the diameter of earth is 7917.5 mi and the diameter of mercury is 3032 mi. how many times can mercury go inside earth. use 3.14

Law Incorporation [45]

Answer:

Mercury can enter 6.8 times inside the earth

Step-by-step explanation:

To solve this problem we have to calculate the volumes

First we calculate the radius

radius earth = 7917.5mi /2 = 3958.75mi

radius mercury = 3032mi / 2 = 1516mi

To calculate the volume of earth we have to use the following formula:

V = volume

r = radius = 3958.75mi

π = 3.14

V = ⁴⁄₃πr³

we replace with the known values

V = ⁴⁄₃ * 3.14 * (3958.75mi)³

V = 4.187 * 15671701.56 mi³

V = 65617414 mi³

The volume of earth is 65617414 mi³

To calculate the volume of mercury we have to use the following formula:

V = volume

r = radius = 1516mi

π = 3.14

V = ⁴⁄₃πr³

we replace with the known values

V = ⁴⁄₃ * 3.14 * ( 1516mi )³

V = 4.187 * 2298256 mi³

V = 9622797 mi³

The volume of mercury is 9622797 mi³

Now we divide the earth volume by the mercury volume

65617414 mi³ / 9622797 mi³ = 6.819

round to the nearest tenth

6.819 = 6.8

Mercury can enter 6.8 times inside the earth

6. If element Q has 11 protons, its atomic<br> is 11.

Vladimir79 [104]

Answer: If element Q has 11 protons, its atomic <u>number</u> is 11.

Step-by-step explanation:

The atomic number of a chemical element is the total number of protons that each atom of that element has.

In other words: it indicates the amount of protons that is present in the nucleus of an atom.

In this sense, the periodic table of the elements arranges the chemical elements in the form of a table, ordered by their atomic number (number of protons), by their configuration of electrons and their chemical properties.

the ratio of number of girls and boys in a class of 30 students is 7:8. if 5 new boys students admit in the class. what will be

Stells [14]

<h3>Given:</h3>

The ratio of number of girls and boys in a class of 30 students is 7:8

The ratio of number of girls and boys if 5 new boys admit in the class.

<h3>Assumption:</h3>

Let the number of students be x.

<h3>Solution:</h3>

According to the question,

7x + 8x = 30

or, 15x = 30

or, x = $\large {\tt {\frac{30}{15}}}$

or, x = 2

7x = 7(2) = 14

8x = 8(2) = 16

There were 14 boys and 16 girls in the school.

After admitting 5 new boys, we get

14 + 5 = <u>19</u>

The ratio of number of girls and boys now is 16:19.
