Answer:
BC would be 8.
Step-by-step explanation:
40 x 0.2 = 8
(Try graphing on a number line)
Just use y=Mx+b format. First point is at (0,0) then next is at (1,8) because the slope is 8/1.
The bacteria at the end of 22 hours is 2,480
2L+2W=157.5
L=W-30
2(W-30)+2W=157.5
2W-60+2W=157.5
+60 +60
4w=217.5
W=54.4(.37 rounded to nearest tenth)
L=24.4
