Question

Some stalactites grow only 0.212 mm a year
How much would they grow in 10 years , 100years, 1000 years, 10 000 years


THANK YOUUUU SOOOOOOOO MUCHHH

Answer 1

this is very easy when you think about it...
if it grows .212 mm a year multiply that number by the number of years to find out how much it would grow

for example to find out how much it would grow it 10 years multiply .212 mm by 10 and you get 2.12mm

Answer 2

very simple
just times by 10, 100, 1000, and 10000

so for 10 years the answer is : 2.12 mm
for 100 years: 21.2mm
for 1000 years: ...


optional:
or you can change from mm to centimeters to meters if you want

i think this is right, superman doesnt like math that much

Answer 3

Add your zeros --for example 0.212 becomes 0.2120 for ten years --o.21200 for 100 years and so on.

Sorry my answer is totally wrong.
I am no good at math.
I do a lot of guessing and it drives my teachers crazy.

Answer 4

since you are dealing 10 years and adding 0's just move the decimal point the the right for each 0 .

10yrs= 2.12
100yrs=21.20
1000yrs=212.0
10000yrs=2120.0
