<u>Answer
</u>
Option A) 17cm
<u>Explanation
</u>
Polygon R and polygon S are similar. This means the polygon R and S have equal number of sides.
Step 1 : Find the number of sides of polygon S
The perimeter of polygon S is 64 cm. If one side of polygon S is 8 cm
Therefore, Number of sides of polygon S = 64/8 = 8 sides
and number of sides of polygon R = 8 side
Step 2 : Find the number of sides of polygon R
The perimeter of polygon R is 136 cm,
Number of sides of polygon R = 136/8 = 17 cm
Therefore side length of polygon R = 17 cm
Answer:
do 1000 divide 10 and the ans will be 100

Answer:
C
Step-by-step explanation:
This problem is analogous to the extraction of 6 elements from a total of 10 elements. It's the same if they are marbles, chips, or in this case, people, as here we don't care about the order of the selection as we only are drawing a sample.
Thus, the problem implies solving the amount of possible combinations of 10 people if we take by 6. There is a formula for this and is:
10 C 6 = 10!(6!4!)
If we operate, knowing that for any number x, x!=x*(x-1)*(x-2)*...*1
10 C 6 = 10!(6!4!) = 10*9*8*7*6*...*1 / [(6*5*...*1) * (4*3*2*1)]
10 C 6 = 10*9*8*7*6! / [(6*5*...*1) * (4*3*2*1)]
We have a 6! multiplying and another dividing, so they get eliminated, and as 4*2=8 and 9=3*3
10 C 6 = 10*9*8*7*/ [(4*3*2*1)] = 10*3*3*8*7*/ [(8*3*1)]
We can eliminate the 8s and one of the 3s on the numerator with the one on the denominator:
10 C 6 = 10*3*7*/1 = 210/1= 210
So, option C
35% of 60 is 21. Hope this helped!
