Asap 10 points (if possible show work so i understand)
1. the formula v = ir shows the relationship between voltage, current, and resistance.  solve this formula for r. 
2. bonnie has a container in the shape of a rectangular pyramid. the formula for the surface area of the enclosed space is s = lw + 0.5ph.  solve for p.
3. the formula i = prt where i = interest, p = principal, r = rate, and t = time is used to calculate the amount of simple interest earned.  solve this formula for t.
