.

The question is asking what the probability of Jack picking a red one and eating it, not the probability of picking a red after he eats one of them.

6 red / 18 total

simplifies to

1/3

1/3 is the answer.

(BTW, 6/17 cannot be simplified any further than it already is.)
