I will give Brainliest if you can prove whether the story of Archimedes and his method to find the density of the gold crown if true. Mass of crown = 2 kg
( the whole is covered in gold and it has 8 diamonds of 1 kg. ) Find its volume and use the density of each substance.
Disclaimer : The examples are not specified. Just find out the volume. Also wrong answer will be reported as well as be given 1 star and no thanks.

Explanation:

kg you just move up and down the stairs

Answer from: getzperez1962

This is easy.

To find, let me provide first the densities of the materials given below :

Gold = 19,300 in kg and 13.9 in g

Diamond = 3520 in kg and 3.51 in g

Mass of whole crown = 2 kg.

Explanation:

Here we have to use the formula Density = Mass / Volume

So,

D = M / V

17.41 = 2 / V

V = 34.82 g

I gave answer in grams

So, still some work is left, lets do it.

Volume is given in grams, so I have to convert it to kilograms since you provided to answer it in Kilograms.

1 kg = 1000 g

2 kg = 2000 g

34.82 g = 34.82/1000

=0.03482 in kg

Whole volume is 0.03482 cm^3.

Answer from: Quest

$\frac{2y^2-5y-7}{6y^2+10y+4}-\frac{7}{9y^2+6y}=\frac{6y^2-21y-14}{6y\left(3y+2\right)}$

step-by-step explanation:

we are given

$\frac{2y^2-5y-7}{6y^2+10y+4}-\frac{7}{9y^2+6y}$

we have to simplify it

firstly, we will factor it

$2y^2-5y-7=\left(y+1\right)\left(2y-7\right)$

$6y^2+10y+4=2\left(y+1\right)\left(3y+2\right)$

$9y^2+6y=3y(3y+2)$

$=\frac{\left(y+1\right)\left(2y-7\right)}{2\left(y+1\right)\left(3y+2\right)}-\frac{7}{3y(3y+2)}$

now, we can cancel like terms

$=\frac{\left(2y-7\right)}{2\left(3y+2\right)}-\frac{7}{3y(3y+2)}$

now, we can combine it

$=\frac{3y(2y-7\right)}{6y\left(3y+2\right)}-\frac{7\times 2}{6y(3y+2)}$

$=\frac{3y(2y-7\right)-14}{6y\left(3y+2\right)}$

$=\frac{6y^2-21y-14}{6y\left(3y+2\right)}$

so, we get

$=\frac{6y^2-21y-14}{6y\left(3y+2\right)}$

Answer from: Quest

sleep paralysis is a parasomnia, events associated with sleep.

sleep paralysis happens when you are in the middle of waking up or falling asleep. it is the feeling of being conscious but unable to move. it definitely involves hallucinations.

i had a friend that had sleep paralysis and he told me a story one time where he was laying in bed and he couldn't move his body no matter how hard he tried and there was someone standing in the corner of his room coming towards him. he couldn't move and you can't "wake up" because you are already conscious. sometimes sleep paralysis can be triggered by frequent waking up during the night based off of multiple trips to the bathroom, or if you had ever been abused, sleep paralysis can start happening from things like that.
