The solution of the equation when p = -1 is T=3x^{-2}

<h3>How to determine the value of the equation?</h3>

The equation is given as:

T=3x^{2p}

The value of p is -1.

So, we have:

T=3x^{2*-1}

Evaluate the product

T=3x^{-2}

Hence, the solution of the equation when p = -1 is T=3x^{-2}

There is 100 people in each train car so how many people are they in each train there is ten cars in each train and thirty train
snow_tiger [21]

Information given:

- <u>100 passengers in each train car</u>

- <u>10 train cars total</u>

- <u>30 trains total</u>

<em>So we are trying to find the total number of passengers on all 30 trains?</em>

<u />

Step-by-step:

100 x 10 = <u>1,000 passengers per train</u>

1,000 x 30 = <u>30,000 passengers total within the 30 trains</u>

Answer: <u>30,000 passengers</u>

<em>Hopefully this answered your question :)</em>

Y=300-5x in standard form
Akimi4 [234]
<span>y = 300 - 5x

Standard form:
ax + by = c

</span>y = 300 - 5x
<span>5x + y = 300

Then to find the y-intercept, insert a 0 into the 'x'.
5(0) + y = 300
y = 300
The y-intercept is 300.

To find the x-intercept, insert a 0 into the 'y'.
5x + (0) = 300
5x = 300
x = 60

The x-intercept is 60.</span>

The radii of Earth and Pluto are 6,371 kilometers and 1,161 kilometers, respectively. Approximately how many spheres the size of
antoniya [11.8K]
The volume of a sphere is (4/3) (pi) (radius cubed).

The volume of one sphere divided by the volume of another one is

 (4/3) (pi) (radius-A)³ / (4/3) (pi) (radius-B)³

Divide top and bottom by (4/3) (pi) and you have     (radius-A)³ / (radius-B)³
and that's exactly the same as
                                                         ( radius-A / radius-B )  cubed.

I went through all of that to show you that the ratio of the volumes of two spheres
is the cube of the ratio of their radii.

Earth radius = 6,371 km
Pluto radius = 1,161 km

Ratio of their radii = (6,371 km) / (1,161 km)

Ratio of their volumes =  ( 6,371 / 1,161 ) cubed = about <u>165.2</u>

Note: 
I don't like the language of the question where it asks "How many spheres...".
This seems to be asking how many solid cue balls the size of Pluto could be
packed into a shell the size of the Earth, and that's not a simple solution.
The solution I have here is simply the ratio of volumes ... how many Plutos
can fit into a hollow Earth if the Plutos are melted and poured into the shell.
That's a different question, and a lot easier than dealing with solid cue balls.
