Answer:
see the attached
Step-by-step explanation:
To fill in the data table, you need information about the layers of the Earth. That information is provided in the second attachment.
Among other things, it shows the density of the rock layers varies over a range of almost 6 to 1 from the top layer to the inner core. Your representative liquids vary in density over a range of about 1.8 to 1, so clearly cannot match the relative densities.
In the attached spreadsheet, we have used the average of the top and bottom density values for each layer to represent the density of the layer. Then we did a linear mapping so that the minimum density maps to lamp oil, and the maximum density maps to honey. (You get slightly different results if you use a different mapping strategy.)
For your convenience in stacking your "density cylinder", we have shown the relative thickness of each of the layers as a percentage of the overall radius of the Earth. That is, if your cylinder is 100 mL deep, for example, then the top layer will be 0.5 mL deep, the next layer 11.3 mL deep, and so on.
__
We have elected not to use alcohol for the top layer, because it is miscible with all of the liquids immediately below that in the table. That is, you could not maintain alcohol as a separate layer in your cylinder because it would dissolve into the layer below. It might take a little effort (or care) to keep the lamp oil separated from the vegetable oil, as we expect those might try to mix, as well.
If you compare the scaled density values with the values for the "representative" liquids we have chosen, you will see that some are closer than others. The idea is to try to get the best match, while also choosing liquids that don't mix well.
List all the factors of 33 from least to greatest. Enter your answer below,
using a comma to separate each factor.
Answer here
Answer:
1,3,11,33
Step-by-step explanation:
33 can be divided by itself, 11,3 and 1 without leaving a remainder.
The factors of 33 from least to greatest is 1, 3, 11, 33.
The factors of 33 are the numbers that, when multiplied by another number, result in 33.
The factors of 33 are:
33 = 1 x 33
33 = 3 x 11
So, the factors are:
1, 3, 11, 33
Now, the least factor is 1 and Greatest factor is 33.
Thus, the factors of 33 from least to greatest is 1, 3, 11, 33.

The median number of magazine appearances made by 7 models is 5. The range of number of magazine appearances by those models is 5. Determine if the following statement is true, is false, or does not contain enough information. If the fewest magazine appearances is 3, then the greatest number of appearances is 9.
Answer:not enough information
Step-by-step explanation:
Using definition of range = greatest - lowest , we found that given statement is false.
What is range of a given data?Range of a data is the difference between the highest and lowest quantity in the given data.
For example : Given data is 2,5,9,5,1
Range of this data = Highest - Lowest = 9-1 =8
Given the data of the number of appearances made by 7models
Median = 5
Range = 5
If the fewest magazine appearances is 3
We know that Range = Greatest number of appearances - fewest appearances
⇒ 5 = Greatest number of appearances - 3
⇒ 5 +3 = Greatest number of appearances
∴Greatest number of appearances = 5+3 = 8
But given is that the Greatest number of appearances will be 9 in the given statement.
∴ The given statement is false.

Find the measure of each angle.
(3x + 5)^(10x-7)
The measure of angle TQR is 47 degrees and the measure of angle TRS is 133 degrees
In order to determine the measure of each angle, the value of x has to be determined first
The sum of angles on a straight line is 180 degrees
Thus : (3x + 5)° + (10x - 7)° = 180°
3x + 5 + 10x - 7 = 180
combine similar terms
3x + 10x = 180 - 5 + 7
add similar terms
13x = 182
divide both sides of the equation by 13
x = 14°
Substitute for x in (3x + 5)° and (10x - 7)°
(3x + 5)° = 3(14) + 5 = 47°
(10x - 7)° = 10(14) - 7 = 133°

A symphony orchestra is arranged in a semicircle around the conductor. The rows are about 3 feet apart, with the first row about 6 feet from the conductor. A mid-sized orchestra has about 6 rows of chairs. What is the approximate delay between the instant when a play at the 6th row start a note and when the conductor hears the note?
Answer:
19 ms
Step-by-step explanation:
We need to find the time it takes for the sound from the 6th row gets to the conductor.
Since there are 6 rows and each row is 3 feet apart, since the orchestra is arranged in a semi-circular manner around the conductor, the distance from the 6 th row to the 1st row is (6 - 1) × 3 = 5 × 3 = 15 feet.
Now, since the conductor is 6 feet from the first row, his distance from the 6th row is 15 feet + 6 feet = 21 feet.
So, time approximate delay between the instant when a play at the 6th row start a note and when the conductor hears the note, t = distance between 6th row and conductor/speed of sound.
Speed of sound = 343 m/s
distance between 6th row and conductor = 21 feet. In meters, it is 21 × 0.3048 m = 6.4008 m
t = 6.4008 m ÷ 343 m/s
= 0.019 s
= 19 ms

D) 15
Answer:
f(3) = 15. Correct: D)
Explanation:
Numeric Value of a Function
The value of a function f(x) when x = a is calculated by replacing the x for a. We have the function:
[tex]f(x)=x^2+5x-9[/tex]
It is required to find f(3), or the numeric value of f when x=3. Replace x for 3
[tex]f(3)=3^2+5(3)-9[/tex]
[tex]f(3)=9+15-9[/tex]
[tex]f(3)=15[/tex]
A) Incorrect. f(3) is not 7
B) Incorrect. f(3) is not 10
C) Incorrect. f(3) is not 9
D) Correct. f(3) =15 as found above.

Michelle invests $15,000 in a partnership that has four other partners.The total investment of all partners is $ 240,000. What percent of the business does Michelle own?
Michelle owns about 6.25% of the total investment.
What is the percentage?The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that Michelle invests $15,000 in a partnership that has four other partners. The total investment of all partners is $240,000.
The percentage of investment will be calculated as below:-
Percentage = ( 15000 / 240000 ) x 100 %
Percentage = 00625 x 100%
Percentage = 6.25%
Therefore, Michelle owns about 6.25% of the total investment.
