No. The answer on the right is positive 16 while the answer on the left is negative 9. 16≠-9
Step-by-step explanation:
The first solution contributes 0.78*1 = 0.78 L of acid.
The second contributes 0.64*6 = 3.84 L of acid.
There will be 7 L total of the new solution, and 3.84 + 0.78 = 4.62 total L of acid in it. So the new solution has a concentration of 4.62/7 = 0.66, or about 66%.
Answer:
696 students.
Step-by-step explanation:
From the sample of students 58/125 of them like milk.
So we can predict that 1500 * 58/125 of the 1500 students like milk.
This comes to (1500/125) * 58
= 12 * 58
= 696.
