Answer 1

The length of the stalactite that grows for
`7.5*10^4` years is 375 inch.

Step-by-step explanation

Stalactites can grow at the rate of about 0.005 inch per year.

So, for finding the length that grows for
`7.5*10^4` years, we will just multiply the 'rate of growth' by the 'total time in years'.

Thus.....

`0.005(7.5*10^4)\\ \\ =0.005(7.5*10000)\\ \\ =0.005(75000)\\ \\ =375`

So, the length of the stalactite that grows for
`7.5*10^4` years is 375 inch.
