After 4 hours of renting the bus both companies would charge 300 dollars.

Answer:

4 hours

Step-by-step explanation:

$100 (base price) + 200 (4 hrs at a $50 rate) = $300

$200 (base price) + $100 (4 hours at a $25 rate) = $300

Answer:

B

Step-by-step explanation:

Draw a line from the top of the 3 m line to the 10 m line so that the new line meets the the 10 meter line at right angles. The part you are interested in should be 4 meters long.

Top rectangle.

Area = L * W

L = 7  (10 - 3 = 7)

W = 4

Area = 4* 7 =                                       28

Bottom rectangle

Area = L * W

L = 12

W = 3

Area = 12 * 3                                      36

Total Area                                          64

Answer:

Step-by-step explanation:

Area of the shaded region is 223.72 square units.

Step-by-step explanation:

Area of the shaded region = Area of parallelogram - Area of triangle

Area of the parallelogram = base x height

= 23.8 x 15

= 357 square feet

Area of triangle = \frac{1}{2}

2

1

x base x height

Let the height of the triangle be represented by h, applying the Pythagoras theorem;

23.8^{2}23.8

2

= 21^{2}21

2

+ h^{2}h

2

566.44 = 441 + h^{2}h2

h^{2}h

2= 125.44

h = \sqrt{125.44}

125.44

= 11.2

h = 11.2

Area of the triangle = \frac{1}{2}

21 x 23.8 x 11.2 = 133.28

Area of shaded region = 357 - 133.28

= 223.72

Area of the shaded region is 223.72 square units.

Answer:

15x^2 - 14x - 8 = 0.

Step-by-step explanation:

(x  - 4/3)(x + 2/5) = 0

Converted to integer values by multiplying the first bracket by 3 and the second by 5:

(3x - 4)(5x + 2) = 0

Expanding the brackets:

15x^2 + 6x - 20x - 8 = 0

15x^2 - 14x - 8 = 0.

Answer:

2/5 = 40% 16/25 = 64% 9/25 = 36% 21/50 = 42%

Answer:

848 is the answer

The volume of the cone is approximately 282.74 cubic centimeters.

It is a shape of a Christmas tree where there is a base of radius r and a top point called the apex.

We have,

The formula for the volume of a cone is V = (1/3)πr²h,

where r is the radius of the base and h is the height of the cone.

Substituting the given values.V = (1/3)π(9 cm)²(10 cm)

V = (1/3)π(81 cm²)(10 cm)

V = (1/3)π(810 cm³)

V = (270/3)π cm³

V = 90π cm³

V ≈ 282.74 cm³ (rounded to the nearest tenth)

Therefore,

The volume of the cone is approximately 282.74 cubic centimeters.

Answer:

h = 1.65 m

Step-by-step explanation:

Me parece que el problema está mal formulado por lo siguiente:

El angulo al que se refiere el problema es 54°  o es 50°  o es 54°,50´

Como resolver el problema en cualquier caso.

Si Elisa y su sombra forman un angulo recto, entonces Elisa, su sombra y la distancia entre la cabeza de Eliza y el final de su sombra forman un triangulo rectangulo. Para el cual entonces solo es necesario buscar la tangente del angulo ( cateto opuesto sobre cateto adyacente) como conocemos el cateto adyacente ( la sombra de Elisa ) calculamos la altura de Elisa (h).

Asumamos que el angulo es de 54°  entonces

tang 54° = 1.3763

tang 54° = 1.3763  = h/1.2

h = 1,3763*1,2  m

h = 1.65 m

De igual manera se procedería si el angulo es de 50° ( en este caso la    tang 50° = 1.1917

Step-by-step explanation:

a + c = 5

9a + 4c = 30

let a = 5-c

substitute:

9(5-c) + 4c = 30

45 - 9c + 4c = 30

45 - 5c = 30

-5c = -15

c = 3

Answer:

2.6

Step-by-step explanation:

Given :

x 1 2 3 4

P(x) 0.3 0.2 ? 0.4

Σp(x) = 1

Hence, 0.3 + 0.2 +? + 0.4 = 1

0.9 +? = 1

? = 1 - 0.9

? = 0.1

For the mean :

E(X) = ΣX*P(X)

(1 * 0.3) + (2 * 0.2) + (3 *0.1) + (4* 0.4)

0.3 + 0.4 + 0.3 + 1.6 = 2.6

Hence, the mean = 2.6
