Answer:

The coordinates of the flower bed are ([tex]-\frac{1}{3}[/tex] , 3)

Step-by-step explanation:

To find the centroid of a triangle, use this rule centroid = ([tex]\frac{x1+x2+x3}{3},\frac{y1+y2+y3}{3}[/tex]), where (x1, y1), (x2, y2), (x3, y3) are the vertices of the triangle

∵ The vertices of the triangle are (1, 1), (1, 4), (-3, 4)

∴ x1 = 1 and y1 = 1

∴ x2 = 1 and y2 = 4

∴ x3 = -3 and y3 = 4

→ Substitute them in the rule above

∵ Centroid = ([tex]\frac{1+1+-3}{3},\frac{1+4+4}{3}[/tex])

∴ Centroid = ([tex]\frac{-1}{3},\frac{9}{3}[/tex])

∴ Centroid = ([tex]-\frac{1}{3}[/tex] , 3)

∴ The coordinates of the flower bed are ([tex]-\frac{1}{3}[/tex] , 3)

Answer:

(2, 1 )

Step-by-step explanation:

Given the 2 equations

2x - y = 3 → (1)

x + y = 3 → (2)

Rearrange (2) expressing y in terms of x by subtracting x from both sides

y = 3 - x → (3)

Substitute y = 3 - x into (1)

2x - (3 - x) = 3

2x - 3 + x = 3

3x - 3 = 3 ( add 3 to both sides )

3x = 6 ( divide both sides by 3 )

x = 2

substitute x = 2 into (3) for corresponding value of y

y = 3 - 2 = 1

Solution is (2, 1 )

Step-by-step explanation:

The given ΔABC is an equilateral triangle because all the sides are equal. The term which does not describe the ΔABC is obtuse option D is correct.

Triangle is a shape made of three sides in a two-dimensional plane. the sum of the three angles is 180 degrees.

Given that:-

In AABC AB = 3x - 2, BC=x+4, and AC = 7. Also AB = BC

We know that AB = BC

3x - 2 = x + 4

3x = x + 4 + 2

3x = x + 6

2x = 6

x = 3

AB =  3x - 2 = 3(3) - 2 = 7

BC = x + 4 = 3 + 4 = 7

All three sides are equal so the triangle is an equilateral triangle. Hence given ΔABC is an equilateral triangle because all the sides are equal. The term which does not describe the ΔABC is obtuse option D is correct.

Answer:

x = 49

Step-by-step explanation:

The sum of angles in a triangle add up to 180°.

∠CBA = ∠EBD (Vertically opposite angles are equal)

          = 52°

Since in the triangle DBE, you already know two of the angles, you can find ∠BDE which is equal to ∠CAB (x + 9)°.

∠BDE = 180° - 70° - 52°

          = 58°

∠BDE = ∠CAB

          = ∠(x + 9)°

          = 58°

x + 9 = 58

x = 58 - 9

x = 49

Answer:

61 is the mean and the range is 19

Step-by-step explanation:

trust

Mean = [tex]60.1[/tex] and Range = [tex]19[/tex]  for the given set of data.

"Mean is the average set of all the given values."

"Range is the difference between highest and the lowest value."

Formula

Mean = [tex]\frac{Sum of all the observations}{Total number of observations}[/tex]

Therefore, Mean = [tex]\frac{49 + 50 +52 +58 +61 +63 +66 +67 +67 +68}{10}[/tex]

                            = [tex]\frac{601}{10}[/tex]

                            = [tex]60.1[/tex]

Range = Max (x) - Min (x)

            =  [tex]68 - 49[/tex]

            = [tex]19[/tex]

Hence, the Mean = [tex]60.1[/tex] and Range = [tex]19[/tex] for the given data set.

Step-by-step explanation:

We use the Pythagorean theorem.

a^2 + b^2 = c^2

13^2 = 169

Since 193 is not equal to 169, the triangle is not a right triangle.
