Aroom is a square with walls 40 ft long each. if they hang the lights around the perimeter of the ceiling and then from the opposite corners to opposite corners to create an x on the ceiling, how many feet of lights are needed? use special triangles to answer both in the exact feet and to the nearest foot. if lights come in 30 ft strands. how many strands are needed?

10 strands

Step-by-step explanation:

Perimeter of the room = 40 + 40 + 40 + 40 = 160 ft

Diagonal length of the room = √(40² + 40²) = 40√2 ft

Total length = 160 + 40√2 + 40√2 = 273.14 ft (Nearest hundredth)

Strands needed =  273.14  ÷ 30 =  10 (Next nearest whole number)

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.

step-by-step explanation:

pakistan's principal natural resources are arable land and water. about 25% of pakistan's agriculture accounts for about 21% [1] of gdp and employs about 43% of the labour force. in pakistan, the most agricultural province is punjab where wheat and cotton are the most grown.
