Answer:

50

Step-by-step explanation:

All angles around a circle is 360°

/_ 2 = 130°

/_ 1 = 130° (Vertically opposite angles)

= 130° + 130° = 260°

all angles = 360°

= 360° - 260° = 100°

= 100° ÷ 2

= 50°

= /_ 3 and /_ 4 = 50°

Verification = 130° + 130° + 50° + 50° = 360°

Answer:

x = 33

Step-by-step explanation:

x - 12 and 2x + 3 form a right angle , then

x - 12 + 2x + 3 = 90

3x - 9 = 90 ( add 9 to both sides )

3x = 99 ( divide both sides by 3 )

x = 33

Answer:

1 batch

Step-by-step explanation:

Farah needs 4 and 4/5 pounds of tomatoes & and additional 5 and 3/5 pounds of tomatoes to make soup.

4.8 + 5.6 = 10.5 pounds per soup

10.5*2 = 21 > 20 pounds

Farah would need one more pound of tomatoes in order to make 2 batches of soup. Therefore she can only make 1 batch.

Answer:

+4√5

Step-by-step explanation:

Note that this is a right triangle.  Therefore, the lengths of the three sides are related through the Pythagorean Theorem:  a^2 + b^2 = c^2, where c is the length of the hypotenuse.  

Thus, x^2 + 19^2 = 21^2, or, after solving this for x^2,

x^2 = 441 - 361 = 80

x is therefore +√80, or +4√5.

Answer:

Decrease

Step-by-step explanation:

50 is bigger than 20, so it's decreasing and the units are the same.

Answer:

The length is 9 feet and the width is 4 feet.

Step-by-step explanation:

Let the dimensions be L (the length)  and L - 5 (the width).

From the given information the area is:

A = L(L - 5)

When L becomes L + 3 and width becomes (L - 5) -1  = L - 6 we have:

A = (L + 3)(L - 6) so

L(L - 5) = (L + 3)(L - 6)

L^2 - 5L = L^2 - 3L - 18

-2L  = -18

L = 9

so the width = 9 - 5 = 4.

Answer:

5 feet high

Step-by-step explanation:

A= LxW

Yx4= 20

  /4    /4

Y= 5ft

It is 5ft high

1. Yes, angles a and b have a common vertex (starting point) and a common side (the line between angle a and b). They do not overlap.

2. No, angles a and b share a common vertex but not a common side.

3. No. Same as above.

4. Yes, anlges a and b share a common vertex and side.

Pregunta completa:

Una caja contiene lápices azules y rojos. ¿Cómo se interpreta que la relación entre

los lápices azul y rojo en la caja es 3: 1?

A Hay tres lápices rojos y un lápiz azul.

B Hay tres lápices azules y un lápiz rojo.

C Hay tres veces más lápices rojos que azules.

D Hay tres veces más lápices azules que rojos.

Responder:

B Hay tres lápices azules y un lápiz rojo.

Explicación paso a paso:

Si se le da eso; La relación entre los lápices azul y rojo es de 3: 1

El primer número en la expresión de razón representa el color del lápiz indicado primero en la expresión

Por lo tanto ;

Lápiz de color azul = 3

Lápiz de color rojo = 1

Por lo tanto, hay tres lápices azules y un lápiz rojo.

Answer:

[tex]12x+8y[/tex]

Step-by-step explanation:

1) Expand by distributing terms.

[tex]4*3x+4*2y[/tex]

2) Simplify 4*3x to 12x.

[tex]12x+4*2y[/tex]

3) Simplify  4*2y to 8y.

[tex]12x+8y[/tex]

Therefor, the answer is 12x + 8y.

Answer:

Perimeter of rectangle = 4x + 80

Area = x² + 40x + 384

Step-by-step explanation:

Perimeter of rectangle = 2*(length + width)

                                      = 2* (x + 24 + x + 16)

                                      = 2*( x +x + 24 + 16)    {Combine like terms}

                                      = 2* (2x + 40)

Use Distributive property : a*(b +c) = a *b + a*c

                                     = 2*2x + 2*40

                                     = 4x + 80

Area of rectangle = length * width

                             = (x + 24) (x + 16) {use FOIL method}

                            = x*x + x*16 + 24*x + 24*16

                             = x² + 16x + 24x + 384  {Combine like terms}

                             = x² + 40x + 384
