The perimeter of a building is 900 feet. If the length of the building is 400 feet, find the width. How many lights will be need
Helen [10]

Answer:

The width of the building is 50 lamps and 60 lamps will be needed.

Step-by-step explanation:

The perimeter is computed by the sum of the sides of the building, since the length and width are equal on the oposite sides of the building, the perimeter is given by:

perimeter = 2*length + 2*width

900 = 2*(400) + 2*width

2*width + 800 = 900

2*width = 900 - 800

2*width = 100

width = 100/2 = 50 feets

To know how many lights bulbs will be needed we need to take the perimeter of the building and divide it by the space between the lamps. We have:

number o lamps = 900/15 = 60 lamps

12³.2².4⁴ / 4³.2.12²
Nuetrik [128]
Remember
\frac{xyz}{abc}=( \frac{x}{a} )( \frac{y}{b} )( \frac{z}{c} )
and
\frac{x^m}{x^n}=x^{m-n}

split them to have same bases
\frac{12^32^24^4}{4^32^112^2}=
( \frac{12^3}{12^2} )( \frac{4^4}{4^3} )( \frac{2^2}{2^1} )=
(12^1)(4^1)(2^1)=
