Can someone do this for me? ? i don’t understand all of it

I’m pretty sure the answers are:

250 meters=0.25 kilometers

12 meters=0.012 kilometers

1 meter=0.001

5 kilometers=5,000 meters

20 kilometers=20,000 meters

0.3 kilometers=300 meters

For future reference, you can find the constant of proportionality by dividing the x value by the y value. Then you multiply each given number by the constant of proportionality, and that’ll give you your answers.

Unfortunately, I don’t know the answers to the last few questions. Sorry about that!

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
