how many times larger is the mass of an average grain of rock song than the mass of an average grain of table salt
Answer:
40
Step-by-step explanation:
The sample answer for edmentum is: The first factor of the mass of an average grain of rock salt is 40 times the first factor of the mass of an average grain of table salt. So, the mass of an average grain of rock salt is 40 times greater than the mass of an average grain of table salt.
The mass of an average grain of rock sand is 43.4 times larger than the mass of an average grain of table salt
What is scale factor?Scale factor is used to compare the size of two objects. Mathematically, we can write -
{K} = S{O1}/S{O2}
13 mg
Given is to compare the mass of an average grain of rock sand than the mass of an average grain of table salt.
The mass of an average grain of rock sand is : 13 mg
The mass of an average grain of table salt is : 0.3 mg
So, we can write that -
{K} = M{rock sand}/M{table salt}
{K} = 13/0.3
{K} = 130/3
{K} = 43.4
So, it can be concluded that the mass of an average grain of rock sand is 43.4 times larger than the mass of an average grain of table salt.
Therefore, the mass of an average grain of rock sand is 43.4 times larger than the mass of an average grain of table salt.

Samantha has 4 1/2 gallons of lemonade for her daughter’s birthday party. Each gallon of lemonade contains 1.5 grams of fat. How many grams of fat are contained in all the lemonade Samantha has for the party?
Answer:
6.75 grams
Step-by-step explanation:
Total amount of lemonade with Samantha = 4 1/2 gallons
= (4*2 + 1)/2 gallons = 9/2 gallons = 4.5 gallons
Amount of fat in 1 gallon of lemonade = 1.5 grams
To find amount of fat in 4.5 gallons lemonade
we multiply both side of equation with 4.5
Amount of fat in 1*4.5 gallon of lemonade = 1.5*4.5 grams = 6.75 grams
Thus,
there is 6.75 grams of fat in all the lemonade Samantha has for the party

In general, % of the values in a data set lie at or below the 16th percentile. % of the values in a data set lie at or above the 24th percentile.. If a sample consists of 800 test scores, of them would be at or below the 86th percentile. If a sample consists of 800 test scores, of them would be at or above the 14th percentile.
Complete Question
In general,_______ % of the values in a data set lie at or below the 16th percentile.
_________ % of the values in a data set lie at or above the 24th percentile.
If a sample consists of 800 test scores, _______ of them would be at or below the 86th percentile. If a sample consists of 800 test scores,_______ of them would be at or above the 14th percentile.
Answer:
In general, 16 % of the values in a data set lie at or below the 16th percentile.
24 % of the values in a data set lie at or above the 24th percentile.
If a sample consists of 800 test scores, 688 of them would be at or below the 86th percentile. If a sample consists of 800 test scores, 688 of them would be at or above the 14th percentile.
Step-by-step explanation:
Generally percentile defines the percentage of a data set that is below or at a value that is being considered.
Hence the percentage of the values of a data set that lies below or at the 16th percentile is 16%
Also the values of a data set that lies below or at the 24th percentile is 24%
Given a sample of 800 test scores , the number number of test scores that will be at or below the 86th percentile is 86% of 800 which is mathematically represented as
[tex]k = \frac{86}{100} * 800[/tex]
[tex]k = 6 88[/tex] test scores
Given a sample of 800 test scores , the number number of test scores that will be above the 14th percentile is (100 - 14 = 86 )% of 800 which is mathematically represented as
[tex]a = \frac{86}{100} * 800[/tex]
[tex]a = 6 88[/tex] test scores
