Answer:
Please see the answer below:
Step-by-step explanation:
1
Original Price = p
Discount = 80% = 0.80
Discounted Price = 320
2
0.80p = 320
Divide the equation by 0.80, we get:
p = 400
Answer:
$1.500
Step-by-step explanation:
We use multiplying to solve this problem
Hourly payment : $15
Hours working per week : 25
weeks in a month : 4
$15 × 25 = $375 a week
4 × $375 = $1.500 a month
Endocytosis and exocytosis are the processes by which cells move materials into or out of the cell that are too large to directly pass through the lipid bilayer of the cell membrane
I would assume the order of the 3×3 matrix to be in this manner:
1 4 4
5 2 2
1 5 5
To determine the determinant of the matrix, you must multiply the number diagonally. For a 3×3 matrix, you must also form 3 diagonals up and 3 diagonals down. To do this, you copy the the first two columns and place it next to the third column.
1 4 4 1 4
5 2 2 5 2
1 5 5 1 5
The sum of the products of the diagonals down is subtracted to the sum of the products of the diagonals up. In other words,
Determinant = ∑(products of diagonal down) - ∑(products of diagonal up)
Determinant = [(1*2*5)+(4*2*1)+(4*5*5)]-[(1*2*4)+(5*2*1)+(5*5*4)]
Determinant = 0
The determinant of the matrix is zero.
