Can you ? i'll give out brainliest.

a crane has a cable with a breaking strain of 6400kg measured to 2 significant figures.

it is used to lift crates which weigh 90kg measured to the nearest 10kg.

what is the greatest number of crates that can safely be lifted at one time without breaking the cable?

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
