9,660/0.5m3=19.320kg/m^3
Get it from this equation m=pV
p is density ,V volume, m mass
Hope it helps ;)
Your answer would be 312.50. you would first subtract 125,000 and 12,500 and that equals 112500. you than divide that from 360 and than you get 312.50.
Answer: (c)
Step-by-step explanation:
In the given figure, two triangles are similar namely 
and 
For similar triangles, the ratio of the corresponding sides are equal.
For option (a), Hypotenuse to Perpendicular ratio is given, that is correct
Similarly for option (b), Perpendicular to hypotenuse ratio is given
Both option (a) and (b) gives the same value of 
that is,
Option (c) does not give the correct value of
Answer:
No solution
Step-by-step explanation:
A solution for a system of equations entails that all variables are the same. In this case, it means that both x and y must be the same.
Looking at the graph, there is no spot where y=3x+3 and 3x-y=2 intersect
To confirm, we can look at the equations. If we make them both equal to y, we can set them equal to each other.
For y=3x+3, this is already set to y. For 3x-y=2, we can add y to both sides and subtract 2 from both sides to get
3x-2=y
3x+3=y
Since the x and y values must be the same, we can say that
3x-2=3x+3
subtract 3x from both sides
-2 = 3
Since -2 is not equal to 3, we can confirm that there are no solutions to this system of equations
Answer:
Answer B: -30
Step-by-step explanation:
Let B be as follows:
[-18 3]
[4 1 ]
To find the determinant, multiply diagonally <em>downward</em> from -18 through 1, obtaining -18. We keep this sign as is.
Continue: Start at 4 and move diagonally <em>upward</em> through 3; this product is 12. Because we moved upward, give this result the opposite sign: -12.
Now add together these two products; that is, add together -18 and -12. Here the sum is -30. This is the determinant of the matrix. It's Answer B.
Finding the determinant of a 3x3 matrix obviously requires more steps, but the general approach is similar.
