53.35/11 = 4.85 for 1 key chain
4.85 *4 = 19.40
What is the given matrix?
you didn't show a matrix.
the components of the matrix are the elements.
and the elements of the inverse matrix are the elements of the inverse matrix
1)
so if matrix A is 1 4 1
2 5 2
3 6 3
2)
14114
25225
36336
3)
15 24 12
15 12 24
4)
[A]=(15+24+12=51)-(15+12+24=51)
[A]=0
5)
52 23 25
63 23 36
41 11 14
63 33 36
41 12 14
52 12 25
6)
15-12 6-6 12-15
12-6 3-3 6-12
8-5 2-2 5-8
7)
3 0 -3
6 0 -6
3 0 -3
8)
(+)3 (-)0 (+)-3
(-)6 (+)0 (-)-6
(+)3 (-)0 (+)-3
=
3 0 -3
-6 0 6
3 0 -3
9)
3 -6 3
N= 0 0 0
-3 6 -3
10) the inverse of [A]= 1/|A|*[N]
which is in this case ⁻A= 0
because |A|=0
Its true because scalene doesn't have equal sides
Answer:
Step-by-step explanation:
For this exercise it is important to remember that "Times as great as" indicates multiplication.
Therefore, "4 times as great as" can be expressed as following:
So, the statement "24 is 4 times as great as" indicates that 24 is equal to .
Knowing this, you can write the following equation:
In order to solve for "k", you can divide both sides of the equation by 4. Then, you get the following result:
Answer:
vertical angles
Step-by-step explanation:
<em>Vertical angles</em> are found where lines cross, so meet the requirements of this description. They share a vertex, but not a side. The sides of one of a pair of vertical angles are rays opposite the rays that make up the sides of the other vertical angle in the pair.
