Answer 1

t= 41.2 minutes

Explanation:

`16=290(0.5)^{(t)/(10) }`

Divide by 290 to get the exponential expression alone

`(16)/(290) \\(8)/(145)=(.0.5)^(t/10)`

Use Logs to solve

`x=a^(y)` is equal to
`y=log_(a) x`

`(t)/(10) =log_(0.5) (8)/(145)` (put in calculator)

`(t)/(10) = 4.18`

t= 41.2 minutes
