Answer:

Se necesita 36 bolsas con 2 cuadernos, 5 marcadores y 4 lapiceras por unidad.

Step-by-step explanation:

Los cuadernos corresponden a los artículos con menor inventario. Las razones de marcadores y lapiceras por cuaderno son, respectivamente:

Marcadores

[tex]x = \frac{180\,marcadores}{72\,cuadernos}[/tex]

[tex]x = \frac{5\,marcadores}{2\,cuadernos}[/tex]

Cada bolsa debe contener 5 marcadores por cada 2 cuadernos.

Lapiceras

[tex]y = \frac{144\,lapiceras}{72\,cuadernos}[/tex]

[tex]y = \frac{2\,lapiceras}{1\,cuaderno}[/tex]

Cada bolsa debe contener 2 lapiceras por cada cuaderno.

El número máximo de bolsas es:

[tex]z = \frac{72\,cuadernos}{2\,\frac{cuadernos}{bolsa} }[/tex]

[tex]z = 36\,bolsas[/tex]

Se necesita 36 bolsas con 2 cuadernos, 5 marcadores y 4 lapiceras por unidad.

Answer:

50/120 =12:5

Step-by-step explanation:

First we are divide 50/120

answer is 12:5

Answer: 0.05 : 120. OR

50 : 120000 or 1:2400

Step-by-step explanation:

Speed of garden snail

= 50 meters per hour = 0.05 kph

Speed of cheetah

= 120 km per hour or 120000 mph

Ratio of snail : cheetah

= 0 05 : 120

x=-4 if you are in a hurry

The solution of the equation are; x = -16 or x = -4. so option A is correct.

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

Given equation;

x²+ 20 x + 100 = 36.

x²+ 20 x + 100 - 36 = 0

x²+ 20 x + 64 = 0.

x²+ (16 + 4)x + 64 = 0.

x²+ 16x + 4x + 64 = 0.

x(x + 16) +4 (x + 16) = 0.

(x+ 4) (x + 16) = 0

Thus, the solution of the equation are; x = -16 or x = -4.

Step-by-step explanation:

The solution of the equation 2 (4 – 3x) + 5 (2x – 3) = 20 – 5x will be 3. Then the correct option is D.

The solution of the equation means the value of the unknown or variable.

The equation is given below.

2 (4 – 3x) + 5 (2x – 3) = 20 – 5x

Simplify the equation, we have

2 (4 – 3x) + 5 (2x – 3) = 20 – 5x

      8 – 6x + 10x – 15 = 20 – 5x

                              9x = 27

                                x = 3

Then the correct option is D.

Answer:

If angle 2 = 110 then angle 4 = 110

360 = 110 + 110 + x

Angle 1 + Angle 3 = 140

Since vertical angles are equal, then Angle 1 = 140 / 2 = 70 degrees

Step-by-step explanation:

Step-by-step explanation:

∠3+∠4= 180°

Since ∠2 ≅ ∠ 4 and  ∠2= 110°

∠3= 180° - ∠4= 180° - ∠2= 180° - 110°= 70°

Answer:

m = 57/14 = [tex]4\frac{1}{14}[/tex]

Step-by-step explanation:

The polynomial can be expressed as follows;

P(x) = 2·x³ - m·x² + x - 5·m

(2·x³ - m·x² + x - 5·m) ÷ (x - 2)

          2·x²

          (-m - 2)·x² + x

                   (-m - 2)·x

                      (m + 3)·x - 5·m

                      (m + 3)·x

                                      -5·m

The remainder = -5·m/(x -2)

Similarly, dividing by (x + 1) will give a remainder of -5·m/(x + 1)

But -5·m/(x -2) = 4×-5·m/(x + 1)

5/(x -2) = 20/(x + 1)

5(x + 1) = 20(x -2)

20x - 5x= 40 + 5

x = 45/15 = 3

2·3³ - m·3² + 3 - 5·m = 54 - 9m + 3 - 5m = 57 - 14m

(57 - 14m)/1 = (57 - 14m)/4

228 - 56m =57 - 14m

171 = 56m-14m =  42m

m = 171/42 = 57/14.

Answer:

1) ∠AEB ≈ 83.7°

2) CE  = 6.1 cm

3) BC ≈ 7.1 cm

Step-by-step explanation:

1) Use theorem of cosine

c² = a² + b² - 2ab*cos(α)

4.5² = 3² + 3.7² - 2*3*3.7 *cos(∠AEB)

cos(∠AEB) = (4.5² - 3² - 3.7²) /(- 2*3*3.7) = 0.11

∠AEB = arc cos(∠AEB) = arc cos(0.11) ≈ 83.7°

2)

∠CED =∠AEB = 83.7° as vertical angles

Use law of sine

CD/sin(∠CED) = CE/ sin(∠CDE)

7/sin(83.7) = CE/sin(60°)

CE = 7*sin(60°)/sin(83.7°) = 6.1 cm

3.

∠BEC + ∠CED = 180°

∠BEC = 180° - ∠CED = 180° - 83.7° = 96.3°

Use theorem of cosine

c² = a² + b² - 2ab*cos(α)

BC² = BE² + CE² - 2 BE * EC *cos(∠BEC)

BC² = 3² + 6.1² - 2*3 * 6.1 *cos(96.3°) ≈ 50.23 cm

BC = √(50.23)≈ 7.1 cm

Amount in account after one year, two and three years are respectively  $2,060 , $2,121.8 and $2,185.45

Given:

Principal amount = $2,000

Rate of interest = 3% = 0.03

Amount in account after one year

A = P(1+r)ⁿ

A = 2,000(1+0.03)¹

A = 2,000(1.03)¹

A = 2,000(1.03)

A = $2,060

Amount in account after two year

A = P(1+r)ⁿ

A = 2,000(1+0.03)²

A = 2,000(1.03)²

A = 2,000(1.0609)

A = $2,121.8

Amount in account after three year

A = P(1+r)ⁿ

A = 2,000(1+0.03)³

Answer:

1715 metros

Step-by-step explanation:

Lo que debemos hacer es calcular la distancia del primer y del segundo eco.

Debemos conocer la velocidad del sonido que en términos generales es 343 m/s, por lo tanto, la distancia sería igual a:

v = d/t => d = v*t

d1 = 343*2 = 686 metros

d2 = 343*3 = 1029 metros

La separación sería la suma de ambas distancias así:

686 + 1029 = 1715

1715 metros sería la distancia de separación entre ambas montañas.

Step-by-step explanation:

2/3y + 15 = 9

Subtract 15 from each side

2/3y + 15-15 = 9-15

2/3y = -6

Multiply each side by 3/2 to isolate y

3/2 * 2/3y = -6 *3/2

y = -9

Answer:

y = - 9

Step-by-step explanation:

2/3y + 15 = 9

Subtract 15 on both sides.

2/3y = 9 - 15

2/3y = - 6

Multiply both sides by 3/2.

y = - 6 × 3/2

y = -18/2

y = -9
