cluponka [151]

Answer:

The number of detective widgets out of 22,000 widgets is 828 widgets

Step-by-step explanation:

Given as :

The total number of widgets = 850

The number of detective widgets out of 850 = 32

Or, Out of 22,000 widgets , the number of detective widgets = 828.23

Hence, The number of detective widgets out of 22,000 widgets is 828 widgets Answer

Crank

  Think about what a half-life means as a table.

years amount Left

20 1/2

40 1/4

60 1/8

80 1/16

Starting at t = 0, the amount left (or density) = (1/2)^(t/20)

For t =35, the decay factor = .297

Since you need to work backwards, divide by that factor.  6 / .297 = 20.18 mg per sq cm
