5L:25Seconds=1L:5seconds
In 50 seconds there will be 10L of water
In 45 We will have to subtract 1L because we are exceeding 5 seconds and in 5 seconds 1L of water comes out
10L-1L=9L
There will be 9L of water
Answer:

The value of S(50) is 22 in means the amount of sodium iodine in the mixture is 22 when 50 milliliters of the 20% solution used.
Step-by-step explanation:
It is given that a chemist working on a flu vaccine needs to mix a 20% sodium-iodine with a 60% sodium-iodine to obtain a 70-milliliter mixture.
Let x be the number of milliliters of the 20% sodium-iodine.
Number of milliliters of the 60% sodium-iodine = 70-x
The amount of sodium iodine in the mixture is 20% of x and 60% of (70-x).



Therefore,the required function is
.
Substitute x=50 in the above equation.


The value of S(50) is 22 in means the amount of sodium iodine in the mixture is 22 when 50 milliliters of the 20% solution used.
Answer:
j would be 130 cuz sides that are congruent have congruent angles so you add those two angles up and subtract from 180
Answer:
x = -4
Step-by-step explanation:
-18 = 6+6x
-18 -6 = 6x
-24 = 6x
-24/6 = x
x = -4
Checking Part:
-18 = 6 + 6x
-18 = 6 + 6(-4)
-18 = 6 -24
-18 = -18
Answer:
Step-by-step explanation:
2000≤20x +475
x = 76.25 so 76 people may attend
graph a number line from 0 to 76 . include the end points
1) no more 76 may attend
2)less than 77 may attend
3) between 0 and 76 may attend
