Answer:

Step-by-step explanation:
3 hours is equivalent to 180 minutes (found by multiplying the number of hours, 3, by the number of minutes in an hour, 60).
Therefore, the fraction of 3 hours that 25 minutes represents is
, which can further be simplified to
.
60 mL = 60/1000 L
= 0.06 L
1 container of resin = 0.06L
19 containers of resin = 0.06 x 19
= 1.14 L
1.14 L of hardener should be added to 19 containers of resin.
44,334 SO first do (4×1×4×2×4×8)+(5×1×2×8) that's how you solve it
