the new sign for a local business contains two different sections. one of the sections will be
produced from wood, while the other will be metal metal is three times as expensive as wood.
the cost of metal needed for each sign is proportional to the diameter of the sign, while the cost
of wood needed is proportional to the square of the diameter. if the diameter of the sign is
doubled, then the total cost of the materials will be tripled.
what percentage (to the nearest 1%) of the sign is metal?
25%
33%
50%
67%
75%

the two may have that, even a breakdown is probably offered

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

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.
