Well heck,   that makes sense.....hadn't thought of it that way....THANX, Melody !  

55/75 x 100% = 73.3 % Won

55/75  also equals  11/15 games won

Let x be the number

the smaller number is then x-10

Now  12 (x-10) - x  = 45

          12x - 120 - x = 45

           11x = 165

              x = 15         then the smaller number is   x-10 = 5        then the sum is   20

For an arithmetic sequence   Sn = n/2 (a1+an)

208 = 3/2(10+a3)

a3=128.66

10              a2                  128.66                (128.66+10)/2 = D  = 59.33

10        10+59.33         10 + 59.33+ 59.33

10         69.33                128.66

an then becomes       an= 10 + 59.33(n-1)          or     an = 59.33n - 49.33

Here is the graph:

There is no way to answer this unless you give us the PRICES of Kona and Plain.....

I will assume you MEANT  Force = 0.02 Newtons  and distance = 300 m   (not m/s)

Work = Force x Distance

W =  .02 (300) = 6 joules

Car                                   Truck

|--------|--------|--------x--------|

x is where they meet...car has travelled 3/4 and truck has travelled 1/4 (in the opposite direction) (because truck travels at 1/3 speed of car)

time units for car to get to x = 3         for truck to get to x is also 3

time units for car to back up to start to let truck pass = 3 x 3 = 9

time units for car to continue forward to other side = 4

Total time for both vehicles to be clear would then be   9+4= 13 time units from point x start

Time units for truck to get to x = 3

Time units for truck to back up to its origin = 3x3 = 9

Time units for truck to then cross thru detour and clear the ither end = 3x4 = 12

Total time if for both vehicles to clear if TRUCK is the one to back up = 9+12 = 21 time units

SO it is faster if the CAR backs up to the start to let the truck pass and then the car continues on its way across.

That wasn't my comment...it was a comment FROM someone TO me.....   I thought it was cool!

Using synthetic division and dividing x^3+kx^2-2x+k+4    by  x+k    results in a remainder of

3k+4     if this remainder is set to = 0    you will find   k = -4/3  will answer this question.
