Answer:

15y

Step-by-step explanation:

first the 2 can cancel:

[tex]\frac{2x}{2y} =16[/tex]

turns into:

[tex]\frac{x}{y} =16[/tex]

now since we need to find x-y,

x=16y

16y-y=15y

Answer:

The door is not in rectangle shape.

Step-by-step explanation:

Given:

Length of base = 30 inches

Height of door = 84 inches

Diagonal of door = 91 inches

Find:

The door is rectangle or not

Computation:

Using Pythagorean theorem

Hypotenuse² = Perpendicular² + Base²

So,

91² = 84² + 30²

8,281 = 7,056 + 900

8,281 ≠ 7,956

So we say that the given door angle is not 90°

So,

The door is not in rectangle shape.

The Coordinates for point A and B are as follows:

A                                 B

 1                                  2

 2                                 4

 3                                 6

A coordinate system is a method for identifying the location of a point on the earth. Most coordinate systems use two numbers, a coordinate, to identify the location of a point.

The Coordinates for point A and B are as follows:

A                                 B

 1                                  2

 2                                 4

 3                                 6

 4                                 8

 5                                 10

 6                                 12

 7                                  14

 8                                  16

 9                                  18

 10                                20

Thus, y-coordinates are double than x-coordinates.

Answer:

Parallel lines are lines in the same plane that do not intersect, like lines on notebook paper.

The "in the same plane" requirement is important!  Take a look at the attached image.  Lines AD and DC don't intersect, but they are not in the same plane (face of the rectangular solid).  We don't call those parallel, we call them skew lines.

Answer:

since the radius is 11 witch the radius is only half so times by 2 witch would be the diamater witch is 22 so the area would be A≈381

Step-by-step explanation:

A=14πd2=14 · π · 222 ≈ 381

i think thats it bc If the object is a circle, and you know its circumference, you would divide the circumference by pi to find the diameter of the circle. Half the diameter is the radius. Square the radius and multiply by pi to find the area of the circle.

Answer:  She paid $66.33

Step-by-step explanation:

The overall amount that you paid for the video game was 87.95. She got 27.79 back as a refund. So you subtract what she paid from her refund. 87.95-27.79 = 60.16.  She also had to pay a fine for the video game. So you add the fine to the amount. 60.16+6.17 = 66.33.

Overall, she paid 66.33.

Answer:

It's $66.33

Step-by-step explanation:

87.95-27.79+6.17=66.33

↓

She first bought electronics worth of $87.95.

Returned a video game and received a refund of $27.79.

=60.16 (87.95-27.79) | You have to subtract.

Had to pay a fee of $6.17 after returning the video game.

final amount - $66.33 (60.16+6.17) | You have to add the amount she now had after she got the refund and the restocking fee she had to pay.

The value of x is 35 degrees, as it is opposite to the other 35 degree angle. Now, to find y. We can see by the indicators that the measure of the y angles are equal. These angles, along with the 35 degree angle that is indicated are in a straight angle. This helps us. Form an equation.

2y+35=180

2y+35-35=180-35

2y=145

y=72.5

Therefore, the value of the x angle is 35 degrees and the value of the y angle is 72.5 degrees.

Step-by-step explanation:

1.

Area of a parallelogram = base × height

The area of the parallelogram

= 2.7 × 1.2

= 3.24 m²

2.

Try to divide the figure into 2 rectangles and find their areas.

The area of the larger rectangle

= 6 × (20-6)

= 84 cm²

The area of the smaller rectangle

= 12 × 6

= 72 cm²

The total area of the figure

= 84 + 72

= 156 cm²

Answer:

C) 3.24m^2

C) 156 cm^2

Step-by-step explanation:

The area of a parallelogram is base * height.

The base is 2.7m, while the height is 1.2m.

2.7*1.2 = 3.24m^2.

We can envision the area of the figure to be a rectangle with another rectangle cut out of it.

The total rectangle's area is 20*12, which equals 240cm^2.

The smaller rectangle's width would be 12 - 6, which is 6. The length would be 20 - 6, which is 14. 6 * 14 = 84.

Now we just have to subtract 84. from 240, which is simple. 240-84=156.

The answer is 156cm^2.

Answer:

1. a = 5, b = 8

2. d = 2

Step-by-step explanation:

1. The sum of adjacent angle is 180 degree

115 + 8b +1 = 180

8b = 180 -116

b = 8

Similarly

14a - 5 + 115 = 180

14a = 180 -110

14a = 70

a = 14

2. Intersecting diagonals divide each other into equal halves

Answer: 2,-6

Step-by-step explanation:

The vertex of the parabola defined by the equation x² - 4x + y + 10 = 0 is (2, -6).

To maintain the equality of the equation, we need to add and subtract 4 within the parentheses.

3. Rewrite the equation by adding and subtracting 4 within the parentheses: x² - 4x + 4 + y = -10 + 4.

Now, we can factor the perfect square trinomial (x - 2)² and simplify the right side of the equation.

4. Factor the perfect square trinomial: (x - 2)² + y = -6.

The equation is now in the form (x - h)² + k = y, where (h, k) represents the vertex of the parabola. Therefore, the vertex of the parabola is (2, -6).
