First, we have to make sure that the number of columns in the first matrix is equal to the number of rows in the second matrix.
Since this is true, we can continue to solve the problem.
To multiply two matrices, multiply each row element in the first matrix by each column element in the second matrix. For example:
1*2 = 2
-3*1=-3
Then we add them to get our new matrix element.
-3+2=
-1Then we move to the next column of the second matrix.
1*3=3
-3*2=-6
-6+3=
-3Then the final column of the second matrix.
1*4=4
-3*3=-9
-9+4=-5
Our matrix so far:
We do the same for the bottom row of the first matrix.
<em>First Column</em>
2*2=4
0*1=0
4+0=
4<em>Second Column
</em>2*3=6
0*2=0
6+0=
6
<em>Third Column</em>
2*4=8
0*3=0
8+0=
8Our final matrix is:

Answer:
This can vary. Are we doing 4 letter words, 5 letter, etc?

Option B
The thickness of each washer is 0.083 inches
<em><u>Solution:</u></em>
Given that Bryce buys 9 bolts and he buys 9 washers to place onto the bolts
He puts the washers he bought in a stack that has a height of 0.747 inches
To find: thickness of each washer
From given information,
Number of washers bought = 9
Height of stack = 0.747 inches
Thus, thickness of each washer can be found by dividing height of stack by number of washers bought
Substituting the values we get,
Thus thickness of each washer is 0.083 inches
Answer:
4 layers with <u><em>$2.84</em></u><em> </em>left over
Step-by-step explanation:
You start off with the cost of the cake which is <em>$12.96</em>, then add<em> $3.55</em> (in this case 4 times) until you get the closest number to <em>$30</em> without going over (<em>$27.16</em>) . You find the amount of money that is left over by subtracting you original amount <em>($30)</em> with the amount you spent total on the cake <em>($27.16) .</em>
