The length of a string is L inches. Samantha cuts it into two unequal pieces such that the length of the small piece is 35% of L
skelet666 [1.2K]

Answer:

The shorter piece   x  =  8.4 in

The longer one    y  =  15.6 in

Step-by-step explanation:

If we cut  a string length  L  in to unequal  pieces we get two pieces

first one with length  x  and the other one with length  y

Let call  x  the smaller piece,  then   y = L  -  x will be the longer one

If   x  =  35 %    then

x  =  0,35* L     and

y = L -  x  =  L - 0,35*L      ⇒  y  =  0,65 L     ⇒ y  =  0.65*24

Now if L  =  24  in

x  =  0,35*24          ⇒               x = 8.4 in

and

L  -  x  =  0.65*L      ⇒       L - x  =  0.65*24     y  =  L  -  x  =  15.6 in

as way of verification you can add the length of the two pieces and find:

8.4  +  15.6  = 24 in

There is a field sized 6x6. Starting with cell 1:1 you must get to cell 6:6 laying the path through every cell. You are allowed
Lera25 [3.4K]
Sorry, the given solution is not valid, and unfortunately external links are not allowed, so it will be deleted.
I do not think that it is possible to visit every cell without revisiting any to go from one corner to the opposite one.
