Answer:
length = 235 yd
width = 58 yd
Step-by-step explanation:
Let the width be W.
L = 4W + 3
perimeter = 2(L + W)
perimeter = 2(4W + 3 + W)
perimeter = 2(5W + 3) = 10W + 6
We are told the perimeter = 586 yd
10W + 6 = 586
10W = 580
W = 58
L = 4W + 3 = 4(58) + 3 = 232 + 3 = 235
length = 235 yd
width = 58 yd
2x+4x+9x=180 15x=180 180/15=12 substitute x for 12 to find the angles
If a total of 780 joules of energy is lost by 25.0 grams of this substance, the heat of fusion is 31.2 J/g
The energy lost, H = 780 Joules
Mass of the substance, m = 25.0 grams
The Energy lost is the product of mass and the heat of fusion
The heat of fusion, c, is calculated using the equation below:
H = mc
Substitute H = 780 Joules and m = 25.0 grams into the equation
H = mc
780 = 25c
Divide both sides by 25

The heat of fusion of the substance is 31.2 J/g
