Answer:
(b = 23 + a) and (a = 23 + b) = ab = 23 + ba
Step-by-step explanation:
-3k is the answer. -3 * k is an answer but it is not simplified. The simplified version is -3k.
Answer:
about 65 percentage is the correct answer
I think it is gonna be 320 because the others don’t make sense
In order to do this question you will need to find the area of both the square and the circle.
Area of Square:
If the circle is of the same width as the square, it means that the width of the square will be twice the radius of the circle
Width of Square = 8*2
=16
In a square, width= height
and area is calculated by multiplying width by height...
Therefore the area of the square is 16*16
= 256
Area of Circle:The formula to find the area of a circle is pi *r squared
Therefore area of circle = pi * 8^2
=201.06
Probability:You want to figure out what the probability of the dart hitting the circle is. In order to do this you have to calculate the percentage of the circle that takes up the square( which will give you your probability).
201.06/256 *100
=78.54 %
Therefore the answer is D
