Which addition does the model below represent?
1 answer:
<h3>Answer:</h3>
[C] 3 + ( - 4).
<h3>Explanation:</h3>- First the arrow begins at 0 and moves to the right 3 spaces positive, ending at 3.
- Then it moves backwards, which is subtracting left 4 spaces towards -1 past zero.
- When adding a negative to a positive, you convert it to subtraction.
- 3 + -4 is the same as 3 - 4.
<u>Correct choice</u> - [C] 3 + (- 4).
<u>Note</u>: See the picture attached.

What is circle ?
A circle is a spherical shape without boundaries or edges.
A circle is a closed, curved object with two dimensions in geometry.
Consider two small arcs AB and CD of two circles of radii x and y units, both of which make an angle of measure θ at the centers P and Q respectively.
For smaller values of θ, the arc length AB is almost equal to the length of the line segment . Similarly, arc CD ≅
.
Using the SAS rule of triangle similarity, we can say that APB and CQD are similar triangles because their angles are the same and their ratios are AP: PB = CQ: QD = 1: 1. So, it stands to reason that AB: AP = CD: CQ.
Circumference = diameter or circumference = 2
radius if this constant equals some value.
So it was proved.
