an element with a mass of 540 grams decays by 17.9% per minute to the nearest tenth of a minute how long will it be until there
STatiana [176]

Answer:

It'll take approximately 9.1 minutes

Step-by-step explanation:

The decay of this element can be modeled by the following expression:

m(t) = 540*(1 - 0.179)^t

Where m is the mass of the element in a given minute t. This expression comes from a compounded interest formula, with negative rate, since they will work in the same manner. Therefore to find how long until it reaches 90 g, we need to make m = 90 and solve for t.

90 = 540*(0.821)^t

(0.821)^t = 90 / 540

(0.821)^t = 1/6

ln(0.821^t) = ln(1/6)

t*ln(0.821) = ln(1) - ln(6)

t*ln(0.821) = - ln(6)

t = -ln(6)/ln(0.821) = 9.08452

It'll take approximately 9.1 minutes

AlexFokin [52]
<em>Hello there, and thank you for asking your question here on brainly.

<u>Short answer: 3
</u>
Why?

You can find this out by dividing 48 and 16. The number you get from it is how much 16s are in 48, which is the answer to our question. (48 / 16 ==> 3) Check: 16 * 3 = 48. This is correct.

Hope this helped you! ♥</em>
