2.1875 converted into a fraction ? Im am so confused like ... woah ... help ?? [color=#40BFBF][/color] <--- why these words for tha color ??

For a start you can split that decimal up into 2 + 0.1875
now
0.1=1/10
0.18=18/100
0.187=187/1000
0.1875 = 1875/10000
That is how decimals work.
So one answer is just
2 and 1875/10000

Now, if you want to simplify the fraction part then you need to find a common divisor of 1875 and 10000
25 would be a good start. aAnyway you have to cancel down. Do you know how to do that?

[color=#00FF00][/color]
This is the computer language for this colour. The computer doesn't understand 'lime green' but it does understand colour=#00FF00 The hash just means number and the 00FF00 is the number assigned to this shade of green.
There are many computer languages. I assume this is written in HTML (Hyper Text Markup Language) HTML is the most common laguage used on the internet.
I am not very knowledgeable about computer languages so if someone you trust contradicts me, then believe them, or better still, research it on the net and make up your own mind.

88 in . is correct (assuming we're using 22/7 for pi)

cos x + sin x tan x = sec x

One thing about verifying identities is that there may be more than one way to proceed. I always like to convert things to sines and cosines. where possible.

So, proceeding in that manner on the left side, we have:

cos x + (sin x) * ( (sin x) / (cos x) ) = sec x

cos x + ( (sin x)^2 / cos x ) = sec x

Getting a common denominator on the left, we have :

( (cos x ) ^2 + (sin x )^2 ) / cos x = sec x

Now, using the identity (cos x ) ^2 + (sin x )^2 = 1, we have

1/ cos x = sec x

sec x = sec x

Voila!!

Hopes this helps!!

Okay, I found the circumference, which is 88 right? (rounded)
So that's the answer?

CluelessMath:
if the wheels of a cart have a radius of 14in. how many inches does the cart travel each time the wheel turns? (use 22/7 for pi)

It turns the whole circumference of the wheel.
do you know the formula for the circumference of a circle?
you can google it yourself.
If you want us to check your answer you can repost.

It is very simple. Just do the subtraction. I have a feeling that you know this.

First, you have to change the problem to have like denominators. SO, 1/4 would change to 3/12. Then, you do 10/12-3/12. You should get 7/12.

Hope this helps!

14. Divide 28 by 2.

27(-2/3)
Means
27x(-2 divided by 3)
-2 / 3 = -0.6666666666666667
27 x -0.6666666666666667 = -18.0000000000000009
Rounded down
Is -18

Answer to the quiz about (Pierre, Pieter and Peter)
and their three athletes (Édouard, Eduard and
Edward)

First édouard and eduard enter the boat to the other side, eduard drops off and édouard paddles back and picks up pierre. Édouard drops at the other side and pierre paddles back and picks up pieter. They both drop off at the other side. Édouard paddles back again and picks up edward. Édouard drops off at the other side and edward paddles back and picks up peter. They both drop off at the other side.

In essence no athelete is left in th presence of another coach without his coach being present.

More explanation about your problem?

You want to solve this equation? (X and Y)

In the first () x-1y4 you mean, x-1y^4?

The explanation is simple.

You want to know the probability that Robert win.

So you have 200 card that have been sent whit the CORRECT answer.

The put 17 000 cards whit the CORRECT answer in a barrel.

Si Robert have 200 cards on the 17000 cards in the barrel.

200 / 17000

You need to forget the 250'000 because it's not a useful value.
