Roll ends of carpet are on sale for six dollars per square yard. To finish the rough-cut edges, edging material costing 10 cents per foot is glued in place. Compute the total cost of a roll end measuring 9 feet by 10 feet.

Total cost the roll end is $63.8

Step-by-step explanation:

Since dimensions of the roll ends = 9 feet × 10 feet

By converting these dimensions in yards = yards [Since 1 feet = yards]

Area of the roll ends = = 10 square yards

Cost of the roll ends = $6 per square yards

So cost of these roll ends = 10×6 = $60

To finish the rough-cut edges, edging material costs = $0.10 per feet

Total length to be glued = Perimeter of the carpet

= 2(length + width)

= 2(9 + 10)

= $38

Total cost to glue the edging material = 38×($0.10) = $3.8

Now total cost of the roll end = $60 + $3.8

= $63.8

Therefore, total cost of a roll end = $63.8

im alright what do you need

step-by-step explanation:

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
