5/6 because it is the largest fraction
Answer:
Step-by-step explanation:
C = πd. An equivalent formula is C = 2πr.
Solving the first equation for π, we get π = C/d. Solving the second equation for r, we get π = C / (2r)
If an event has a probability P of happening, then there is a probability of (1-P) of the event not happening.
In this case the probability of the event is p=20/69.
Then, the probability of the event not happening is:

Answer: the probability of the event not happening is 49/69.
Answer: 900 inch
There is 3 ribbon in this question, Red ribbon(R), green ribbon(G) and purple ribbon(P). The relation would be
1. R= 9 inch
2. R= 1/10 G
3. P= 10 G
If you insert equation 1 into 2 then you will get:
9inch= 1/10G
G= 90 inch
After that insert the new equation into equation 3:
P= 10x 90 inch
P= 900inch
Answer:
48 cm
Step-by-step explanation:
The perimeter of the figure is the sum of the lengths of its sides.
Find the length of the unknown side
Let the unknown length be x cm.
Notice that the sum of the lengths of the unknown side and the side measuring 5 cm I equal to the length of the side measuring 9 cm.
x +5= 9
<em>Subtracting 5 from both sides:</em>
x= 9 -5
x= 4
Add up the lengths of all of the sides to find the perimeter. I will add the lengths starting from the side measuring x cm (or 4 cm), and sum them up in a clockwise manner. This ensures that none of the sides are overlooked.
Perimeter of the figure
= 4 +15 +9 +7 +5 +8
= 48 cm
