Se realizó una serie de experimentos pasando 40 °c de aire sobre un cilindro largo de 25 mm de diámetro con una incrustación calentador eléctrico. el objetivo de estos experimentos era determinar la potencia por unidad de longitud requerida (w · / l) a mantener la temperatura de la superficie del cilindro a 300 °c durante diferentes velocidades del aire (v). los resultados de estos experimentos. se dan en la siguiente tabla:

it is probably the graph on the bottom right.

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.

step-by-step explanation:

yes, i think so although i am not sure. this is a very strange question.
