Answer: The mass of solid a is 4800 grams
Step-by-step explanation:
Hi, to answer this question we have to apply proportions:
For solid b = 40.32 cm2 / 6912 grams
For solid a = 28 cm2 / x grams
Where x is the mass of solid a.
So:
40.32 / 6912 = 28 / x
x = 28 / (40.32 / 6912)
x = 4800 grams
The mass of a is 4800 grams
Feel free to ask for more if needed or if you did not understand something.
1 m = 100 cm
Multiply:
100 * 400 = 40000
So she ran 40,000 centimeters.

Answer:
y-determinant = 2
Step-by-step explanation:
Given the following system of equation:
Let's represent it using a matrix:
![\left[\begin{array}{ccc}1&2\\1&-3\end{array}\right] = \left[\begin{array}{ccc}5\\7\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%262%5C%5C1%26-3%5Cend%7Barray%7D%5Cright%5D%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D5%5C%5C7%5Cend%7Barray%7D%5Cright%5D)
The y‐numerator determinant is formed by taking the constant terms from the system and placing them in the y‐coefficient positions and retaining the x‐coefficients. Then:
![\left[\begin{array}{ccc}1&5\\1&7\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%265%5C%5C1%267%5Cend%7Barray%7D%5Cright%5D%20)
y-determinant = (1)(7) - (5)(1) = 2.
Therefore, the y-determinant = 2
