Answer:

Diameter of the roll after the decrease = 2.54 inches

Step-by-step explanation:

Circumference of a roll of party streamers = 11 inches

Circumference of the circle is given by = 2π × radius

Now, circumference of the streamers is decreased by 3 inches

⇒ Decreased circumference of the streamers = 11 - 3 = 8 inches

To find radius of the decreased circumference streamers :

2π × radius = 8

⇒ Radius = 1.27 inches

Hence, Diameter of the roll after the decrease = 2 × 1.27

                                                                                 = 2.54 inches

The Midpoint of AB dkdldl
Nutka1998 [239]
  • The Midpoint of AB is (1,0).

Given that:

  • In line AB, where the coordinates of A is (3,1) and coordinates of B is (-1,-1).

To find:

  • The Midpoint of line AB.

So, according the question

We know that,

The midpoint M of a line segment AB with endpoints A (x₁, y₁) and B (x₂, y₂) has the coordinates M ( \frac{x_1 + x_2}{2} , \frac{y_1 + y_2}{2} ).

Now from question,

We know that the the coordinates of A is (3,1) and coordinates of B is (-1,-1) of line AB.

So, we can say that

   A is (3,1) or x₁ = 3 and y₁ = 1.

   B (-1,-1) or x₂ = -1 and y₂ = -1.

∵ The coordinates of midpoint M (X,Y)

          X = \frac{x_1 + x_2}{2}

              = \frac{3-1}{2}

              = 2/2

          X = 1.

And

          Y = \frac{y_1 + y_2}{2}

              = \frac{1-1}{2}

              = 0/2

          Y = 0.

So, the midpoint of line AB is M (1,0)
