1. A sphere has a diameter of 12
centimeters. What is the volume of the
sphere?
A 72 cm
C 200 cm
B 144 cm
D 288,7 cm

Answers

Answer 1

Answer:

Volume of the sphere = 902 cm³ (Approx.)

Step-by-step explanation:

Given:

Diameter of circle = 12 centimeter

Find:

Volume of the sphere

Computation:

Radius of circle = Diameter of circle / 2

Radius of circle = 12 / 2

Radius of circle = 6 centimeter

Volume of the sphere = [4/3]πr³

Volume of the sphere = [4/3][22/7][6]³

Volume of the sphere = [4/3][22/7][216]

Volume of the sphere = [1.33][3.14][216]

Volume of the sphere = [216][4.1762]

Volume of the sphere = 902.05

Volume of the sphere = 902 cm³ (Approx.)

Answer:

5.6

........................................................................

Answer:

x = 5.6

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2+b^2 = c^2

4.8 ^2  + x^2 = 7.4^2

23.04 +x^2 =54.76

Subtract 23.04 from each side

x^2 = 54.76 - 23.04

x^2 =31.72

Take the square root of each side

x =5.632051136

Rounding to the nearest tenth

x = 5.6

Step-by-step explanation:

We have to find: Angle A, also called "x

We are given: Side opposite to x and the hypotenuse of the triangle.

Trigonometric Ratio that would be used: Sin

=> Sin(x) = Opposite/Hypotenuse

=> Sin(x) = 10/17

Una mamá tiene el cuádruplo de la edad de su hijo, y dentro de 5 años, tendrá el triple de años que el. Indica que edad tienen ambos.

Answers

Answer:

The son age is 10 years

And, his mother age be 40 years

Step-by-step explanation:

Given that

The mother is four times the age of her son

And,  in 5 years, she will be three times as old as him

We need to find out the ages of both

Here we assume that the age of her son be x

So the mother age be 4x

Now in 5 years, her mother would be 3 times as old as his son

So,

4x + 5 = 3(x + 5)

4x + 5 = 3x + 15

x = 10

The son age is 10 years

And, his mother age be 40 years

*40 people responded that they use mouthwash.

*Of the people who use mouthwash, 30 people use floss.

*55 people responded that they do not floss.

*45 people responded that they don't floss and don't use mouthwash

Answers

Answer:  The image of the completed table is shown below

In the completed table, we have the following values (left to right)

Row One: 30, 10, 40Row Two: 15, 45, 60Row Three: 45, 55, 100

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

Explanation:

We're told that "40 people responded that they use mouthwash". That means we'll write "40" at the very end of the "use mouthwash" row. This represents the total number of people who use mouthwash, since we're underneath the "total" in that far right column.

Then we're further told that "Of the people who use mouthwash, 30 people use floss", so we'll write "30" in the first row, first column blank space. These are the people who both floss and use mouthwash. Because earlier we know 40 people use mouthwash overall, this leaves 40-30 = 10 people who use mouthwash, but they don't floss.

To summarize so far: In row 1, we have the following values from left to right: 30, 10, 40

The first two items of this row must add to the last item.

---------------------

Now onto row 2

Since 40 people use mouthwash, and 100 people were surveyed, this means that 100-40 = 60 people do not use mouthwash.  The value 60 goes at the very end of row 2. This represents another total.

Like earlier, the first two items must add to the last. So 40+60 = 100.

Now turn to the fact that "45 people responded that they don't floss and don't use mouthwash". This tells us that "45" will be in the "no mouthwash" row and "don't floss" column.

We have 60 people who don't use mouthwash, and 45 of those people also don't floss. Therefore, 60-45 = 15 people do floss but they don't use mouthwash. We'll write "15" in the second row, first column.

Along row 2, we have the following values: 15, 45, 60

----------------------

Row 3

For each column, add up the first two items to get the third one. This will lead to the totals along this bottom row.

Floss: 30+15 = 45Don't Floss: 10+45 = 55 .... note how this matches up with the third piece of information your teacher provided

The third column is already done, but again we can see that 40+60 = 100.

Furthermore, the first two items of the third row add to 45+55 = 100 which helps confirm our answers.

The full completed table is shown below.

------------------------

To summarize, we are effectively just sorting the values given to us to write them into the table. Then we use a bit of algebraic detective work to find out what values are missing so we fill out the completed table.

Miko and her parents rent boats for the afternoon. Her parents rent a canoe and Miko rents a kayak. • It costs $20.49 to rent a canoe plus an additional $7.49 for each hour. • It costs $17.99 to rent a kayak plus an additional $5.99 for each hour. Miko and her parents rent one canoe and one kayak for the same amount of time, and their total cost for the rentals is $78.92. Write and solve an equation to determine the amount of time, in hours, that they rented the kayak and canoe.

Answers

Answer:

Kayak and Canoe rented for 3 hours

Step-by-step explanation:

Let the time for which they rent canoe & kayak = x hours  

Total canoe cost = 20.49 + 7.49x , Total kayak cost = 17.99 + 5.99x  

Given] Total canoe & kayak cost = 78.92

So, (20.49 + 7.49x) + (17.99 + 5.99x) = 78.92

20.49 + 17.99 + 7.49x + 5.99x =  78.92 ; 38.48 + 13.48x = 78.92

13.48x = 78.92 - 38.48 ; 13.48x = 40.44

x = 40.44 / 13.48 ; x = 3

Water is drawn up into the atmosphere as it evaporates from the ground, rivers, lakes, oceans, flora. and fauna. This water collects in our atmosphere. Then, it gathers together in concentrations that form clouds. Eventually, the clouds become too dense with water. This causes precipitation to begin and fall back down through our atmosphere. It lands on the Earth's surface as rain or snow. This precipitation then travels through the ground, plants, rivers, lakes and oceans. From there, it evaporates back up into the air to begin the cycle again.Water is restorative in nature. A threat to the natural restorative nature of the water cycle is acid rain. Acid rain is caused by certain gas emissions in our atmosphere. Volcanoes release some of these gases naturally. However, the primary cause of these harmful emissions is human activity and industry. Large factories and gas-powered vehicles send harmful pollutants into the air. As these harmful gases are released into the atmosphere, they are caught in evaporated water molecules, causing acid clouds to form. The gases are also picked up by precipitation that falls from the clouds. The gases mix with the water molecules to form acids, which then fall from the sky as rain or snow. As air pollution continues, acid rain in the water cycle worsens.Acid rain can poison plants and be harmful to animals. It is so strong that it slowly breaks down buildings and stone. The acids break down building materials. They can also burn the leaves of plants. Acid rain can even change the chemical make up of soil, making it toxic to plant life. It can also lower the productivity of farms and crop yields. As rivers and lakes become more acidic, acid rain destroys fish and aquatic life. Ocean creatures with exoskeletons are at risk of acidic waters. The acid weakens and dissolves their exoskeleton. There are many harmful effects on the water cycle caused by acid rain.Which information in the article helps the reader understand the overall text structure? (2 points) aThe author explains how eroding buildings, trees, and other landscapes cause issues in the rain, making it acidic and explains how it affects the water cycle. bThe author explains how pollution contributes to the creation of acid rain and also explains how acid rain can negatively affect waterways, trees, and buildings. cThe author explains how pollution contributes to the creation of acid rain and then explains how this affects the research that scientists do on the environment. dThe author explains how the changing temperature affects precipitation in the water cycle and how this has a positive or negative affect on the farming industries.
