A rectangular red sticker has a perimeter of 12 millimeters and an area of 8 square millimeters. What are the dimensions of the
bekas [8.4K]

Answer: 9" by 7"

Step-by-step explanation:

let the dimensions of the rectangle be x and y

equation 1:  xy=63

equation 2:  2(x+y)=32

first, rearrange the terms

(1′):  y=63/x

(2′):  y=16−x

(1′)-(2′):  0=63/x−16+x

multiply the equation by  x

0=x2−16x+63

0=(x−9)(x−7)

so x = 7 or x = 9

from this, y = 9 when x = 7 and y = 7 when x = 9

so, the dimension of the rectangle is 9″ by 7″

Sophia manages a landfill. She decides to measure the rate at which trash increases in volume to fill the landfill as the number
goblinko [34]

Answer:

\frac{m^3}{h}, \frac{cm^3}{h},  \frac{km^3}{h}

Step-by-step explanation:

If you look at the objects thrown as garbage, it's a two- or three-dimensional item that takes up space and also has mass and this is a solid waste.

And the landfill that dumps such garbage is also three-dimensional.

Hence, the volume module, if the object inside is a solid, either would be

m^3,cm^4,Km^3

As household numbers rise, landfill space increases.

So,

household\ number = Proportionality\times  landfill\ space

If H represents the number of household keeps,  then it will be a sufficient unit for the purpose of Sophia that is

\frac{m^3}{h}, \frac{cm^3}{h},  \frac{km^3}{h}
