What percentage would my grade be if I got a 50% on a project that is worth 20% of my grade and my grade is 87%/B+. How much would my grade go down?

If you got 52% then you would drop to an 80 i’m pretty sure

It depends on what type of third separates the three notes.for example: if you have two mayor thirds is an "aumented chord"if you have two minor thirds is an "diminued chord"if you have one mayor first and then one minor is a "mayor chord"and inverted is a "minor chord"

Ithink he answer is prolly a
