Answer:
1. =2
2. times 2
3. b.
Step-by-step explanation:
The first one- the rest don’t add up
The solution is 40% acetic acid.
Multiply the amount of the solution by 40%:
15 liters x 0.40 = 6 liters
There is 6 liters of acetic acid
Tan[theta] = Opposite/Adjacent
Tan[theta] = 56/42
[theta] = Tan^-1 56/42
[theta] = Tan^-1 1.333
[theta] = 53.130
But unless your teacher specified, you can use any of the SOH CAH TOA methods for this.
Answer:
x = -36
Step-by-step explanation:
Add 12 to both sides
x - 12 + 12 = x
(12 cancels out)
-48 + 12 = -36
x = -36
