Since, the number w and 0.8 are additive inverses.
A number 'a' is said to have an additive inverse '-a' if "a+ (-a)= 0".
Since, 'w' and '0.8' are additive inverses of each other such that 
Therefore, the value of 'w' should be '-0.8' so that
.
So, the value of 'w' is =0.8
Now, Refer to the attached image which represents the position of 0.8 , w ( that is -0.8) and the sum of 0.8 and w.
Sum of 0.8 and w = 0.8 + w
= 0.8 +(-0.8)
= 0.
What is the question?
I'm assuming it is to find the length and width.
+_= plus or minus

Answer:
The approximate length of arc s is 14.1 inches
Step-by-step explanation:
<u><em>The picture of the question in the attached figure</em></u>
step 1
Find the circumference of the circle
The formula to calculate the circumference is equal to

we have

substitute

step 2
Find the approximate length of arc s
we know that
The circumference of a circle subtends a central angle of 360 degrees
so
using proportion
Find the arc length s for a central angle of 135 degrees

Answer:
12 squares
Step-by-step explanation:
Data provided:
Dimension of the rectangle = 30 × 40
Area of the rectangle = 30 × 40 = 1200
Dimension of the area to be divided = 10 × 10
Thus,
Area of the square to be divided into = 100
Therefore,
The number of square in which it can be divided
=
=
= 12
Hence,
It can be divided in 12 squares
