A diver ascended 8/9 of a meter in 1/9 of a minute. What was the divers rate of ascent in meters per minute?
1 answer:
The ration between the ascent and time is 8/9 is to 1/9. To get the rate per minute, your aim is to get an equal ratio using a full minute. A full minute would be 9/9. Now how do we get 9//9, you multiply 1/9 by 9.
Now to get an equal ration, you need to multiply the ascent by the same factor. So you would multiply 8/9 by 9 as well.
So the rate would be 8 meters per minute.
Now to get an equal ration, you need to multiply the ascent by the same factor. So you would multiply 8/9 by 9 as well.
So the rate would be 8 meters per minute.

Answer: The equation would be W = 500 + 30T
Step-by-step explanation: The variables given are, W which represents the amount of water, and T which represents the time in minutes that water has been added. Already there is 500 liters in the water tank to start with, that means as you begin to add water, its simply an addition to the already existing 500 liters, (that is + 500).
Also you are told that you can add water at a rate of 30 liters per minute, that is you have one T for every 30 (or simply put 30T).
Therefore the equation that correctly relates W to T is shown as;
W = 30T + 500
With this, your table of values would now be shown as;
x = 1, y =530
x= 2, y = 560
x = 3, y = 590
x = 4, y = 620
x = 5, y= 650
Then your graph is as shown in the image attached.
