How to get midpoint in a graph with 2 endpoints
Flura [38]

Answer:

You can find the midpoint of a line segment given 2 endpoints, (x1, y1) and (x2, y2). Add each x-coordinate and divide by 2 to find x of the midpoint. Add each y-coordinate and divide by 2 to find y of the midpoint. It's important to note that a midpoint is the middle point on a line segment.

In order to see the midpoint formula in use, let's look at an example.

Question:

Determine the midpoint of the line segment with the given endpoints.

A(3, 7), B(9, 1)A(3,7),B(9,1)

Solution:

We can use the formula for midpoint to determine the midpoint: M= (x1 + x2/2 , y1+y2/2)

First, plug the x and y value into the formula:

M=(3+9/2 , 7+1/2)

,

Then, we can calculate the midpoint:

(6, 4)

A triangular prism has base edges 2 cm, 6 cm, and 7 cm long. Its lateral area is 330 cm2. What is the height of the prism? cm. T
Ostrovityanka [42]

9514 1404 393

Answer:

  22 cm

Step-by-step explanation:

The lateral area is the product of the perimeter and the height. The perimeter is the sum of side lengths.

  P = a+b+c = (2 +6 +7) cm = 15 cm

  LA = Ph

  330 cm^2 = (15 cm)h . . . fill in the known values

  h = (330 cm^2)/(15 cm) = 22 cm

The height of the prism is 22 cm.

Can anyone help? Most brainiest for the correct answer!!
zhannawk [14.2K]
<h3>Answer:  25</h3>

Explanation:

The "large cars" pie slice takes up 7% of a full circle. This means that the degree measure of this slice takes up 7% of a full 360 revolution.

7% of 360 = 0.07*360 = 25.2 degrees

This then rounds to 25 degrees
