please educated people solve my question i have reposted for the 4th time now...

Answer:

x = 130°

y = 50°

Step-by-step explanation:

x = 130° (Exterior alternate angles)

x + y = 180° (Angles in linear pair)

y = 180° - x

y = 180°- 130°

y = 50°

The solution to the problem in the figure attached in the question is: x = 130°, y = 50°

Alternate angles are angles that are formed in a situation whereby a line intersects two other lines, which lie on opposite sides of a transverse line and on contrasting proximate sides of the other lines.

From the given figure:

Angle x is an alternate angle to angle 130°.

Thus, x = 130°

Using the sum of angles on a straight line:

x + y = 180°

130° + y = 180°

y = 180° - 130°

y = 50°

Answer:

the first one

4a + 3a =7a

the second one

4a+4b

Answer:

1.  7a

2. 4a + 4b

Step-by-step explanation

1. (a x 4) = 4a

(a x 3) = 3a

4a + 3a = 7a

2. question 2 is correct

Isosceles triangle: It has two angles that have the same measure, i.e. the angle opposite the side of the same length

ΔXYA

∠Y=180° - (65+65) = 50°

ΔAYZ

∠Y=(180°-62°):2 = 59°

so ∠XYZ = 50°+59°=109°

[tex] {73.33ft}^{3} [/tex]

Step-by-step explanation:

[tex]v = \pi {r}^{2} \frac{h}{3} [/tex]

[tex]\pi {r}^{2} = {22ft}^{2} [/tex]

[tex]v = 22 \times \frac{10}{3} [/tex]

[tex]v = 22 \times 3.33[/tex]

[tex]v = {73.33ft}^{3} [/tex]

Step-by-step explanation:

so, we first put 10 in for x :

y = 6.50×10 + 50 = 65 + 50 = $115

and then we put 20 in for x :

y = 6.50×20 + 50 = 130 + 50 = $180

so, the ordered pairs are

(10, 115) and (20, 180)

Answer:

The second one between 2 and 3

Step-by-step explanation:

Sq root of 7 = 2.65

Answer:

2nd number line represents √7 best

Step-by-step explanation:

Method 1

√7 ≈ 2.65

Therefore, the 2nd number line represents √7 best

(the one with the dot between 2 and 3)

Method 2

√1 = 1

√4 = 2

√9 = 3

Therefore, as √7 is between √4 and √9, the solution is somewhere between 2 and 3.

Step-by-step explanation:

The area of a cube-shaped present in a box Lainley wraps is A. 81 in²

A cuboid is a three-dimensional closed figure which has volume along with surface area.

The volume of a cuboid is the product of its length, width, and height.

The total surface area of a cuboid is 2(lw + wh + wl) and the lateral surface area is 2(l + w)×h.

Given, A box that has a volume of 729 inches.

First we'll prime factorize 729.

729 = 3×243 = 3×3×81 = 3×3×3×3×3×3.

If we take the cube root of 729 it would be 3×3 = 9.

So, It is a cube with a side length 9.

Now, We know area of a cube is side².

Therefore, The area of this cube is 9² = 81 in².

Answer:

81 cm²

Step-by-step explanation:

Start by finding the perimeter of a rectangle.

[tex]Perimeter = 2(l+w)[/tex]

Plug in the given values into the equation:

[tex]Perimeter=2(14+4)=2(18)=36\ cm[/tex]

Since the perimeter of a square is:

[tex]Perimeter = 4s[/tex]

We can plug 36 cm in for the perimeter to solve for s

[tex]36\ cm=4s[/tex]

Divide both sides by 4

[tex]s=9\ cm[/tex]

The area of a square is:

[tex]Area=s^2[/tex]

Plug in the 9 cm for s

[tex]Area=9^2=81 \ cm^2[/tex]

3x+13=3(x+6)+1
Expand:

3x+13=3x+18+1
Simplify:

3x+13=3x+19
Subtract 13 from both sides:
3x+13-13=3x+19-13
Simplify:

3x=3x+6

Subtract 3x from both sides:
3x-3x=3x-3x+6

0=6

Since the sides are not equal there are no solutions to this problem

The value of the given expression is -15 - 3y

In maths, when there are terms in the bracket, it means we are to multiply the terms in the brackets by each other. This means that 5 + y would be multiplied by -3.

Multiplication is the process of determining the product of a set of numbers.

(5 + y)(–3) = -15 - 3y

Answer:

if m∠1 = 30° then m∠3 = 30° as they are parallel to each other and that is why they will have same angles.

therefore m∠3 = 30°

extra's:

→ m∠2 = m∠4 =

→ (360-30*20)/2

→ 150°

...............................

See here

m<1 and m<3 are opposite angles to eachother.

And we know that opposite angles are equal
