For this case we must find the current height of Osian. For this, we use the following rule of three:
1.5 m ----------------> 100%
x -----------------------> 120%
From here, we clear the value of x.
We have then:

Answer:
The current height of Osian is given by:

Here's the volume formula (and the area formula) typed a little neater than that.
(I'm guessing you forgot to type in your question?)
Answer:
depends on situations
Step-by-step explanation:
Answer:
Properties in math are used as general rules to solve problems.
I hope this helped!
Step-by-step explanation:
Subtract 19 from both sides
-3x=2+x
Subtract x from both sides
-4x=2
Divide both sides by -4
x=-1/2
Final answer: x=-1/2
