Answer:
C
Step-by-step explanation:
We want to find the total, which is 15. This crosses out A and B.
Also there are 3 x that makes a total of 15, (3x is x copied 3 times, not 3 + x), this crosses out D.
The only option left is C.
Answer: The result of the division is the number pi.
And the approximation of pi is: pi = 3.14
Step-by-step explanation:
The distance around a circle is called the perimeter of the circle.
The distance across a circle (This is a line that starts on one point of the circle, go through the center of the circle, and end in the next time it intersects the circle) is called the diameter of the circle.
The quotient between these two quantities is maybe one of the most famous numbers in the world, is the number pi, written as:
π = 3.14159265358979...
Is an irrational number, which means that the decimals keep going infinitely.
Then we can conclude that:
"The result of dividing the perimeter by the diameter, is equal to the number pi = π = 3.14159265358979..."
Because this is an irrational number and is actually impossible to write it, we usually use pi = 3.14 to aproximate it.
The rule for a rotation by 180° about the origin is (x,y) -->(−x,−y)
So A(-3, 2) to A'(3, -2)
Answer:
A'(3, -2)
Answer:
441 square feet.
Step-by-step explanation:
Area = length times width. Both length and width are 21 feet (3×7).
