I = prt
420 = 7000 x .02 x t
420 = 140 x t
420/140 = 140 x t /140
t = 3 years
Ohio = 45,000, Cali = 160000, Texas = 270000, Connecticut = 5500, SC = 32000,
A would be true
B would be false
C would be false
D would be true, assuming "about" means you can round up a little.
hope this helped
The plane PRS passes through the points P, R and S. So it contains the line RS. Also the plane QRS passes through the points Q, R and S. So it contains the line RS as well. Since both the planes contain the line RS, the line RS must be the intersection of plane PRS and QRS
