Creeper, oh man

So we back in the mine, got our pick axe swinging from side to side,

Side, side to side

This task a grueling one,

Hope to find some diamonds tonight, night, night

Diamonds tonight

Heads up, you hear a sound,

Turn around and look up, total shock fills your body,

Oh no it's you again,

I could never forget those eyes, eyes, eyes,

Eyes, eyes, eyes

'Cause baby tonight,

The creeper's trying to steal all our stuff again,

'Cause baby tonight, you grab your pick, shovel and bolt again,

And run, run until it's done, done,

Until the sun comes up in the morn'

'Cause baby tonight, the creeper's trying to steal all our stuff again

Just when you think you're safe,

Overhear some hissing from right behind,

Right, right behind

That's a nice life you have,

Shame…

Explanation:

9.9 years

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
