Answer: The area of the Polygon D is 36 times larger than the area of the Polygon C.
Step-by-step explanation:
<h3>
The complete exercise is: "Polygon D is a scaled copy of Polygon C using a scale factor of 6. How many times larger is the area of Polygon D than the area Polygon C"?</h3>
In order to solve this problem it is important to analize the information provided in the exercise.
You know that the Polygon D was obtained by multiplying the lengths of the Polygon C by the scale factor of 6.
Then, you can identify that the Length scale factor used is:

Now you have to find the Area scale factor.
Knowing that the Length scale factos is 6, you can say that the Area scale factor is:

Finally, evaluating, you get that this is:

Therefore, knowing the Area scale factor, you can determine that the area of the Polygon D is 36 times larger than the area of the Polygon C.
Answer:
4250 children
Step-by-step explanation:
72-38=34 degrees
34 degrees therefore is 578 people
so, 1 degree is 17 people
There is 360 degrees in a circle so we must subtract the degrees of the men and female segments in order to know how many degrees children takes up:
360-72-38=250
250x17=4250 children
Answer:
B
Step-by-step explanation:
Using the student id given above, a = 19 and b = 7
Average speed for the first 54 km = 48+a km/h
Plug a = 19
Average speed for the first 54 km = 48+19 = 67 km/h
Average speed for remaining 86 km = 43-b km/h where b = 7
Average speed = 36 km/h
Average speed of entire journey = total distance / total time taken

Time taken to cover 54 km =
hr
Time take to cover 86 km =
hr
Total time taken = 3.2 hours.
Total distance = 86+54= 140 km
Average speed of the entire trip =
= 43.75 km/ h
It would be the fourth choice, 3y.
Remember, to get the product of two numbers, you must multiply them together.
Difference=subtraction
Sum=addition
Quotient=division
