Answer:16
Step-by-step explanation:
(4(10)+2(6)+3(2+2))/4=16
Step-by-step explanation:
we have 8 equally "heavy" batches.
one weighs 3.9 × 10^-10 g
so, the total sample then weighed
8 × 3.9 × 10^-10 = 31.2 × 10^-10 = 3.12 × 10^-9 g
Answer:
Average speed of the car is 60 mph
Step-by-step explanation:
300 miles divided by 5 hours will give you yours mph (miles per hour, which is also your "average speed" for this trip), So
300 / 5 = 60 mph
To take this further and find the miles per minute, you would take your mph and divide that by 60 (because there are 60 minutes in 1 hour), So
60 / 60 = 1 mile per minute
