Cole has 8 pieces of string that are 5 yards each. he uses 4 pieces that are each 5 feet long. how many feet of string does cole have left?

Remember that 1 yard = 3 feet. So if Cole has string that is 5 yards each, each string should be 15 feet long (5 x 3). Since each string is 15 feet long and Cole has 8 strings, Cole should have 120 feet of string (15 x 8). 

Cole now uses 4 pieces that are each 5 feet long, so 4 x 5 = 20 feet used.

What's 120 - 20? That should give you your answer. 

Answer:

$4034.40

step-by-step explanation:

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
