Answer:

[tex]m\angle 1 = 40^\circ[/tex]

Step-by-step explanation:

First, notice that the two lines are parallel as indicated by the arrow.

Therefore, by the Alternate Interior Angles Theorem:

[tex]\angle 1\cong \angle 2[/tex]

So:

[tex]m\angle 1 = m\angle 2[/tex]

Substitute:

[tex](2x+20)=(3x+10)[/tex]

Solve for x. Subtract 2x from both sides:

[tex]20=x+10[/tex]

And subtract 10 from both sides:

[tex]x=10[/tex]

We know that:

[tex]m\angle 1 = 2x+20[/tex]

Substitute. Hence:

[tex]m\angle 1 =2(10)+20=40^\circ[/tex]

Answer:

3rd one down is the answer

Answer:

Well let's count how many 65's there are, there are 3

So there needs to be 3 dots on the data plot on top of the section, 65.

Let's exclude some answers, D and B since they don't have 3 hovering over the 65(since there are three 65's).

Let's count how many 67's there are, there are 4.

We need to get rid of any answers that are more than 4 or less than 4 that are hovering over the section of 67. There are no answers to get rid of, let's move onto the next number, 68! There are four 68's. Let's also get rid of any answers that have more than 4 or less than 4 on the section above 68 since we're looking at that number. C is our answer!

Answer:

If the terms on the left hand side of the equals are the same as the terms on the right hand side of the equals, there will be infinite solutions

Step-by-step explanation:

If the terms on the left hand side of the equals are the same as the terms on the right hand side of the equals, there will be infinite solutions

12x+24x +18 = 36x +24 -6

Combining like terms

36x+18 = 36x +18

Subtracting 36x from each side

18 = 18

This is always true so  it does not matter what x is, the left had side will equal the right hand side

Answer:

A = 14 units^2

Step-by-step explanation:

The figure is a triangle

Answer:

Died speciman prior would be best to measure the bird’s mass.The length (also bill-to-tail length) of a bird is usually measured from dead specimens prior to their being skinned for preservation. The measurement is made by laying the bird on its back and flattening out the head and neck gently and measuring between the tip of the bill and the tip of the tail.

Answer:

1 and 2 are equivalent

For 1 , use distributive property. Distribute 5 to a and 3. 5 x a = 5a, and 5 x 3 = 15. Therefore, 5a + 15. This is why 1 is equivalent to number 2.

Given:

In triangle HIJ, N is the centroid and [tex]HK=10[/tex].

To find:

The value of KI.

Solution:

In a triangle, the centroid of the triangle is the intersection of its medians.

Median of a triangle from a vertex divides the opposite side into two equal parts.

It is given that, N is the centroid. It means JK, HL and IM are the medians of the triangle HIJ.

Since JK is a median of the triangle HIJ, therefore it divides the opposite side IH into two equal parts.

[tex]KI=HK[/tex]

[tex]KI=10[/tex]

Therefore, the value of KI is 10 units.

Answer:

3.50

Step-by-step explanation:

Necklace has beads and a pendant

b +p

There are 6 necklaces at a cost pf 43.80

6(b+p) =43.80

The beads for one necklace cost 3.80 so replace b with 3.80

6(3.80+p) =43.80

Divide each side by 6

6(3.80+p)/6 =43.80/6

3.80 +p = 7.30

Subtract 3.80 from each side

3.80+p-3.80 = 7.30 -3.80

p =3.50

Answer:

(p,r) = (1/3, 2/9)

Step-by-step explanation:

Here, we want to solve a system of equations

We can rewrite the second equation by dividing through by 2

So we have;

4p + 3r = 2

and

5p - 3r = 1

Add both equations:

9p = 3

p = 3/9

p = 1/3

Recall ;

5p - 3r = 1

3r = 5p - 1

Substitute the value or p here

3r = 5(1/3)-1

3r = 5/3 - 1

3r = 2/3

r = 2/9

So we have the solution set as;

(p,r) = (1/3 , 2/9)

Answer:

Cada garrafa tiene una capacidad de 24 litros.

