is 13/7 a rational number? how do you know?

Answer:

-2

Step-by-step explanation:

Answer:

-2 the other person is also definitely right.

Step-by-step explanation:

If there are two straight lines the opposite angles equal each other

so 4x+2=150

subtract both sides by 2

4x=148

divide both sides by 4

x=37

Hope that helps :)

Answer:

35x² + 29x - 30

Step-by-step explanation:

Given

25x² + (5x - 3)(2x + 7) - 9 ← expand factors using FOIL

= 25x² + 10x² + 29x - 21 - 9 ← collect like terms

= 35x² + 29x - 30

Answer:

m∠XZY = 122°

m∠XWY = 61°

Step-by-step explanation:

From the picture attached,

A circle has been given with center as Z.

∠XZY is a central angles subtended by the arc XY,

Therefore, measure of angle XZY will be equal to measure of ∠XZY.

m(∠XZY) = m(arc XY) = 122°

By another property of the circle,

"Inscribed angle measures the half of the central angle intercepted by the same arc."

Therefore, m∠XWY = [tex]\frac{1}{2}(\angle XZY)[/tex]

                                 = [tex]\frac{1}{2}(122)[/tex]

                                 = 61°

Each spinner has 5 numbers, the total combinations would be 5 x 5 = 25 combinations,

The answer is 25

Answer:

336 ft^2

Step-by-step explanation:

All you have to do is find the area of each face, and add them up.

Firstly lets starts with the identical triangles.

There are two of them, and the area of a triangle is b*h/2

So the area is 6*8/2 , which is 24, and since their are two of them, we add another 24, and we get 48 so far.

Since all the other sides are rectangles, we can just multiply the given lengths and add them up.

So, we have

12x10, which is 120,

12x8, which is 96, and

12x6, which is 72.

Now add all of them up.

48+120+96+72 which is 336

Your answer is 336 ft^2

Answer:

45 degrees

Step-by-step explanation:

Each triangle in the figure is at a 45 degree angle to the next one, telling us that if you rotate the entire thing by 45 degrees, it will flip.

Answer:

B. 45 degrees

Step-by-step explanation:

The questions is asking us to find the minimun degrees needed to rotate the shape so that it maps itslef, which is just basically asking us to roate the shape so that it looks the same as it is now. That means that we need to rotate the shape so that another one of those traingles is pointing up. There are 8 of those traingle, and there is 360 degrees in a circle. So divide 360 degrees by 8, and we find that there is 45 degrees inbetween each of the triangles. So if we rotate it by 45 degrees the next traingle will be pointing up and the shape will have mapped itself.

Answer:

8y+9

Step-by-step explanation:

Answer:

6y + 44

Step-by-step explanation:

y + 4 + 5(y + 8)

y + 4 + 5y + 40

6y + 44

Answer:

≈ 29°

Step-by-step explanation:

Using calculator

[tex]cos^{-1}[/tex] [tex]\frac{7}{8}[/tex] ≈ 29° ( to the nearest degree )

Answer:

x = 22°

the angles are: 63° and 117°

Step-by-step explanation:

a linear pair of angles total together to be 180°

so:

3x - 3 + 5x + 7 = 180

combune like terms:

8x = 176

divide both sides of the equation by 8:

x = 22°

the angles are: 63° and 117°

Answer:

The length of the park is approximately 1.77 kilometers

Step-by-step explanation:

The law of cosines is most appropriate when the measures of two sides and the included angle formed n=by the path of motion is known

The given parameters of the question are;

The distance from Mark's house to the edge of the park, a = 0.9 km

The distance from the far side of the park to Mark's house, c = 1.6 km

Whereby the included angle between lines, 'a' and 'c' is the ∠B = 85°, by cosine rule, we have;

b² = a² + c² - 2·a·c·cos(B)

Where;

b = The length of the park in kilometers

By plugging in the known values of 'a', 'b', and 'c', we get;

b² = 0.9² + 1.6² - 2 × 0.9 × 1.6 × cos(85°) ≈ 3.11899146089

∴ b = √(3.11899146089) ≈ 1.76606666377

Therefore, the length of the park, b ≈ 1.77 km.

Answer:

C

Step-by-step explanation:

I did this by graphing the points on paper and then forming an equation from there. Another way is to do to slope equation. The slope equation is: [tex]m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}[/tex], so you would just fill it in here. (4+4) (I did PLUS since subtracting a negative is adding a postive number). This equals 8. (0-2) is -2, so 8/-2 is -4x. For the y-intercept, it is already shown in the equation. This is 4 because if x is 0, then that is the y-intercept. So: y=-4x+4.

Answer:

x= -1

Step-by-step explanation:

p= x² +4x -2 -----(1)

q= 2x -1 ------(2)

q -p= 2 -----(3)

Substitute (1) and (2) into (3):

2x -1 -(x² +4x -2)= 2

2x -1 -x² -4x +2= 2 (Expand bracket)

-x² -2x +1=2 (Simplify)

x² +2x +2 -1= 0 (Bring all terms to one side)

x² +2x +1= 0

(x +1)²= 0 (Factorise)

x +1= 0 (Square root both sides)

x= -1 (-1 on both sides)
