Answer:
[2 5 0]
[-7 -11/2 12]
Step-by-step explanation:
We want to perform elementary row operation represented by R2 - ½R1 on matrix A in the figure attached.
Now, matrix A is given as;
[2 5 0]
[-6 -3 12]
Now, R1 is row 1 = [2 5 0]
R2 is row 2 = [-6 -3 12]
Thus, R2 - ½R1 = [-6 -3 12] - ½[2 5 0]
This gives;
[-6 -3 12] - [1 5/2 0] = [-7 -11/2 12]
Now,[-7 -11/2 12] will be the new row 2 since it's just an elementary row operation we did on the Matrix A.
Thus, the new matrix is now;
[2 5 0]
[-7 -11/2 12]
Answer:
Water flows through a pipe at a rate of about 502 milliliters per hour.
Step-by-step explanation:
1 Pint is equal to 473.176 Milliliter
There are 8,760 Hous in a Year
---------------------------------------------
9,300 Pints is <em>about</em> 4,400,541 Milliliters
4,400,541 divided by 8,760 is 502.344863014
Thats <em>about</em> 502 Milliliters

Hello!
Whole numbers are numbers without a decimal point, also known as an integer (ex. -4, 0, 3, 10).
Rational numbers are a number than can be turned into a simple fraction (ex. -3/1, 4/5, 1/3, 1.75)
Natural numbers are integers that are NOT negative, sometimes zero.
Therefore, the answer is A. whole numbers, integers, rational numbers.
7% of 2.99 is 2.99 ÷ 100, then multiplied by 7. 2.99 divided by 100 is 0.0299. 0.0299 is 1% of 2.99. Then multiply that (0.0299) by 7 to get 7%; 7% = $0.21. Then add that to $2.99 and you get $3.20.
Please mark as brainliest if this answer help you. I hope it did!
