It costs a family $216 to refinish a wood floor. they want to refinish floor in a larger room. the ratio of lengths of corresponding sides 3/4. how much would it cost to refinish wood floor in a larger room?

Option C. $384

Step-by-step explanation:

Cost to refinish a wood floor is given as $216

Family has to refinish floor of a larger room and ratio of the corresponding sides of the rooms is .

Since sides are in the ratio of so area will be in the ratio of

Now ratio of the cost to refinish the rooms will be same as the ratio in their areas.

Let $x be the cost to refinish the larger room.

By cross multiplication

9x = (16)(216)

9x = 3456

x =

x = $384

Therefore Option C is the answer.

a negative exponent is translated as follows:

so, we have

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
