Answer:
Step-by-step explanation:
- 300 × x/100 = 27
- => 3 × x = 27
- => x = 27/3
- => x = 9
<u>This means that 9% of the notebook is used in science. </u>
- 100% - 9% = Percentage of paper left in notebook.
- => 91% = Percentage of paper left in notebook.
This means that 91% of the notebook pages is remaining.
Answer:
answer is
x1= 1/2 + 1/2 * i *sqrt(5)
x2= 1/2 - 1/2 * i *sqrt(5)
Step-by-step explanation:
Please refer to the attached picture for the procedure
Keep in mind, that the first step to use the quadratic formula is to rearrange the terms.
So the best I could come up with is paper-rock-scissors; the operation takes two inputs and puts out the winner (assuming they are different).
So (paper rock) scissors= paper scissors = scissors,
But paper (rock scissors)= paper rock = paper.
This is a good example because it shows that associativity matters even outside of math.
Answer:
The answer is 12.
Step-by-step explanation:
If you divide 48 by 4 will give you 12 and it's correct because when you multiply 4 times 12 give you 48. You can also use the solution of the picture.
Answer:
Since it's a straight line, hence the sum of both angles must be 180°
now,
(2y + 1) + (5y - 3) = 180°
now by solving above equation u can get the value of y!
