All internal angles in a quadrilateral add to 360

so
x+110+110+70=360
x+290=360
minus 290 both sides
x=70 degrees

St lies on the coordinate plane with s located at (3.2). The midpoint of dt is z(3,9) state the location of the endpoint T thank

77julia77 [94]

Answer:

T = (3,16)

Step-by-step explanation:

The midpoint formula is just another version of the pythagorean theorem, and it states that the midpoint between (x1,y1) and (x2,y2) is $\left(\frac{x_1+x_2}{2}\right),\:\left(\frac{y_1+y_2}{2}\right)$

Substituting what we know:

endpoint S is (3,2) and endpoint T is (x2,y2)

Midpoint Z is (3,9). We will apply the formula -- backwards.

$\left(\frac{3+x_2}{2}\right)=3$ , solving with algebra we get x2 = 3

So the x-coordinate of endpoint T is 3.

$\left(\frac{2+y_2}{2}\right)=9\quad$ , solving with algebra, we get y2 = 16.

So the y-coordinate of endpoint T is 16.

So the location of endpoint T is (3,16)

Sue Brown is a salesperson at a car dealership. She earned a gross pay of $8000 for the month of June. Her state tax rate is 3.5

Lera25 [3.4K]

Sue Brown owe $280.00 in state taxes for the month. Option B is correct.

Step-by-step explanation:

Gross pay for June= $8000

State tax rate = 3.5%

We need to find how much will Sue Brown owe in state taxes for the month.

We need to find 3.5% of 8000

Solving:

$3.5\% \,\,of\,\,800\\=\frac{3.5}{100}*8000\\=280$

So, Sue Brown owe $280.00 in state taxes for the month.

Option B is correct.

How many non-congruent triangles can be formed by connecting 3 of the vertices of the cube?

alexira [117]

Answer:

The number of non-congruent triangles that can be formed by connecting 3 of the vertices of the cube is 3 non-congruent triangles

Step-by-step explanation:

From the three dimensional shape of a cube, triangles can be constructed from;

1) 6 side faces

2) 4 front face to opposite vertices triangles

3) 4 rear face to opposite vertices triangles

Each face can produce ₄C₃ = 4 triangles

Therefore;

The total number of triangles that can be formed = 4 × 6 + 4 × 4 + 4 × 4 = 56 triangles

Of the 56 triangles, it will be found that all 24 triangles from the different 6 direct faces will have the same dimension of 1, 1, √2 are congruent

The 24 triangles formed by the sides of the faces and an adjacent diagonal have the same dimension of 1, √2, √3 and are congruent

The 8 triangles formed by joining the three diagonals have the same dimension of √2, √2, √2 are congruent

Therefore, the 56 triangles comprises of a combination of three non-congruent triangle.

There are only 3 observed non congruent triangles formed by connecting three of the vertices of the cube.

The high school band is selling wrapping paper. It costs $4 each week to advertise the wrapping paper. The band buys each roll o

Setler79 [48]

For this case, the first thing we must do is define variables:
x: rolls of wrapping paper in one week
We now write the equation that models the profit of the band.
We have then:
P (x) = (3.50 - 2) x - 4
P (x) = 1.50x - 4
Answer:
An equation to model the amount of profit, P, the band makes from x rolls of wrapping paper in one week is:
P (x) = 1.50x - 4
