If you have 6p^4/4p^3 you would subtract the powers when dividing the bases so you're answer would be 3p/2. divide the constants(6 and 4) like you would normally would

6p^4=6p*p*p*p
divided by
4p^3=4p*p*p
-------------------
3p/2

No.  The 6 is over the 4.  So no matter what else is in the fraction,
the 6 is divided by the 4.  In other words, that part of the fraction ...
6/4 ... simplifies to 3/2 .

Settle down and let's look at that problem:

You said:          6 p⁴ / 4 p³

I hope you see that this ugly complicated fraction can be written as
the product of two separate fractions.  It's exactly the same thing as

                        6/4  times  p⁴/p³ .

Simplify the first one:     6/4 = 3/2

Simplify the second one:     p⁴/p³ = p

And the original fraction becomes        6p⁴/4p³  =  3/2 p .

=====================================

Now, if you'll stay with me, I want to take you back to the original
problem, and do it a slightly different way:

Even though the original fraction has both numbers and a variable
in it, the question is actually something that you've done hundreds
of times before ... simplify the fraction !

How do you simplify a fraction ?  (Review)  Find a common factor of
the top and bottom, then divide top and bottom by the common factor.

OK.  We have  6p⁴  and  4p³ .

The factors of  6p⁴  are:  1,  2,  3,  6,  p,  p²,  p³, and  p⁴ .

The factors of  4p³  are:  1,  2,  4,  p,  p², and  p³ .

What do we have for common factors ?  I see ' 2 ' and ' p³ ' .

Divide the top by  2p³ :            6p⁴ / 2p³ = 3p

Divide the bottom by  2p³ :      4p³ / 2p³ = 2

Now, after simplifying, the fraction is  (3p/2)  or  (3/2 p) .

What is the value of x? Round to the nearest tenth.

Answer:

27.5

Step-by-step explanation:

first you find what 30x30 is as A squared plus B squared is equal to C squared. your A is 12 and your C is 30.

so!

30x30 is 900

12x12 is 144

subtract 144 from 900 and you get 756. once you find the square root you get 27.49. then round up to 27.5

Please help!!! How many coefficients does this polynomial have in its complete form, including any missing terms?
frez [133]
-5x^3 + 2x^2 + 1

a coefficient is the number that is multiplied by the variable.For instance, the coefficient of 2x is 2....because 2 (the number) is multiplied by the variable x.

so in ur problem....there are 2 coefficients..-5 and 2.

** the number 1 is not a coefficient, it is a constant...a " loner " with no variables (letters) attached.

** and if u have just the letter...such as n, the coefficient to that is 1 but the one is just not written...it is actually 1n.

okay...I am gonna shut up now :)

Solve the right triangle shown in the figure BC = 1.6in< A=48.8 C =90
yKpoI14uk [10]
Drawing a diagram to represent the information you've given, the only angle we are missing is B.  We can find that by subtracting the two we're given from 180:
180 - 90 - 48.8 = 41.2
<em>m</em>∠<em>B</em> = 41.2°.
We can use the angles and the one side we're given to find the remaining sides.  Since we do not know the length of the hypotenuse, AB, we cannot use sine or cosine.  We must use tangent (the ratio for tangent is opposite/adjacent):
\tan 41.2 = \frac{x}{1.6}
Multiply both sides by 1.6:
1.6 \tan 41.2 = x&#10;\\ 3.67 = x
This is the length of side AC, which is opposite to angle B.
To find the length of AB we can use the Pythagorean Theorem:
(1.6)^2+(3.67)^2=c^2&#10;\\ 2.56+13.4689=c^2&#10;\\ 16.0289=c^2&#10;\\ \sqrt{16.0289} = \sqrt{c^2}&#10;\\ 4=c
The length of side AC, the hypotenuse, is 4 inches.

In 2001, a company marketed 730,000 units of its product. In 2001 its yearly volume was 50% of its volume for 2004. The 2004 vol
Dmitriy789 [7]

Answer:

4000 units

Step-by-step explanation:

In 2001 the total number of marketed units= 730,000

If this number represents 50% of what was marketed in 2004, then the total number of units marketed in 2004 was:

(100/50)× 730,000=1460000

To get the number for each of the 365 days in 2004 we divide the total for 2004 by 365

1460000/365= 4000 units
