<em> The amount to donate is 1,015.10⁸  </em>

\boxed{\boxed{\bold{Further~explanation}}}  

In mathematical calculations, the symbol of percent is used  

The percent is a number that shows a comparison of the number 100 or can be called per hundred (symbol%)  

Formula used:  

\large{\boxed{\bold{Percentage\:=\:\frac{Total\:Section}{Total\:Amount}\:\times\:100\percent}}}

Fractions either ordinary or mixed (consisting of numerators and denominators) or decimal forms can we change to a percentage  

The percentage can be expressed as a decimal by moving the decimal point two places to the left

One way to convert ordinary fractions to percent forms (The easiest way) is to multiply the fraction by 100% or By changing the denominator to 100 because percent is the percent. Multiply the numerator and denominator with the same number.

<em>Known Variable  </em>

<em>Variables that are asked  </em>

dollars are given to charity?  

<em>The answer  </em>

The desired percentage to donate from the number 8,12 .10¹⁰ is 0.125% so the amount is:  

0.125% x 8,12 10¹⁰ = 101500000 = 1,015.10⁸

ANSWER: $101,500,000

EXPLANATION: The individual's net worth is 8.12 X 10^{10} .

To find the dollars donated to charity from the individual's net worth which will be one eight percent;

We can use the following method;

By simply multiplying the one eighth (0.125) percent with the new net worth we can get the answer.

0.125 X 8.12 X 10^{10} = $101,500,000

Therefore, the amount donated by the individual in dollars was $101,500,000.

Identify the combustion reaction. c4h12 + 7o2 ⟶ 6h2o + 4co2 2h2 + o2 ⟶ 2h2o al2s3 ⟶ 2al + 3s cl2 + 2kbr ⟶ 2kcl + br2
Levart [38]
From the given equations, the combustion reaction is;
C₄H₁₂ + 7O₂ --> 4CO₂ + 6H₂O
Combustion reactions are when organic compounds react with O₂ to produce water and CO₂. From the given reactions, C₄H₁₂ is an organic compound that reacts with O₂ to produce water and CO₂.
Therefore this is the only reaction that follows the general equation for combustion.

An unknown radioactive substance has a half-life of 3.20hours . If 46.2g of the substance is currently present, what mass A0 was
iogann1982 [59]

Answer:

a) a0 was 46.2 grams

b) It will take 259 years

c) The fossil is 1845 years old

Explanation:

<em>An unknown radioactive substance has a half-life of 3.20hours . If 46.2g of the substance is currently present, what mass A0 was present 8.00 hours ago?</em>

A = A0 * (1/2)^(t/h)

⇒ with A = the final amount = 46.2 grams

⇒ A0 = the original amount

⇒ t = time = 8 hours

⇒ h = half-life time = 3.2 hours

46.2 = Ao*(1/2)^(8/3.2)

Ao = 261.35 grams

<em>Americium-241 is used in some smoke detectors. It is an alpha emitter with a half-life of 432 years. How long will it take in years for 34.0% of an Am-241 sample to decay?</em>  

t = (ln(0.66))-0.693) * 432 = 259 years

It will take 259 years

<em>A fossil was analyzed and determined to have a carbon-14 level that is 80% that of living organisms. The half-life of C-14 is 5730 years. How old is the fossil?</em>

<em />

t = (ln(0.80))-0.693) * 5730 = 1845

The fossil is 1845 years old
