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.

Find f(3).
f(x) = x2 + 5x - 9
A) 7
B) 10
C) 9
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.
Given f (x)= 5 (2 - x), what is the value of f(-6)
Answer:
f(-6)=40
Step-by-step explanation:
f(x)=5(2-x)
f(x)=10-5x
f(-6)=10-5*(-6)
f(-6)=10+30
f(-6)=40

Victoria and her friends are going to the skateboard shop to pickup some equipment. They buy two new skateboards for $87.98 each, 3 pairs of kneepads for $14.57 each, and 4 helmets for $21.24 each. What is their total cost? (hint: don't forget the $) * 50 points
Answer:
$304.63
Step-by-step explanation:
From the information provided, the total cost can be calculated by multiplying the price of each item for the amount purchased and adding up the results:
Total cost=($87.98*2)+($14.57*3)+($21.24*4)
Total cost=$175.96+$43.71+$84.96
Total cost= $304.63
According to this, the answer is that their total cost is $304.63.
can someone help me to solve 3/4÷1/2=
Answer:
3/4 ÷ 1/2 is one and one half or 3/2
Answer:
1.5 or 1 1/2
Step-by-step explanation:
3/4 divided by 1/2 is simply a reverse order of multiplication.
As you see if you swap the 1 and 2 in one half you get 2 over 1.
This changes the division sign to a multiplication sign.
Thus then you can multiply 3/4 by 2 to get 6/4.
6/4 then can be simplified as 1 and 1/2 or 1.5.
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.

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

Two years ago, Rita was three times older than Cheryl. In 3 years, Rita will be twice older than Cheryl. How old are the girls now?
Answer:
Cheryl's age = x = 7 years
Rita's age = y = 17 years
Step-by-step explanation:
Let
Cheryl's age = x
Rita's age = y
Two years ago, Rita was three times older than Cheryl
(y - 2) = 3(x - 2)
y - 2 = 3x - 6
y = 3x - 6 + 2
= 3x - 4
y = 3x - 4
In 3 years, Rita will be twice older than Cheryl
(y + 3) = 2(x + 3)
y + 3 = 2x + 6
y = 2x + 6 - 3
= 2x + 3
y = 2x + 3
Equate both equations
3x - 4 = 2x + 3
Collect like terms
3x - 2x = 3 + 4
x = 7 years
Substitute x = 7 into
y = 2x + 3
= 2(7) + 3
= 14 + 3
= 17
y = 17 years
Cheryl's age = x = 7 years
Rita's age = y = 17 years

Which statement describes the mapping? A. The mapping represents y as a function of x, because each y-value corresponds to exactly one x-value. B. The mapping does not represent y as a function of x, because two of the x-values correspond to the same y-value. C. The mapping represents y as a function of x, because each x-value corresponds to exactly one y-value. D. The mapping does not represent y as a function of x, because there are more x-values than different corresponding y-values.
Answer:
The answer is
C. The mapping represents y as a function of x, because each x-value corresponds to exactly one y-value.
Step-by-step explanation:
In mathematics, mapping is used synonymously to a function, and a function is basically a relation between two values or expressions say y and x
like the difference equation relating y and x.
In a function, for every value of x plugged into the function there is always a corresponding value of y.
Example.
Given the function
y=2x+5.
find the value of y when x=0
we are going to substitute x=0 and solve
y=2(0)+5
y=5
so for x=0 y=5
