Mon had 100 kg of water, dumped it into 10kg of pure salt, namely 100% salt, what happened? well, it ended up with 100kg + 10kg, or 110kg of saline solution, off which 10kg are just salt.
so, if we take the 110kg to be the 100%, what is 10kg in percentage off of it? namely the salty part.
I believe it’s B. The others didn’t seem correct.
18/20=0.9
Move decimal two spaces to the right and include percent sign
90%
May I ask what the ratio is? *Comment it below this post and i'll help you!* <3
∠DOC is the average of the given angle values,
(170° +44°)/2 = 107°
∠DOB is the supplement to that,
180° -107° = 73°
The appropriate choice is
B) 73°
