The ratio of the weight of an iron plate to that of a copper plate is 15:8. If the iron plate weights 42kg more than the copper plate, find their respective weights.​

Hahaha that's to hard I don't know

it is so easy

the answer of this question is 22.4kg

answer: there are 453.592 grams in a pound.

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
