Answer:
The correct answer is last option 78.5%
Step-by-step explanation:
Points to remember
Area of circle = πr²
Where r is the radius of circle
Area of square = a²
Where 'a' is the side length of square
<u>To find the area of circle</u>
Here r = 10 cinches
Area = πr²
= 3.14 * 10²
= 3.14 * 100 = 314
<u>To find the area of square</u>
Here a = 20 inches
Area = a²
= 20²
= 400
<u>To find the probability percentage</u>
Probability = area of circle/Area of square
= (314/400)*100
78.5 %
The answer is 4/5, you can draw a model and compare and see or the easiest way is to write the fraction like this. And multiply cross way, 3 x 4 = 12 and 5 x 2 = 10, so write 12 on top of 4/5 and 10 on top of 2/5. So as you can tell, 4/5 is bigger than 2/3. Sorry for long explanation, it would be easier if I talked to you.

Let's find the percent increase with the help of formula:
Answer:
A bicentennial is defined as the 200th anniversary of a significant event.
Step-by-step explanation:
You replace the p in the given expression by -2 and the m by 3 and simplify
So its (-2)^ / 4 - 3
= 4/4 - 3
= 1 - 3 (note the division 4/4 is done first according to the order of operations rule)
= -2 answer
