I need help PLEASE!! There are 9 grams of Strontium-90. Strontium-90 has a half-life of 28.8 years.

Use the formula A=P(12)th to calculate the time it would take for the given mass to degrade down to 0.41 grams. Calculate the solution for t to the nearest tenth using logarithms.

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

step-by-step explanation:

120 seems like the most sensible answer.

step-by-step explanation:

if there is only one topping on all caramel apples and there's 120 of them. then all apples should/will be covered in sprinkles. make sense?

47 - 90 = 43

43 - 180 = x

x = 137
