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

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

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

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

[tex]Centroid=\left(\dfrac{0}{3},\dfrac{4}{3}\right)[/tex]

[tex]Centroid=\left(0,1.333...\right)[/tex]

Round each coordinate to the nearest tenth.

[tex]Centroid=\left(0,1.3\right)[/tex]

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

Answer: 3,4,5

Step-by-step explanation:

5² = 3² + 4²

25 = 9 + 16

25 = 25

The set of numbers 3, 4, and 5 describe the side length of a right triangle.

Option C is the correct answer.

Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

We have,

Set of numbers:

1, 2, 3

2, 3, 4

3, 4, 5

4, 5, 6

We need to find the set of numbers that describe the side length of a right triangle.

We will apply the Pythagorean theorem to all the sets of numbers.

Using 1,2,3.

1² = 2² + 3²

1 = 4 + 9

1 = 13

2² = 1² + 3²

4 = 1 + 9

4 = 10

3² = 1² + 2²

9 = 1 + 4

9 = 5

This is not true.

Similarly,

Set of numbers: 2,3,4 and 4,5,6 are not true.

Using 3, 4, 5

5² = 3² + 4²

25 = 9 + 16

25 = 25

This is true.

Thus,

The set of numbers 3, 4, and 5 describe the side length of a right triangle.

Option C is the correct answer.

Answer:

last one

Step-by-step explanation:

the last one because it cannot be expressed as a fraction.

Answer:

a. 73%

b. 73:100

c. 0.73

d. 73/100

Step-by-step explanation:

If you are only talking about the shaded part out of the total number of squares then these are your answers

73 out of 100 is 73%

73:100 is the ratio

73/100 = 0.73 is the decimal

73/100 is the fraction

Answer: $375.37

Step-by-step explanation:

From the question, we are told that Kelly has $5.38 in her account before receiving her $832.19 paycheck. We are further told that she writes checks for rent and car insurance in the amounts of $359.82 and $72.38 and that she also withdraws $30.

Her current balance will be:

= $5.38 + $832.19 - $359.82 - $72.38 - $30

= $375.37

Her current balance is $375.37

Answer:

5,15

Step-by-step explanation:

For mixed fractions, mutiply the bottom and add the top Ex: 1x4=4 and 4+1=5 hence 1 1/4 being 5/4 and the second you just mulitply. 3X5=15 4X5=20 or 15/20.

Answer:

s = 12cm

Step-by-step explanation:

Since these are similar triangles, in order to find a missing side, you have to find the constant of proportionality

14/8 = 21/s          >> cross multiply

14s = 168             >> divide both sides by 14 to get s alone

s = 12

another way to find the answer......

Step-by-step explanation:

You still have to find the constant of proportionality, it's just going to be a bit faster this way

14/8 = 1.75

21/1.75 = 12

s = 12

Answer:

The slope is [tex]m=-\frac{3}{2}[/tex]

Step-by-step explanation:

The slope point equation is given by:

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Here:

The first point is (x1,y1)=(5,-3)

The first point is (x2,y2)=(-1,6)

Then, the slope will be:

[tex]m=\frac{6-(-3)}{-1-5}[/tex]

[tex]m=\frac{9}{-6}[/tex]

[tex]m=-\frac{3}{2}[/tex]

Step-by-step explanation:

Answer: x = 3

Step-by-step explanation:

y for x

4 for 12

1 for ?

Cross multiply

4? = 12 x 1

4? = 12

Divide both sides by 4

? = 3

When y = 1, x = 3.

Answer:

y = -3x-2

Step-by-step explanation:

Well, the linear equation of a line is:  y = mx + b

Where m is the slope and b is your y-intercept

So, you can just plug the numbers into the equation

m = -3 and b = - 2

y = -3x - 2

Step-by-step explanation:

Mary spends 8*6=48 dollars

Pete spends 9*12=108

Mary got a better deal per cupcake

Answer:

They spent the same amount per cupcake ($1.33)

Step-by-step explanation:

To solve this, we need to find the unit rate of cost per cupcake. To do that, we divide 8 by 6 and divide 12 by 9. When we do that, we get 1.33 for both. That means they spent the same amount per cupcake ($1.33).
