City M is 600 km from City N. A bus drives 60 km/h and a truck drives 50 km/h along the road between City Mand City N. How
long after the truck should the bus start driving if they want to
meet in the midpoint of the road?

After  2h  s

Step-by-step explanation:

The  the  whole  journey  is  600  km  from  city  M  to  N.  So  the  mid  point  would  be  300  km

The  bus  takes  5  h  to  reach  the  mid point  of  the  road  (  300  km  ÷ 60  km/h  =  5  h)

And  the  truck  takes  6  h  to  reach  the  mid  point  of  the  road  (  300 km  ÷  50  km/h  =  6  h)

So  if  they  want  to  meet  each  other  the  bus  should  start  its  journey    one  hour  after  the  truck.

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
