Answer:
Displacement versus time is velocity
Step-by-step explanation:
Displacement versus time is velocity
Acceleration is change in velocity over time
Speed is distance over time
Momentum is mass times velocity
This rule is known as PEMDAS
In an algebraic equation follow PEMDAS
P= first calculate anything with parantheses
E= then calculate anything with exponents
M= calculate any multiplication
D= calculate any division
A= calculate any addition
S= calculate any subtraction
you must do these in that order
hope this helps:)
Answer:
20, 000
Step-by-step explanation:
For a duration of 50 years, the consumption will be equal to the product of annual consumption and the number of years hence 800*50=40, 000 barrels.
Since 20, 000 barrels are unknown and they are part if consumption in the next 50 years, then the known or proven reserves will be given by getting the difference between total consumption and unknown reserve, expressed as 40, 000-20, 000=20, 000 barrels.
Let the number be x.
2*(x-4) < (x+5).
2x -8 < x +5
2x-x < 5 +8
x<13.
The number is less than 13.
That's it. Cheers.
