Answer:

Option B

Step-by-step explanation:

The absolute value of a number is how far a number is from zero. We can use ' | | ' to represent the absolute volume of a number.  The distance, or absolute value, of -8 is 8.

We can represent this by writing:

|-8| = 8

Option B should be the correct answer.

Answer:

B

Step-by-step explanation:

The absolute value of a number means the distance from 0.

For example, |-2| is 2 units from 0.

|-8| = 8

-8 is 8 units from 0.

Step-by-step explanation:

Answer:

1) The mean is actually 31

2) True, the mean would be about 35.

3) True, the mean would change because more medals were added for the USA.

4) True, the mean would be effected because two is added. It results in a increase

All the statements given for the data are true.

True. The mean is calculated by adding up the total number of medals earned from 1972 to 2000 (including 1972 and 2000) and then dividing by the total number of years, which is 29. If the data for 1980 is removed, the total number of medals earned and the number of years both decrease by 1, so the mean remains the same.

False. The mean is calculated by adding up the total number of medals earned from 1972 to 2000 and then dividing by the total number of years, which is 29. Removing the data for 1980 would decrease the total number of years to 28, so the mean would increase if the total number of medals earned remains the same.

Not enough information. The number of silver medals earned in 2004 is not given, so it is impossible to determine if earning more than 31 silver medals would increase the mean.

True. The mean is calculated by adding up the total number of medals earned from 1972 to 2000 and then dividing by the total number of years, which is 29. If the USA had earned 2 more medals in 1988, the total number of medals earned would increase by 2, which would increase the mean.

Answer:

192 hours per day / 8 hours per person per day = 24 people

Step-by-step explanation:

Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:

720 person-days x 8 hours = 5,760 hours

To complete the project in 30 days, the total number of hours needed per day is:

5,760 hours / 30 days = 192 hours per day

Assign the numbers to the number line in the following order:

2.15=2.15

220%=2.2

9/4=2.25

*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:

2.15, 2.2, 2.25

Answer:

Step-by-step explanation:

To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.

Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.

The sum of the parts in the ratio is 8x + 5x + 2x = 15x.

We know that the total number of fruits is 120. Therefore, we can set up the following equation:

15x = 120

To solve for x, we divide both sides of the equation by 15:

x = 120 / 15

x = 8

Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:

Number of bananas = 2x = 2 * 8 = 16

So, there are 16 bananas in total.

We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

The decibel level of the sound of a monster truck is

Further explanation:

Decibel is defined as a unit which is used to measure the relative loudness or intensity of the sound.

In the question it is given that the intensity of the sound of a monster truck is watts per square inch.

The formula which is used to calculate the decibel level of a sound is as follows:

Here, represents the intensity of the sound of a monster truck and represents the threshold intensity of hearing at .

The value of the threshold intensity of hearing at is watts per square meter.

This implies that the valiue of is watts per square meter.

The intensity of the sound of a monster is given in unit of per square inch.

The relation between per square inch and per square meter is as follows:

So, the intensity of a monster truck is converted into per square meter as follows:

This implies that the value of is watts per square meter.

Now, substitute the value of and in the equation .

The approximated value of the above equation is as follows:

From the above calculation it is concluded that the decibel level of the sound of a monster truck is .

Step-by-step explanation:

Solution:

Given,

weight of Randy = 50 pounds

weight of his father = 160 pounds

difference in their weights = ?

Now,

difference in their weights =

weight of his father - weight of Randy

= 160 - 50

= 110 pounds

Therefore, the difference in their weights is 110 pounds.

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:
