1.6 Hz

Step-by-step explanation:

I know this was posted a week ago, but, if you still need help:

You can set up a proportion, as follows.

50 / 2 = 40 / x => where x = frequency in Hz,

x = 2*40/50 = 80/50 = 8/5 = 1.6 Hz

Answer:

The answer is 1

Step-by-step explanation:

i) $\dfrac{(5\frac{4}{45} -4 \frac{1}{6})\div5\frac{8}{15} }{(4\frac{2}{3} +0.75)\times3\frac{9}{13}}\times34\frac{2}{7} + \frac{0.3\div0.01}{70} + \frac{2}{7}$

ii) $\dfrac{(\frac{229}{45} -\frac{25}{6})\div\frac{83}{15} }{(\frac{14}{3} +\frac{3}{4})\times\frac{48}{13}}\times\frac{240}{7} + \frac{30}{70} + \frac{2}{7}$

<h3 />

iii) $(\dfrac{(\frac{458}{90} -\frac{375}{90})\times\frac{15}{83} }{(\frac{56}{12} +\frac{9}{12})\times\frac{48}{13}}\times\frac{240}{7}) + \frac{30}{70} + \frac{2}{7}$

<h3 />

iv) $(\dfrac{(\frac{83}{90})\times\frac{15}{83} }{(\dfrac{65}{12} )\times\dfrac{48}{13}}\times\dfrac{240}{7}) + \dfrac{30}{70} + \dfrac{2}{7}$

<h3 />

v) $(\dfrac{(\frac{1}{6}) }{(5\times4)}\times\dfrac{240}{7}) + \dfrac{30}{70} + \dfrac{20}{70}$

<h3 />

vi) $(\dfrac{1}{(6\times5\times4)}\times\dfrac{240}{7}) + \dfrac{50}{70}$

<h3 />

vii) $(\dfrac{1}{120}\times\dfrac{240}{7}) + \dfrac{50}{70}$

viii) $(\dfrac{2}{7}) + \dfrac{50}{70}$

ix) $\dfrac{20}{70} +\dfrac{50}{70}$

x) $= \dfrac{70}{70} \hspace{0.2cm} = \hspace{0.2cm} 1$

Answer:

$3\frac{1}{4}$

Step-by-step explanation:

we have to divide the given distance by 3.

Then we will be able to find the distance between markers.

Given distance is

$9\frac{3}{4} \\=\frac{36+3}{4}\\ =\frac{39}{4}$

Since, there are three markers,

So, we have to divide this distance by 3

So, the distance between markers is-

$\frac{\frac{39}{4}} {3} \\=\frac{39}{4} * \frac{1}{3} \\=\frac{13}{4}$

So, the distance between marker is

$\frac{13}{4}$

Now, we have to convert this into mixed number.

Then, the distance is-

$\frac{13}{4}\\ =3\frac{1}{4}$

As of the 2010 census, there were 3,669 people living in Marlboro, New York. Brooklyn, New York, has 681 times as many people. H

LekaFEV [45]

Answer:

2,494,920

Step-by-step explanation:

We have been given that in 2010 census, there were 3,669 people living in Marlboro, New York. Brooklyn, New York, has 681 times as many people.

$\text{People live in Brooklyn}=681\times 3,669$

$\text{People live in Brooklyn}=2,498,589$

Now, we will subtract 3,669 from 2,498,589 to find the number of people more in Brooklyn than Marlboro.

$\text{People more in Brooklyn than Marlboro}=2,498,589-3,669$

$\text{People more in Brooklyn than Marlboro}=2,494,920$

Therefore, there are 2,494,920 more people live in Brooklyn than in Marlboro that is 680 times the people in Marlboro.
