Answer:
H. 1/9.
Step-by-step explanation:
The area of a circle is calculated by solving for π.
The smallest circle has an area of π = π * 1 = π.
The middle ring will then have an area of π - π = π * 4 - π = 4π - π = 3π.
The largest ring will then have an area of π - π = 9π - 4π = 5π.
5π + 3π + π = 9π
So, the probability of hitting the innermost circle will be π / 9π = 1 / 9.
Your answer is H. 1/9.
Hope this helps!
Answer:
7
Step-by-step explanation:
There will be a maximum number of Mondays that can occur in 45 consecutive days when we start with a Monday as the first day.
Now, multiples of 7 are 7, 14, 21, 28, 35, 42, 49, ......
So, if today is Monday, the after 7 days there will be a Monday, after 14 days there will be a Monday and in this way, the 43nd day there will be a Monday.
Therefore, there will be Mondays with in 45 consecutive days. (Answer)
