Given
Juli has 200 ml of 35% hand sanitizer
Sarah has 150 ml of 85% hand sanitizer
The mixture has 60% con. i.e. 60 % is Alcohol and 40 % water
The final volume of the mixture =200+150=350 ml

Answer:the side length of a square with the area 0.09 square meter is 0.3 meter.
Step-by-step explanation:
The side length of a square S can be determined by the formula S equals the square root of a where a represents the area of the square. It means that
S = √a
Therefore, the side length of a square with the area 0.09 square meter would be
S = √0.09 = 0.3 meter
The answer is The equation 3.5|6x – 2| = 3.5 has one solution
Answer:
38.5
Step-by-step explanation:
Lets say, first number = x
Second number = 3x+7
Total = 49
(x)+(3x+7)= 49
4x+7 = 49
4x = 42
x = 42/4
x= 10.5
x= 10.5
3x+7 = 3(10.5)+7 = 38.5
Hope this helps!!
