We know that the variation is proportianal, that is we can relate the quantities as:
where y is the mass of the body and x is the mass of water. From the values given we have that:
hence the constant of proportionality is 3/2. Now, if the mass of the water is 75, then the mass of the body is:
Therefore, the mass of the body is 112.5 kilograms
Answer:
B) no solution
Step-by-step explanation:
this can be solved by substitution method
y= ⅔x + 4. (equation 1)
and 2x-3y= 3. (equation 2)
substitute for y into equation 2
2x-3(2/3x + 4) = 3
2x - 2x -12=3
0=15
this is a no solution equation
Answer:
427 units square
Step-by-step explanation:
Answer:
-3n⁹
Step-by-step explanation:
= ![\sqrt[3]{-27n^(27)}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B-27n%5E%2827%29%7D)
= ![\sqrt[3]{-27} * \sqrt[3]{n^{27}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B-27%7D%20%2A%20%5Csqrt%5B3%5D%7Bn%5E%7B27%7D%7D)
= (-3) × n⁹
= -3n⁹
