Use ratio and proportion:
$29.50 is to 250 ft. as how much is to 40 ft.
29.5 / 250 = x / 40
x = 40(29.5) / 250
x = 1180 / 250
x = 4.72
40 ft. would cost $4.72
If it’s a half circle, the central angle should be 180 degrees.
Let X be width <span>of a rectangle, then
(x+8) - </span><span>length
(x+x+8)*2 = 52
x+x+8 = 52/2
2x+8 = 26
2x = 26-8
2x = 18
x = 18/2
x = 9 cm
Answer: 9 cm.</span>
1/2 gallon= .75 grams
1 gallon= 1.5 grams
2 gallons = 3 grams
4 gallons = 6 grams
So
4 gallons is 6 grams
Then we add on a half which is .75 grams
6g + 0.75g = 6.75g
Hope that helps ;•)
