Bess [88]

Answer: George receive 44 % of his full dose .

Step-by-step explanation:

Given : The amount for full dose : 25 grams

The amount received by George = 11 grams

Now, the percent of his full dose received by George :-

Can someone explain this

dolphi86 [110]

<h3>Answer: 28</h3>

=========================================================

Explanation:

Let x be the unknown angle we want to find. This angle is in degrees.

The diagram shows 19 is the opposite of this angle, and the side 35 is adjacent to the angle.

We use the tangent ratio to tie the two sides together

$\tan(\text{angle}) = \frac{\text{opposite}}{\text{adjacent}}\\\\\tan(x) = \frac{19}{35}\\\\x = \tan^{-1}\left(\frac{19}{35}\right)\\\\x \approx 28.4956386\\\\x \approx 28\\\\$

Note: The notation $\tan^{-1}$ refers to the inverse tangent, or arctangent.

Radium-226 is a metal with a half-life of 1600 years. If you start with 1 kilogram of radium-226, how much will remain after 20,

erica [24]

Ending Amount = Beginning Amount / 2^n
where 'n' = # of half lives
n = 20,000 / 1,600 = 12.5 half-lives

Ending Amount = 1 kg / 2^12.5
Ending Amount = 1 kg / 5,792.6
Ending Amount = 0.00017263 kilograms = 0.17263 grams
