The mass of 4m³ of silver is 41960kg. The density of gold is 19300kg/m³.
Calculate the difference in mass between 5m³ of silver and 5m³ of gold.

Material A has a density of 4.5g/cm³.
Material B has a density of 14g/cm³.
5kg of Material A and 200g of Material B form Material C.
Work out the density of Material C.

A solid sphere has a diameter of 12cm.
The sphere is made from glass.
The density of the glass is 3.02g/cm
Find the mass of the glass sphere.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

i don't know

step-by-step explanation:

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1
