Answer:
You have to replace x for each density
Step-by-step explanation:
Density = Mass / Volumen
1,000 g = 1 kg
1,000,000 cm^3 = 1 m^3
g/cm^3 = 1000 kg/m^3
Using density as x
![volumen \: = \frac{50000}{x} \\ volumen \: sphere \: = 4\pi {r}^{3} \\ 4\pi {r}^{3} = \frac{50000}{x} \\ r = \sqrt[3]{ \frac{50000}{4\pi {x}^{} } }](https://tex.z-dn.net/?f=volumen%20%5C%3A%20%20%3D%20%20%5Cfrac%7B50000%7D%7Bx%7D%20%20%5C%5C%20volumen%20%20%5C%3A%20sphere%20%5C%3A%20%20%3D%204%5Cpi%20%7Br%7D%5E%7B3%7D%20%20%5C%5C%204%5Cpi%20%7Br%7D%5E%7B3%7D%20%20%3D%20%20%5Cfrac%7B50000%7D%7Bx%7D%20%20%5C%5C%20r%20%3D%20%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7B50000%7D%7B4%5Cpi%20%7Bx%7D%5E%7B%7D%20%7D%20%7D%20)
1) 3x-7y=2
2) If you're solving for x, you want to isolate it, so move the -7y to the right:
3x = 7y + 2
3) Now, to get x by itself, you divide both sides by 3
3x/3 = (7y + 2)/3
4) You get:
x = 7/3y + 2/3
Answer: b) 3
<u>Step-by-step explanation:</u>
From K to L the y-length is 2 and the x-length is 1
From K' to L' the y-length is 6 and the x-length is 3
Therefore, J'K'L' is 3 times as large as JKL so the dilation is 3.
Answer:
do a 3 by 3
Step-by-step explanation:
three across and three up
The energy is compared based on the information given below.
<h3>How to illustrate the energy?</h3>
Energy released by burning 1 kilogram of element A = EA = 5.1 * (10)8
Energy released by fission of hydrogen in 1 kilogram of element B = EB = 1.3 * (10)10
Therefore,
Ratio = EB / EA = 1.3 * (10)10 / 5.1 * (10)8 = 25
Thus, the fission of 1 kg of element B releases 25 times as much energy as burning 1 kilogram of element A.

<u>The other part of the question:</u>
Energy released by burning 1 kilogram of element A = 5.1 times 10 Superscript 8
Energy released by the fission of hydrogen in 1 kilogram of element B = 1.3 times 10 Superscript 10
