Answer:
24%
Step-by-step explanation:
t = ???
P = 2,200
I = 528
r = 12%
528 = 2,200(t x 1)
t = 528/2,200
t = 0.24
t = 0.24 x 100 = 24%
The MN matrix is ![\left[\begin{array}{ccc}-2 & 1 & 0 \\17 & 2 & -3\\11 & 12 & -5\end{array}\right]\\](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-2%20%26%201%20%26%200%20%5C%5C17%20%26%202%20%26%20-3%5C%5C11%20%26%2012%20%26%20-5%5Cend%7Barray%7D%5Cright%5D%5C%5C)

What is matrix?
A matrix is a rectangular array or table with rows and columns of numbers, symbols, or expressions that is used to represent a mathematical object or an attribute of one. is a matrix having two rows and three columns, for instance.
Given ![M=\left[\begin{array}{cc} 1 & 0 \\ -4 & 3 \\ 2 & 5 \end{array}\right]](https://tex.z-dn.net/?f=M%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D%201%20%26%200%20%5C%5C%20-4%20%26%203%20%5C%5C%202%20%26%205%20%5Cend%7Barray%7D%5Cright%5D)
![N=\left[\begin{array}{ccc}-2 & 1 & 0 \\3 & 2 & -1\end{array}\right]](https://tex.z-dn.net/?f=N%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-2%20%26%201%20%26%200%20%5C%5C3%20%26%202%20%26%20-1%5Cend%7Barray%7D%5Cright%5D)
M is a matrix with 3 * 2 dimension and N is a matrix with 2 * 3 dimension.
So finding MN is possible and the dimension will be 3 * 3.
Now,
![MN=\left[\begin{array}{cc}1 & 0 \\-4 & 3 \\2 & 5\end{array}\right] \times \left[\begin{array}{ccc}-2 & 1 & 0 \\3 & 2 & -1\end{array}\right]\\= \left[\begin{array}{ccc}1 \times (-2)+0 \times 3 & 1 \times 1+0 \times 2 & 1 \times 0+0 \times (-1) \\(-2) \times (-4)+3 \times 3 & (-4) \times 1+3 \times 2 & (-4) \times 0+3 \times (-1) \\2 \times (-2)+5 \times 3 & 2 \times 1+5 \times 2 & 2 \times 0+5 \times (-1) \\\end{array}\right]\\](https://tex.z-dn.net/?f=MN%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D1%20%26%200%20%5C%5C-4%20%26%203%20%5C%5C2%20%26%205%5Cend%7Barray%7D%5Cright%5D%20%5Ctimes%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-2%20%26%201%20%26%200%20%5C%5C3%20%26%202%20%26%20-1%5Cend%7Barray%7D%5Cright%5D%5C%5C%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%20%5Ctimes%20%28-2%29%2B0%20%5Ctimes%203%20%26%201%20%5Ctimes%201%2B0%20%5Ctimes%202%20%26%201%20%5Ctimes%200%2B0%20%5Ctimes%20%28-1%29%20%5C%5C%28-2%29%20%5Ctimes%20%28-4%29%2B3%20%5Ctimes%203%20%26%20%28-4%29%20%5Ctimes%201%2B3%20%5Ctimes%202%20%26%20%28-4%29%20%5Ctimes%200%2B3%20%5Ctimes%20%28-1%29%20%5C%5C2%20%5Ctimes%20%28-2%29%2B5%20%5Ctimes%203%20%26%202%20%5Ctimes%201%2B5%20%5Ctimes%202%20%26%202%20%5Ctimes%200%2B5%20%5Ctimes%20%28-1%29%20%5C%5C%5Cend%7Barray%7D%5Cright%5D%5C%5C)

Answer:
n=9
Step-by-step explanation:
21/35 has a gcf of 7. so reduce to 3/5
move 3/5 to the left side to get
n/15=-3/5=0
solve as a linear equation.
n/15=-3/5=0 is equivalent to .67*n-0.6=0
which is equal to n=-9
Answer:
Arranging the numbers in increasing order is 14.200, 14.204, 14.210, 14.240.
Step-by-step explanation:
Given : Numbers 14.204, 14.200, 14.240, 14.210.
To find : Arrange the numbers in increasing order ?
Solution :
Arrange the numbers in increasing order is defined as arranging numbers from the smallest number to the largest number.
If we see the numbers 14.204, 14.200, 14.240, 14.210.
The number before decimal is same so we arrange according to after decimal,
14.200<14.204<14.210<14.240
Therefore, Arranging the numbers in increasing order is 14.200, 14.204, 14.210, 14.240.
