Answer:
The ratio of how much they have watched to how much they have left to see is 4 : 1.
Step-by-step explanation:
Consider that the total duration of the film is, 1.
It is provided that James and Cameron paused when there is one-fifth left to watch.
That is, they have already watched,
th of the film.
Compute the ratio of how much they have watched to how much they have left to see as follows:

Thus, the ratio of how much they have watched to how much they have left to see is 4 : 1.
Answer:

Step-by-step explanation:
Let's call y the number of patients treated each week
Let's call x the week number.
If the reduction in the number of patients each week is linear then the equation that models this situation will have the following form:

Where m is the slope of the equation and b is the intercept with the x-axis.
If we know two points on the line then we can find the values of m and b.
We know that During week 5 of flu season, the clinic saw 90 patients, then we have the point:
(5, 90)
We know that In week 10 of flu season, the clinic saw 60 patients, then we have the point:
(10, 60).
Then we can find m and b using the followings formulas:
and 
In this case:
and 
Then:


And


Finally the function that shows the number of patients seen each week at the clinic is:

Answer: 60
Step-by-step explanation:
75% of 80 is 60.
Multiply 80 by .75 to get the answer.
306+122=428
Because you add 6 & 2 in the ones place which is 8.
then 2 and 0 which is 2.
finally 1 and 3 which is 4
