44 days ago, Emily blew up a balloon (that is a perfect sphere) to a radius of 5\text{ cm}5 cm5, start text, space, c, m, end text. Since then, the balloon has lost air and decreased by 0.5\text{ cm}0.5 cm0, point, 5, start text, space, c, m, end text each day.
What is the ratio of the current volume of the balloon to the volume of the balloon 444 days ago?

c

step-by-step explanation:

i think because what else can be a sample of every member

i dont know

step-by-step explanation:

umm. i dont know

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.

d. all of the above
