Answer 1

ratio and proportion 8.5 cm/52 grams= 10 cm/x grams cross multiply 8.5x=520 x= 61.18 grams hope this helps

Answer 2

we know that

a piece of cable
`8.5` cm long weighs
`52` grams

so

by proportion

`(52)/(8.5)(grams)/(cm)=(x)/(10)(grams)/(cm) \\ \\8.5*x=10*52\\ \\x=(10*52/)8.5\\ \\x=61.18\ grams`

therefore

the answer is

`61.18\ grams`
