Which scores should i send (UMiami, UMich, UNC, Georgia tech)

Hi
I took ACT, SAT and two subject tests I am unsure which scores to send

ACT: 34 composite( superscore doesnt help me) Writing- 8/11
SAT: 1450 (superscore) Writing- 18/24(all 6’s)
Subject Tests: Bio-M-660 Math 2- 770

Should i send my ACT or SAT?
Also Should I send one, both, or none of my subject tests because none of the schools I am applying to require subject tests?

I am interested in Biomedical Engineering and business

Thanks

Act is much higher
