If you have 1 /18 profit out of 75 boxes how many more to make 180 dollars
krek1111 [17]
Assuming that means you make $0.06 per box (1/18 dollars per box) then you've made $4.17 off of the 75 boxes. 180-4.17 = 175.83 / .06 = 3165 more boxes.

You'd need to sell 3,165 more boxes.

Martin bought a new carpet to cover a room. The carpet is in the shape of a square and it covers an area of 200 ft2. How long is
svlad2 [7]

Answer:

14.14 ft long

Step-by-step explanation:

Martin bought a new carpet to cover a room. The carpet is in the shape of a square and it covers an area of 200 ft². How long is the side length of the carpet?

The Area the carpet covers is a square.

Hence, the Area of a square = (Side length)²

From the question, we are given the Area of the square = 200 ft²

Hence:

200 ft² = (Side length)²

We square root both sides.

√200 ft² = √(Side length)²

Side length = 14.142135624 ft

Approximately = 14.14 ft

The side length of the carpet is 14.14 ft long
