Okay but I don’t know need the points for thib
Basic trig concepts you have to keep in mind:
SOH CAH TOA
Sine: Opposite of the angle over the hypotenuse
Cosine: Adjacent over hypotenuse
Tangent: Opposite over adjacent
I'll do one of the problems, you should be able to do the rest (It's good practice ;))
Answer:
you multiply both sides of the equation by x
you divide both sides of the equation by (2.5) to get x
47.2 is 40% of 118
Step-by-step explanation:
Answer:
42% acid
Step-by-step explanation:
Suppose that these two storage containers are filled to complete capacity?
That makes the second container have 3 volume parts and the first container having 2 volume parts.
v*(1.50)= (3/2)*v
First Container 2v 30% acid
Second Container 3v 50% acid
The mixture of all of this is in the third container. Two parts plus three parts is 5 parts for the mix volume.
=(2*30+3*50)/5
=210/5
=42
So,
42 % Acid, mixture
