Given:

Vertices of a triangle ABC are A(-3,0), B(3,0) and C(0,4).

To find:

The intersection point of all the medians of the triangle ABC.

Solution:

We know that, intersection point of all the medians of a triangle is called centroid.

The formula of centroid is

Centroid=\left(\dfrac{x_1+x_2+x_3}{3},\dfrac{y_1+y_2+y_3}{3}\right)

Vertices of a triangle ABC are A(-3,0), B(3,0) and C(0,4).

Centroid=\left(\dfrac{-3+3+0}{3},\dfrac{0+0+4}{3}\right)

Centroid=\left(\dfrac{0}{3},\dfrac{4}{3}\right)

Centroid=\left(0,1.333...\right)

Round each coordinate to the nearest tenth.

Centroid=\left(0,1.3\right)

The coordinates of required point are (0,1.3). Therefore, the correct option is C.

Someone please help me
pentagon [3]

Answer:

Option 3 or Option 4.

Step-by-step explanation:

I have this doubt because actually, a rhombus with a right angle (one) is not necessarily a square. Some rhombuses have one right angle and are still not squares. Now, if the four angles are right, it is a square, but this only says one.

On other hand, a parallelogram with congruent diagonals isn't a square necessarily either. Rectangles have congruent diagonals and are parallelograms.

In case you only can answer with one, I'll say is option 3, hope it helps!

What is One fourth of 12
Ulleksa [173]

Answer:

3

Step-by-step explanation:

We can start by writing one fourth as a fraction

1/4

Then we multiply it by 12.

1/4*12

This also means 12 divided by 4 which is 3.
