Answer:
<u>Amanda can make 1.5 or 3/2 of batches of pancakes with 11/22 of a cup of milk.</u>
Step-by-step explanation:
1. Let's review the information given to us for answering the question correctly:
Amount of milk Amanda use for a batch of pancakes = 1/3 cup
2. How many batches can she make if she only has 11/22 of a cup of milk left?
Let's simplify 11/22, dividing by 11 the numerator and the denominator,
11/22 = 1/2
Now, using the Rule of Three Simple, we can calculate the answer to this question, this way:
Number of batches = (1/2 * 1)/1/3
Number of batches = 1/2 / 1/3
Number of batches = 1/2 * 3/1 (Taking the reciprocal)
Number of batches = 3/2 = 1.5
<u>Amanda can make 1.5 or 3/2 of batches of pancakes with 11/22 of a cup of milk.</u>
The top row of matrix A (1, 2, 1) is multiplied with the first column of matrix B (1,0,-1) and the result is 1x1 + 2x0 + 1x -1 = 0 this is row 1 column 1 of the resultant matrix
The top row of matrix A (1,2,1) is multiplied with the second column of matrix B (-1, -1, 1) and the result is 1 x-1 + 2 x -1 + 1 x 1 = -2 , this is row 1 column 2 of the resultant matrix
Repeat with the second row of matrix A (-1,-1.-2) x (1,0,-1) = 1 this is row 2 column 1 of the resultant matrix, multiply the second row of A (-1,-1,-2) x (-1,-1,1) = 0, this is row 2 column 2 of the resultant
Repeat with the third row of matrix A( -1,1,-2) x (1,0, -1) = 1, this is row 3 column 1 of the resultant
the third row of A (-1,1,-2) x( -1,-1,1) = -2, this is row 3 column 2 of the resultant matrix
Matrix AB ( 0,-2/1,0/1,-2)
