Answer:

2 hours and 45 minutes

Step-by-step explanation:

you add the 15 and 30 and then add 2 hours.

Ana spent 2 hours and 45 minutes working.

Unitary method is a technique used in mathematics to solve problems that involve proportional relationships. It involves finding a unit rate (i.e., a rate per unit) and using it to solve problems that involve different quantities of the same type of unit.

To find the amount of time Ana spent working, we need to subtract the starting time from the finishing time.

The starting time is 2:45 pm and the finishing time is 5:30 pm.

We can subtract the starting time from the finishing time as follows:

5:30 pm

2:45 pm

2:45 pm

So, Ana spent 2 hours and 45 minutes working.

Answer:

a. (x – 2)2 + y2 = 4

Step-by-step explanation:

edge 2021

The rectangular form of [tex]\mathbf{r = 4cos(\theta)}[/tex] is (a) [tex]\mathbf{(x - 2)^2 + y^2= 4}[/tex]

The polar coordinate is given as:

[tex]\mathbf{r = 4cos(\theta)}[/tex]

Multiply both sides of [tex]\mathbf{r = 4cos(\theta)}[/tex] by r

[tex]\mathbf{r \times r= 4cos(\theta) \times r}[/tex]

Evaluate

[tex]\mathbf{r^2= 4rcos(\theta) }[/tex]

As a general equation, we have:

[tex]\mathbf{x^2 + y^2 = r^2}[/tex]

Substitute [tex]\mathbf{x^2 + y^2 = r^2}[/tex] in [tex]\mathbf{r^2= 4rcos(\theta) }[/tex]

[tex]\mathbf{x^2 + y^2= 4rcos(\theta) }[/tex]

Also as a general equation, we have:

[tex]\mathbf{x = rcos(\theta)}[/tex]

So, [tex]\mathbf{x^2 + y^2= 4rcos(\theta) }[/tex] becomes

[tex]\mathbf{x^2 + y^2= 4x}[/tex]

Subtract 4x from both sides

[tex]\mathbf{x^2-4x + y^2= 0}[/tex]

Complete the square on x^2 - 4x

[tex]\mathbf{(x - 2)^2-2 + y^2= 0 + 2}[/tex]

Add 2 to both sides

[tex]\mathbf{(x - 2)^2 + y^2= 0 + 2+2}[/tex]

[tex]\mathbf{(x - 2)^2 + y^2= 4}[/tex]

Hence, the rectangular form of [tex]\mathbf{r = 4cos(\theta)}[/tex] is (a) [tex]\mathbf{(x - 2)^2 + y^2= 4}[/tex]

The new coordinate of vertex B if the triangle is dilated with a center at the origin by a scale factor of 1/3 is (1,2) and this can be determined by using the given data.

Given :

After the dilation of 1/3 the coordinate of the triangle becomes:

[tex]\rm A(-2,2) \to A'(-2\times \dfrac{1}{3},2\times \dfrac{1}{3}) = A'\left(\dfrac{-2}{3},\dfrac{2}{3}\right)[/tex]

[tex]\rm B(3,6) \to B'(3\times \dfrac{1}{3},6\times \dfrac{1}{3}) = B'\left(1,2)[/tex]

[tex]\rm C(1,-2) \to C'(1\times \dfrac{1}{3},-2\times \dfrac{1}{3}) = C'\left(\dfrac{1}{3},\dfrac{-2}{3}\right)[/tex]

The new coordinate of vertex B if the triangle is dilated with a center at the origin by a scale factor of 1/3 is (1,2).

Answer:

2340 units²

Step-by-step explanation:

The easiest way to solve for the area of the hexagon is to find the area of the rectangle and subtracting the area of the triangles from it.

First, find the area of the rectangle:

A(rectangle) = (15 + 30 + 15)(26 + 26)

A(rectangle) = (60)(52)

A(rectangle) = 3120

Next, find the area of the 4 triangles:

A(triangles) = 1/2(15)(26) · 4

A(triangles) = 195 · 4

A(triangles) = 780

Finally, subtract the two areas to find the area of the hexagon:

A(hexagon) = 3120 - 780

A(hexagon) = 2340

Based on the information given the area of hexagon is 2340.

First step is to find the area of the rectangle:

Area of rectangle= (15 + 30 + 15)(26 + 26)

Area of rectangle=60×52

Area of rectangle= 3120

Second step is to find the area of the 4  triangles:

Area of rectangle =[1/2(15)(26)]×4

Area of rectangle= 195 × 4

Area of rectangle= 780

Third step is to find the area of hexagon:

Area of hexagon= 3120 - 780

Area of hexagon=2340

Inconclusion  the area of hexagon is 2340.

Answer:

no solutions

Step-by-step explanation:

plug in y to x:

15x + 5(8 - 3x) = 20

15x + 40 - 15x = 20 ( you would subtract 15x from 15x.)

0 + 40 = 20

40 = 20

40 does not equal 20 so it would be no solutions.

Using substitution, the system above has no solutions.

Given  that,

Based on the above information, the calculation is as follows:

  Here we put the y value

15x + 5(8 - 3x) = 20

15x + 40 - 15x = 20  

0 + 40 = 20

40 = 20

Since 40 does not equal 20 so it would be no solutions.

Answer:

(2, - 1 )

Step-by-step explanation:

Given the 2 equations

y = 4x - 9 → (1)

y = x - 3 → (2)

Substitute y = 4x - 9 into (2)

4x - 9 = x - 3 ( subtract x from both sides )

3x - 9 = - 3 ( add 9 to both sides )

3x = 6 ( divide both sides by 3 )

x = 2

Substitute x = 2 into either of the 2 equations for y

Substituting into (2)

y = 2 - 3 = - 1

solution is (2, - 1 )

Answer:

The shape is a kite and x=26

Step-by-step explanation:

The shape is a kite because the two adjacent sides at the right match and the two sides on the left match

To find x:

125+125=250

360-250=110

(3x-11)+(2x-9)=110

Combine like terms: 5x-20=110

Add 20 to both sides: 5x-20+20=110+20

5x=130

Divide both sides by 5: 5x/5=130/5

x=26
