Answer:

7500 joule

Step-by-step explanation:

100 m/s <<< c(= 3 x 10^8 m/s) or speed of light.

So, at this velocity, mass is constant.

Therefore,

KE = ½ mv²

KE = ½ x (1.5) x (100)² J

KE = 7500 J or 7.5 kJ

Данная фигура состоит из 6 одинаковых квадратов . Ее периметр равен 126 см. чему равна площадь фигуры?

hammer [34]

Answer:

The length of each side of square is 9 cm

Step-by-step explanation:

<u><em>The question in English is</em></u>

The given figure is made up of 6 identical squares.The perimeter of the figure is 126 cm.what is the length of each side of square?

The picture of the question in the attached figure

Let

x ----> the length side of each square

we know that

The perimeter is the sum of the borders of the figure

In this problem

$P=14x$

see the attached figure N 2 to better understand the problem

we have

$P=126\ cm$

$14x=126$

solve for x

$x=9\ cm$

therefore

The length of each side of square is 9 cm

Situation 1: In Lakeville, Melinda’s television cable bill is a flat rate of $50 per month, plus $1.50 for every movie she rents

olchik [2.2K]

Answer:

situation 1 : flat rate of 50....1.50 per movie.....after 1 month her bill is 66.25

66.25 = 1.50x + 50

situation 2 : flat rate of 60....1.25 for every movie...

y = 1.25x + 60

both situations have a flat rate fee plus a charge for every movie. In situation 1, u can solve for x (the number of movies rented) because u know how much she was charged. However, in situation 2, without more information, u cannot solve this equation...what u would need to solve it would either be the number of movies rented or the total bill showing what she was charged. So basically, in situation 1, u are given more information then in situation 2.....enough information to be able to solve for the variable x...whereas, in situation 2, u are not given enough info to solve for a variable and get a numerical answer
