Answer:
Step-by-step explanation:
In 5 liters, there is 4% salt.
Lets find liters of salt.
First, converting 4% to decimal (dividing by 100):
4% = 4/100 = 0.04
0.04 * 5 = 0.2
So, there is 0.2 liters of salt.
Now, x liters of water is added to total, so total is now:
5 + x
The concentration of salt will be amount of salt divided by amount of salt water solution.
Amount of salt = 0.2 (as seen above)
Amount of new salt water solution = x + 5
So,
Concentration of salt in new solution is 
2nd choice is right.
Answer:
x³ - 6x² + 18x - 10
Step-by-step explanation:
(f - g)(x) = f(x) - g(x)
= x³ - 2x² + 12x - 6 - (4x² - 6x + 4)
= x³ - 2x² + 12x - 6 - 4x² + 6x - 4 ← collect like terms
= x³ - 6x² + 18x - 10
Answer:
(This is a example since you don’t have anything to round to)
Example Answer if the radius is 4 - 50.24
Step-by-step explanation:
Example Radius : 4
Area : 3.14
We have the mulitiply 3.14 times The Example Radius 2 times because The diameter of a circle is 2 times its radius.
( 3.14 x 4 x 4) 50.24
If you know the diameter, it’s a half or 1/2 as large.
Therefore, if the radius was 4, it would be 50.24.
Youre welcome :)
Answer:
im not 100% sure but i think its 9.375
Step-by-step explanation:
6x-9=15
6x=24
x=4
Therefore the answer is A.
Hope this helps :)
