maw [93]

Answer:

0.514

Step-by-step Explantion:

Denominator = 500 = 2^2 * 5^3

257/500 = 257/2^2*5^3 = 2*257/2*2^2*5^3 = 514/2^3*5^3 = 514/(2*5)^3 = 514/10^3 = 0.514

Answer:

<h2>x = 4</h2>

Step-by-step explanation:

$x + 2 = \frac{x}{4} + 5$

Multiply through by 4 to eliminate the fraction

That's

$4x + 8 = \frac{x}{4} \times 5 + 5 \times 4 \\ 4x + 8 = x + 20$

<u>Subtract x from each side</u>

That's

$4x - x + 8 = x - x + 20 \\ 3x + 8 = 20$

<u>Subtract 8 from each side</u>

$3x + 8 - 8 = 20 - 8 \\ 3x = 12$

<u>Divide both sides by 3</u>

$\frac{3x}{3} = \frac{12}{3}$

We have the final answer as

<h3>x = 4</h3>

Hope this helps you

Describe all equation of motion

wel

Answer:

<u>First</u><u> </u><u>equation</u>

from definition of acceleration:

$a = \frac{change \: in \: velocity}{time} \\ \\ a = \frac{v - u}{t} \\ \\ at = v - u\\ { \boxed{v = u + at}}$

<u>Second</u><u> </u><u>equation</u>

from displacement:

$s = (average \: velocity) \times time \\ s = ( \frac{v + u}{2} ) \times t \\ \\ 2s = (v + u)t$

but v is u + at :

$2s = \{(u + at) + u \} \times t \\ \\ 2s = (2u + at)t \\ 2s = 2ut + {at}^{2} \\ s = \frac{2ut}{2} + \frac{a {t}^{2} }{2} \\ \\ { \boxed{s = ut + \frac{1}{2} {at}^{2} }}$

<u>third</u><u> </u><u>equation</u>

from displacement:

$s = ( \frac{v + u}{2} )( \frac{v - u}{a} ) \\ \\ 2as = (v + u)(v - u) \\ 2as = {v}^{2} - {u }^{2} \\ \\ { \boxed{ {v}^{2} = {u}^{2} + 2as }}$

s » displacement

v » final velocity

u » initial velocity

a » acceleration

t » time
