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.

The table shows how fast four students ran the 200-meter dash.
200-Meter Dash Results
Student Time (seconds)
Ben 40.53
Katie 34.02
Griffin 29.80
Kristin 44.56
How much faster did Griffin run the 200-meter dash than Ben? Enter your answer in the box.
Answer:
Griffin was 10.73 seconds faster than Ben
Step-by-step explanation:
Here, given the information in the question, we want to know how faster was Griffin than Ben in the race
Mathematically, that will be;
|29.80 - 40.53| = 10.73
This shows that Griffin was 10.73 seconds faster than Ben

Answer:
A & B
Step-by-step explanation:
See attachment for complete question
Given
[tex]y = \frac{1}{2}x[/tex]
Analyzing the given options
Option A:
[tex]6y = 3x[/tex]
Divide both sides by 6
[tex]\frac{6y}{6} = \frac{3x}{6}[/tex]
[tex]y = \frac{3x}{6}[/tex]
[tex]y = \frac{1}{2}x[/tex]
This is true for the given expression:
Option B:
From the graph:
x = 2, when y = 1
x = 4, when y = 2
Solving for the slope:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{2 -1}{4 - 2}[/tex]
[tex]m = \frac{1}{2}[/tex]
The equation is then calculated as:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - 1 = \frac{1}{2}(x - 2)[/tex]
[tex]y - 1 = \frac{1}{2}x - 1[/tex]
Add 1 to both sides
[tex]y - 1 +1 = \frac{1}{2}x - 1 + 1[/tex]
[tex]y = \frac{1}{2}x[/tex]
This is also true for the given expression.
Option C:
From the graph:
x = 2, when y = 4
x = 4, when y = 8
Solving for the slope:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{8 - 4}{4 - 2}[/tex]
[tex]m = \frac{4}{2}[/tex]
[tex]m =2[/tex]
The equation is then calculated as:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - 4 = 2(x - 2)[/tex]
[tex]y - 4 = 2x - 4[/tex]
Add 4 to both sides
[tex]y - 4 + 4= 2x - 4 + 4[/tex]
[tex]y = 2x[/tex]
This isn't true for the given expression.
Option (D):
From the table:
x = 2, when y = 1
x = 4 when y = 3
Solving for the slope:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{3 - 1}{4 - 2}[/tex]
[tex]m = \frac{2}{2}[/tex]
[tex]m = 1[/tex]
The equation is then calculated as:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - 1 = 1 * (x - 2)[/tex]
[tex]y - 1 = x - 2[/tex]
[tex]y = x - 2 +1[/tex]
[tex]y = x - 1[/tex]
This isn't true for the given expression.

How can I describe a ordered pair
Answer:
Ordered Pair An ordered pair is a composition of the x coordinate (abscissa) and the y coordinate (ordinate), having two values written in a fixed order within parentheses. It helps to locate a point on the Cartesian plane for better visual comprehension. The numeric values in an ordered pair can be integers or fractions.
Step-by-step explanation:
i hope this helped! :)
Answer:
An ordered pair contains the coordinates of one point in the coordinate system. A point is named by its ordered pair of the form of (x, y). The first number corresponds to the x-coordinate and the second to the y-coordinate. To graph a point, you draw a dot at the coordinates that corresponds to the ordered pair.

Bob needs his refrigerator fixed. The repairman will charge Bob a flat fee of $40 plus an additional $15 for each hour he needs to work on it. Write an equation to represent Bob's cost to repair his refrigerator. Use y for the total cost and x for hours.
Given:
Fixed fee = $40
Additional fee = $15 per hour
To find:
The equation to represent Bob's cost to repair his refrigerator.
Solution:
Let y be the total cost for x hours.
Additional fee for one hour = $15
Additional fee for x hour = $15x
Total cost = Fixed fee + Additional fee
[tex]y=40+15x[/tex]
Therefore, the required equation is [tex]y=40+15x[/tex].

Gabriela Mistral was a poet, diplomat, teacher and humanitarian. Each week she worked a certain amount of days as a poet diplomat teacher and humanitarian. This ratio was one day as a poet to one day as a diplomat to three days as a teacher to two days as a humanitarian how many days must she work as a humanitarian if she works 12 days as a teacher?
Answer:
Gabriela Mistral works as a humanitarian for [tex]8[/tex] days.
Step-by-step explanation:
Gabriela Mistral was a poet, diplomat, teacher and humanitarian such that each week she worked a certain amount of days as a poet diplomat teacher and humanitarian.
Ratio is [tex]1:1:3:2[/tex]
Let [tex]x[/tex] denotes total number of days Gabriela Mistral work.
As she works 12 days as a teacher,
[tex]\frac{3}{7}x=12\\ x=\frac{7}{3}(12)\\ x=28[/tex]
Total number of days [tex]=x=28[/tex]
So,
she works as a humanitarian for [tex]\frac{2}{7}x=\frac{2}{7}(28)=8[/tex] days.

Point P is on line segment OQ. Given OQ = 4x + 2, PQ = 4x – 10, and
OP = 3x – 3, determine the numerical length of OQ.
Answer:
22
Step-by-step explanation:
Since, Point P is on line segment OQ.
[tex]\therefore O - P - Q\\\\
\therefore OP + PQ = OQ\\\\
\therefore 3x - 3 + 4x - 10 = 4x + 2\\\\
\therefore 7x - 13 = 4x + 2\\\\
\therefore 7x - 4x = 2 + 13\\\\
\therefore 3x = 15\\\\
\therefore x = \frac{15}{3}\\\\
\huge \purple {\therefore x = 5} \\\\
OQ = 4x + 2 = 4\times 5 + 2 = 20 + 2\\\\
\huge \orange {\boxed {OQ = 22}} [/tex]
Answer:
OQ=5
Step-by-step explanation:
The formula:
OP+PQ=OQ
Fill in the values for each segment using the values given:
3x-3+4x-10=4x+2
OP^ PQ^ OQ^
Simplify by adding like terms:
3x-3+4x-10=4x+2
7x-3-10=4x+2
add 13 to the right to isolate the variable:
7x-13=4x+2
+13 +13
7x=4x+15
subtract 4x to the left to isolate the variable:
7x=4x+15
-4x -4x
3x=15
Divide both sides by 3 to get the variable by itself:
3x=15
3 3
x=5 so OQ=5
