Answer: He made 110 kilograms of 9.09% salt solution.
Step-by-step explanation:
Given: Mass of water= 100 kg
Mass of salt= 10 kg
Total mass of the solution: 100kg+10kg= 110 kg
The percent of salt in solution=![\frac{\text{Mass of salt}}{\text{Mass of the solution}}\times100](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BMass%20of%20salt%7D%7D%7B%5Ctext%7BMass%20of%20the%20solution%7D%7D%5Ctimes100)
∴The percent of salt in solution![=\frac{10}{110}\times100=9.09\%](https://tex.z-dn.net/?f=%3D%5Cfrac%7B10%7D%7B110%7D%5Ctimes100%3D9.09%5C%25)
Therefore, He made 110 kilograms of 9.09% salt solution.
Answer: 1260 books
Step-by-step explanation:
2/5=0.4
19000x0.4=7600
12500x0.4=5000
7600+5000=12600
1/10=0.1
12600x0.1 = 1260
Answer:
6!
The answer would be 6 when it comes to these types of math problems.
The sum is -20 have a great day
A = (9,-8) B = (-6,7)
P is (2/3) the line of the line segment from A to B
So, AP = (2/3) AB and BP = (1/3) AB
OR we will divide the length of AB with the ratio 2 : 1 from A
![x= ( \frac{m}{m+n}) ( x_{2} - x_{1}) + x_{1}](https://tex.z-dn.net/?f=x%3D%20%28%20%5Cfrac%7Bm%7D%7Bm%2Bn%7D%29%20%28%20x_%7B2%7D%20-%20x_%7B1%7D%29%20%2B%20x_%7B1%7D%20)
![y= ( \frac{m}{m+n}) ( y_{2} - y_{1}) + y_{1}](https://tex.z-dn.net/?f=y%3D%20%28%20%5Cfrac%7Bm%7D%7Bm%2Bn%7D%29%20%28%20y_%7B2%7D%20-%20y_%7B1%7D%29%20%2B%20y_%7B1%7D%20)
∴ m = 2 , n = 1
∴
∴
The coordinates of point P is ( -1 , 2 )
The correct answer is option three
