Answer:
=6/7x^3
Step-by-step explanation:
36x^4/42x^7
(36/42)(x^4/x^7)
6/7(x^-3)
6(x^-3)/7
6/7x^3
Distance = Speed x time
45 minutes = 45/60 = 0.75 hours
Total time = 3.75 hours
Distance = 80 km/hr x 3.75 hours
Distance = 300 km
Answer: 300 km
Answer: Look at explanation for answer...
Step-by-step explanation:
This could be turned into a simple proportion if you want to do it that way :)
1.) First, use the proportion bacteria over time.
2.) It should set up to look like this: 2,600 X
---------- = ---------
7 15
3.) You then do your math (2,600 * 15) (39,000 / 7)
Answer: Your answer then comes out to be: (rounded) 5,571 bacteria
Answer:
The diver’s depth is 18.5 feet below from sea level.
Given that, A diver begins at sea level and dives down 200 feet.
He ascends at a steady rate of 121/3 feet per minute for 4.5 minutes.
This depth is represented by the numerical expression is,
Negative sign indicate that below the sea level.
Hence, The diver’s depth is 18.5 feet below from sea level.
