Answer:
Associative property - addition
Step-by-step explanation:
When three or more numbers are added, the sum is the same regardless of the way in which the numbers are grouped.
(6+2) + 5 = 6 + (2+5)
8 + 5 = 6 + 7
13 = 13
I would say the last one is B, because of you use a calculator you will see that the equation adds up to B. Also if you have any trouble with your math download the app Photomath. It changed my life! Hope this helps
Answer:
5π m
Step-by-step explanation:
Using the pythagorean theorem we can figure out that the third side is 5m
A^2 + B^2 = C^2
3^2 + 4^2 = C^2
9 + 16 = C^2
25 = C^2
√23 = √(C^2)
C = 5m
Side C is also the diameter of the circle, so the radius is 5/2, or 2.5
From that we can use the circumference formula, Circumference = 2π<em>r</em>
Circumference = 2 π (2.5) = <u>5π m</u>
To round to the nearest ten thousand, look at the number in that place. This number is 8. Now look at the number after it. It is less than five so keep the number as it is. This number rounded would be 780,000.
Here is a graph with the equation you gave graphed on it.
