(8.08×10^-10)÷(4.0×10^-3) in scientific notation?

saw5 [17]

Answer:

$\large\boxed{2.02\times10^{-7}}$

Step-by-step explanation:

The scientific notation:

$a\cdot10^k\\\\1\leq a$

We have:

$(8.08\times10^{-10})\div(4.0\times10^{-3})\\\\=\dfrac{8.08\times10^{-10}}{4.0\times10^{-3}}\\\\=\dfrac{8.08}{4}\times\dfrac{10^{-10}}{10^{-3}}\qquad\text{use}\ \dfrac{a^n}{a^m}=a^{n-m}\\\\=2.02\times10^{-10-(-3)}\\\\=2.02\times10^{-7}$

If d = 2, what is the value of 8/4−d? 1 43 4 0

Arada [10]

To solve this plug 2 in for d in the equation like so:

$\frac{8}{4} - 2$

The fraction $\frac{8}{4}$ can be simplified to 2.

How I found this:

The greatest common factor of 8 and 4 is 4.

If we divide 8 by 4 you get 2

If you divide 4 by 4 you would get 1

That gives you the simplified fraction:

$\frac{2}{1}$ Which is the same as simply 2

Now we have the expression:

2 - 2

^^^ A number subtracted from itself is always zero

The answer is:

4p+25=6(p-3)-3(4-3p)

Wewaii [24]

P = 5 .............................................
this is how=

first you expand the second equation
<span>25 + 4p = -18 + -12 + 6p + 9p
</span>
then you add the like terms in the second equation:
25 + 4p = -30 + 15p
then this is how=
25+30 = 15p -4p
55=11p

p= 5
