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.

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.

Known Variable

(0.125%) of her new net worth (8.12 * 10 ^ 10 to charity.

Variables that are asked

dollars are given to charity?

The answer

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

a mercury barometer is a device that uses the physical properties of mercury in a tube to measure barometric pressure. mercury barometers are used for : -

1. measurement of atmospheric pressure

2. determining the altitude of a place

3. weather forecasting

4. calibration and checking of aneroid barometers

5. application in fluid mechanics

6. measurement of pressure in aircrafts

7. surface weather analysis

8. preparation of barographs

9. usage in physical sciences like physics, astronomy & chemistry

10. preparation of aircraft altimeters

characteristics of mercury barometer : -

1.used to define and measure atmospheric pressure.

2.on the average at sea level the column of mercury rises to a height of about 760 mm.

3.this quantity is equal to 1 atmosphere.

4.it is also known as standard atmospheric pressure.

5.a barometer in which the weight of a column of mercury in a glass tube with a sealed top is balanced against that of the atmosphere pressing on an exposed cistern of mercury at the base of the mercury column, the height of the column varying with atmospheric pressure.
