Answer:
The scale factor from Figure A to Figure B is 1/2
Step-by-step explanation:
<u><em>The correct question is</em></u>
Figure B is a scaled copy of Figure A.
What is the scale factor from Figure A to Figure B?
The picture in the attached figure
we know that
A dilation is a non rigid transformation that produce similar figures
If two figures are similar, then the ratio of its corresponding sides is proportional
In this problem Figure A and Figure B are similar
so
To find out the scale factor, determine the ratio of its vertical corresponding sides
The vertical side of figure A is 4 units
The corresponding side in figure B is 2 units
The scale factor is less than 1
so
The dilation is a reduction
therefore
The scale factor from Figure A to Figure B is 1/2
Answer: THE GRAPH IS ATTACHED.
Step-by-step explanation:
The Slope-Intercept form of the equation of a line is:
Where "m" is the slope of the line and "b" is the y-intercept.
In this case, you have the first equation:
You can identify that:
If you convert the Mixed number to a Decimal number, you get:
Then, knowing the slope and the y-intercept, you can graph the line.
The second equation is:
Solve for "y":
Knowing that:
You can graph the line.
The point of intersection between both lines, is the solution of the system. This is:
Observe the graph attached.
Answer:
The correct answer is 0.0667 centimeters.
Step-by-step explanation:
Diameter of earth is 12700 kilometers.
Width of the solidified ocean crust is 35 kilometers.
Ratio between the diameter of the earth and the solidified crust is .
Now the earth is shrunken to a size of a basketball with the diameter as 24.2 centimeters. Let the thickness of the Earth's crust in this model be x centimeters.
Ratio between the diameter of the model earth and the solidified crust is .
But this ratio of the real Earth and its model must be equal.
∴ =
⇒ x = 0.0667 centimeters.
