Answer:
I can try
Step-by-step explanation:
Answer:
44%
Step-by-step explanation:
So you have 2 bottles. One bottle is 8ml and is 80% acid. the other is 12 ml and is 20% acid.
This means there's 6.4 ml of acid in bottle 1(8*0.8) and 2.4 ml of acid in the other one(12*0.2).
The total amount of liquid is 8+12 = 20
The total amount of acid is 6.4+2.4 = 8.8
Percentage of acid in the new solution is 8.8/20 = 0.44 = 44%
It could be 3 and lower because if you - 7 from -10 you get -17 then your equation would be -5x< -17 than you divide -17 by -5 and get 3.4 than your equation is x < 3.4 so your answer is 3.4 or below.
No of ways = 9! = 362880
The fourth option is correct.
