<span>it will take 24 gallons in 18 seconds to travel 1 mile</span>
The question here is how long does it take for a falling
person to reach the 90% of this terminal velocity. The computation is:
The terminal velocity vt fulfills v'=0. Therefore vt=g/c,
and so c=g/vt = 10/(100*1000/3600) = 36,000/100,000... /s. Incorporating the
differential equation shows that the time needed to reach velocity v is
t= ln [g / (g-c*v)] / c.
With v=.9 vt =.9 g/c,
t = ln [10] /c = 6.4 sec.
Answer:
Sally has been measuring the tree for 4 months
Step-by-step explanation:
The correct question is as follows;
Sally has been measuring the tree in her yard for a science project. The tree has grown 1/2 of an inch each month and grown a total of 2 inches taller. How many months has Sally been measuring this tree?
.........................................................................................
Solution;
The tree has grown 1/2 of an inch each month and has grown a total of 2 inch taller.
We now need to know the number of months in which the measuring has been taking place.
To know the number of months, we simply need to divide the change in height which is 2 inch by the individual month growth rate which is 1/2 inch
So mathematically, that would be 2/1/2 = 2 * 2 = 4 months
Answer:
(the second option)
Step-by-step explanation:
Hope this helps!
Answer:
Step-by-step explanation:
5y + 6y + 7y = 18y......any numbers that add(or subtract) to equal 18, stick them before the y....
or it could be : 10y + 10y - 2y = 18y or 5y + 10y + 3y or 30y - 20y + 8y....I could go on forever...lol