Step-by-step explanation:

Tenemos dos garrafas, definamos V como el volumen que cada garrafa tiene.

Sabemos que una de las garrafas tiene el 20%, entonces el volumen de agua que tiene esta garrafa es:

(20%/100%)*V

Y la otra garrafa tiene el 30%, entonces esta garrafa tiene:

(30%/100%)*V

El volumen total de agua es la suma de esos dos volúmenes, que nos da:

(20%/100%)*V + (30%/100%)*V

Y sabemos que tenemos 12 L de agua, entonces podemos escribir la ecuación:

12 L = (20%/100%)*V + (30%/100%)*V

Ahora podemos resolver esto para V.

12L = 0.2*V + 0.3*V

12L = 0.5*V

12L/0.5 = V

24L = V

Cada garrafa tiene una capacidad de 24 litros.

Answer:

Volume of sphere = 44.57 cm³

Step-by-step explanation:

Given:

Diameter of sphere = 4.4 centimeter

Value of π = 3.14

Find:

Volume of sphere

Computation:

Radius of sphere = Diameter of sphere / 2

Radius of sphere = 4.4 / 2

Radius of sphere = 2.2 centimeter

Volume of sphere = [4/3][π][r³]

Volume of sphere = [4/3][3.14][2.2³]

Volume of sphere = [4/3][3.14][10.648]

Volume of sphere = [1.333][3.14][10.648]

Volume of sphere = 44.568

Volume of sphere = 44.57 cm³

Answer:

180 degrees

Step-by-step explanation:

East and west are two opposite directrions along the same line.

The angle is 180 degrees.

Answer: 180°

Step-by-step explanation: The directions on a compass would look something like this; (Refer to the image.)

A full circle is 360°. Half of 360 is 180. You would have to make a clockwise rotation by 180° to face West. Think of this picture as a clock or a circle.

I hope this helps!

Answer: 153.94

Step-by-step explanation: Formula for area of a circle: pi * r^2

First find the radius by dividing the diameter by 2: 14/2 = 7

Then plug the radius, 7, and pi, 3.14, into the formula:

(3.14) * (7^2) = 153.94 inches squared

[tex]x=\frac{-7±\sqrt{5 } }{2}[/tex]

Step-by-step explanation:

4x² + 28x + 49 = 5

4x² + 28x + 49 - 5 = 0

4x² + 28x + 44 = 0

4(x² + 7x + 11) = 0

4(x² + 7x + 11) ÷ 4 = 0 ÷ 4

x² + 7x + 11 = 0

[tex]x=\frac{-b±\sqrt{b^{2}-4ac } }{2a}[/tex]

Ignore the A before the ±. It wouldn't let me type it correctly.

a = 1

b = 7

c = 11

[tex]x=\frac{-7±\sqrt{7^{2}-4((1)(11)) } }{2(1)}[/tex]

[tex]x=\frac{-7±\sqrt{49-4((1)(11)) } }{2(1)}[/tex]

[tex]x=\frac{-7±\sqrt{49-44 } }{2(1)}[/tex]

Answer:

No, the poster would not fit in the frame

Step-by-step explanation:

A rectangle is a quadrilateral (has 4 sides and 4 angles) with two pair of opposite and equal sides.

A square is a quadrilateral in which all sides are equal.

Given that the rectangular frame has a width of 40 inches and a length of 30 inches. The area of the rectangular frame is:

Area of rectangular frame = length * breadth = 40 inches * 30 inches = 1200 in²

Since the square frame has the same area as the rectangular frame, hence:

Area of square frame = length * length

length² = 1200

length = √1200 = 34.64

Therefore the dimensions of the square frame is 34.64 inches by 34.64 inches.

Hence a poster with dimensions of 36 inches X 36 inches cannot fit in the square frame.

Answer:

34

Step-by-step explanation:

the two angles u know add up to 148 and a full angle is 180 so 180-148 gives u 34
