Which of the following are required to find density using the density formula? Check all that apply.A.
Width of the substance
B.
Mass of the substance
C.
Amount of water in the substance
D.
Volume of the substance
Answers
(B) Mass of substance and (D) Volume of substance are required to find the density.
Final answer:
To find density using the density formula, the required elements are the mass and volume of the substance. Width or the amount of water in the substance is not needed.
Explanation:
The density of a substance can be found using the density formula, which is Density = Mass / Volume. To use this formula, you would need:
- Mass of the substance: This is the amount of matter in the substance and is typically measured in grams (g).
- Volume of the substance: This is the space that the substance occupies and is typically measured in cubic centimeters (cc or cm3).
The width of the substance or the amount of water in the substance are not required to find density using the density formula.

Answer:
The slopes of both lines are 2/3, and since they have different y-intercepts they are parallel.
Step-by-step explanation:
In order to find slope, you need to find the rise and run of the line, since slope is rise/run. Lets use the red line as an example: There are two points , (0,1) and (-2,-1) where there are solid points. Once you locate solid points, you can then count how many units up or down (rise) and how many left or right (run). If you do this on paper the lines should form a right triangle with the line as the hypotenus. Since we went up 2, right 3, the slope would be 2/3.

there are in one day. After that, it's a piece-o-cake.
1 day = 24 hours .
Now you can make a table:
1 day = 24 hours
2 days = 48 hours
3 days = 72 hours
4 days = 96 hours
5 days = 120 hours
6 days = 144 hours
7 days = 168 hours
8 days = 192 hours
9 days = 216 hours
10 days = 240 hours
8 days equal 192 hours (multiply 8 days by 24).
Or another way to think about it:
1 day 8 days
------------ = ----------
24 hours x hours
Cross multiplying,
x = 8*24
x = 192

What are linear equations?
Linear equations are equations that have constant average rates of change, slope or gradient
How to complete the remainder of the table for the given function rule?
From the question, the function rule is given as:
y = -2x +9
The table of values is given as:
x -4 -2 0 2 4
y 17
Next, we substitute the other values of x in the equation y = -2x +9
y = -2(-2) +9 = 13
y = -2(0) +9 = 9
y = -2(2) +9 = 5
y = -2(4) +9 = 1
So, the complete table of values is
-4 -2 0 2 4
y 17 13 9 5 1

The solution for the given expression will be 10√6.
In mathematics, an expression is a combination of numbers, variables, and mathematical operations such as addition, subtraction, multiplication, and division. It represents a mathematical computation or relationship.
An expression can consist of constants, variables, and operators. Constants are fixed numerical values, like 5 or 3.14. Variables, on the other hand, are symbols that represent unknown or changing values, such as x or y.
To solve this problem you use the property:
√ab = (√a)(√b)
The expression will be solved as below,
√600 = (√6)(√100) = √6(10) = 10√6
To know more about an expression follow

√ab = (√a)(√b)
Therefore:
√600 = (√6)(√100) = √6(10) = 10√6

Then
Age of Leah = x + 6
Age of John = 5 + (x + 6)
= x + 11
Total of their ages = 41
So
x + x + 6 + x + 11 = 41
3x + 17 = 41
3x = 41 - 17
3x = 24
x = 24/3
