Answer A isn't correct, actually none of those 4 options are correct: 200 * 0.9 = 180 ml of alcohol 180 / 0.75 = 240 ml of water + alcohol 240 - 200 = 40 ml of added water To check: 240 * 0.75 = 180 ml of alcohol (correct) 💯
@Deluluuu i think i learned the "basics at 13" but im 17 now in college and im learning like the hardcore vers of it, with paranteses, exponents and radicals in one but yeah quadric equations are pretty easy but still takes so much time escpecially if you have to use zero-product property, to find the solution.
Ignore this if you hate reading long texts and personal life experience
Well I started learning stuff like this when I was 6~7, I really hated studying with my tutors all the time, resulting in me sneaking out every once in a while. I hated being a top student always studying. That's why I didn't become a top student when I was older only to be compared to my cousins who were also very smart always in the top 5 without much effort. Having Asian family really sucks when it comes to grades. But lol I'm close to all my cousins and they even help me do my homework and sometimes do everything for me (they are too kind). But still always being compared to my relatives and family who are born smart sucks. Kinda hate that almost all of my family and relatives are smart. But well everyone is close and harmonious with each other so no one hates each other.
Lol if you read this far I really appreciate it. Thank you for listening/reading my life story. But lol I'm now very happy (since giving up studying all the time and meeting real friends who are unique, they excel in different things like one is very smart, other is athletic, other is a good gamer, and so on). This you read this far you're a good listener, let's be friends even just reading friends who share good manwha's.
currently im learning quadratic equation i hate it
