At 11:00 a. M., there are 400 members and 150 non-members visiting a museum. After 11:00 a. M., 10 members leave every five minutes and 5 non-members arrive every five minutes. What is the ratio of members to non-members at 1:00 p. M.?

Step-by-step explanation:

GIVEN: At , there are members and non-members visiting a museum. After ,   members leave every five minutes and non-members arrive every five minutes.

TO FIND: ratio of members to non-members at

SOLUTION:

Total number of members in museum at

as after every minutes members leave

total number of   minutes interval in hour

total members at    

Total number of non-members in museum at  

as after every minutes non-members arrive

total number of   minutes interval in hour

total non-members at    

ratio of members to non-members at    

Hence the ratio of members to non-members at is

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
