Answer:
The area of the regular nonagon is 7921.8 square inches.
Step-by-step explanation:
Geometrically speaking, the area of a regular polygon is determined by following area formula:
(1)
Where:
- Area of the regular polygon, in square inches.
- Perimeter, in inches.
- Apothem, in inches.
If we know that 
and 
, then the area of the regular nonagon is:
The area of the regular nonagon is 7921.8 square inches.
Answer brother this not maths question
Step-by-step explanation:
Answer:
The additive inverse of the polynomial being subtracted is -0.612-8+181
Step-by-step explanation:
Given expression : (1.32 +0.412 – 241) – (0.612 + 8 - 181)
Now the polynomial being subtracted : (0.612 + 8 - 181)
Additive inverse : The number in the set of real numbers that when added to a given number will give zero.
So, Additive inverse of 0.612 = -0.612
Additive inverse of 8 = -8
Additive inverse of -181 = 181
So, The additive inverse of polynomial being subtracted : -0.612-8+181
So, Option B is true
Hence the additive inverse of the polynomial being subtracted is -0.612-8+181
Answer:
this other dudes answer don’t make any sense
Answer: 90
Step-by-step explanation: The mean of a data set is equal to the
sum of the set of numbers divided by how many numbers are in the set.
So to find the mean of the data set
shown here, begin by adding the numbers.
Adding the numbers, we get 720.
This will be divided by the number of numbers in the set, or 8.
So we have 720/8 or 90.
So the mean of the data set shown here is 90.
