So, I wanted to order my mom flowers that's going through a rough time, but her apartment is only accessible through a locked door to the main lobby. I am wondering if I send some through an online service, if the delivery man would be able to bring them to her door, or would he be suck outside and just leave the flowers outside the lobby door? I don't know her daily scedule so I don't want to risk them getting set outside and missed/stolen. Also, does anyone have a reccomendation for a good service with cheapish flowers? Thanks alot!

This is pretty ridiculous but I cant figure out how my teacher did this algebra for the life of me can anyone write it out step by step please? Thanks!

Original Equation: a = g-((I*a)/((r^2)*m))

and simplifying to solve for a she got:

a = g/ (1+(I / (r^2*m)))

So I am doing a school project comparing different properties of Craftsman screwdrivers to other brands, and they closed down our lab before I could do my hardness testing. I cannot find any information online about the specific alloy used in making Craftsman screwdrivers, or any other company's specific alloy. Does anyone know somewhere I can find any information on either the hardness or specific alloy used for tools like these? Doesn't have to be Craftsman, I just need a baseline.
