Answer:

the plane flies 396,000yd in 30 min

Step-by-step explanation:

450 / 2 = 225

1 mile = 1,760

225 * 1,760 = 396,000 yd

Plz mark as brainliest if this helped! Have a nice day!!!

-Lil_G

Step-by-step explanation:

450 miles = 1hour = 60mins

X miles = 30mins

cross multiply

450 × 30 = 60 × X

13500 = 60X

divide through by 60

225 = X

therefore, X = 225miles

now

1 mile= 1760 yards

225 miles = X

cross multiply

X = 1760 ×225

X = 396000 yards

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

One rectangular prism has a length of 1 foot, width of 3 feet and height of 4 feet.

And, The second rectangular prism has a length as 6 feet, width as 3 feet and height as 2 feet.

Hence, Volume of first rectangular prism is,

⇒ 1 × 3 × 4

And,  Volume of second rectangular prism is,

⇒ 6 × 3 × 2

Thus, All the correct expressions that could be used to find the volume of the hamster house are,

⇒ (1 × 3 × 4) + (6 × 3 × 2)

Step-by-step explanation:

I just used this trick I remembered from Honors Geometry. I am now in Honors Algebra II w/ Trig. So this trick is what is used for 30-60-90 special right triangles

Answer:

the slope would be 2x

Step-by-step explanation:

Whenever you're given an equation y=mx+b, "mx" is what represents the slope whilst "b" represents the y-intercept  

The denominator of the first term is a difference of squares, such that

4a ² - b ² = (2a)² - b ² = (2a - b) (2a + b)

So you can write the fractions as

(4a ² + b ²)/((2a - b) (2a + b)) - (2a - b)/(2a + b)

Multiply through the second fraction by 2a - b to get a common denominator:

(4a ² + b ²)/((2a - b) (2a + b)) - (2a - b)²/((2a + b) (2a - b))

((4a ² + b ²) - (2a - b)²) / ((2a - b) (2a + b))

Expand the numerator:

(4a ² + b ²) - (2a - b)²

(4a ² + b ²) - (4a ² - 4ab + b ²)

4ab

So the original expression reduces to

4ab / ((2a - b) (2a + b))

or

4ab / (4a ² - b ²)

upon condensing the denominator again.

Answer:

∠7 = 85°

Step-by-step explanation:

∠1 = 180 - 115 = 65°              Because they are supplementary angles

∠2 = 180 - 65 - 85 = 30°      Because the sum of all interior angles in a triangle

                                             equals 180°

∠3 = 90°                               given

∠6 = 180 - 90 - 30 = 60°      Because they are supplementary angles

∠4 = 180 - 155 = 25°             Because they are supplementary angles

∠5 = 180 - 25 - 60 = 95°      Because the sum of all interior angles in a

                                             triangle equals 180°

∠7 = 180 - 95 = 85°              Because they are supplementary angles

Answer:

213.042  km

Step-by-step explanation:

We need to convert 213 km 42 m to km.

We know that,

1 km = 1000 m

or

1 m = (1/1000)km

So,

42 m = (42/1000) km

It means,

[tex]213\ km\ 42\ m=213\ km+\dfrac{42}{1000}\ km\\\\=213.042\ km[/tex]

So, the required answer is 213.042  km.

Answer:

  91 rad/s

Step-by-step explanation:

The relationship between angular velocity (ω) and constant angular acceleration (ω') is ...

  ω(t) = ω0 + t·ω'

  ω(0.25) = 95 = ω0 + 0.25(16)

  95 -4 = ω0 = 91 . . . rad/s

The initial angular speed was 91 radians per second.

Answer:

La persona está a 5 kilómetros con respecto al punto de partida.

Step-by-step explanation:

Considérese que la dirección norte coincide con el semieje +y y que la dirección este coincide con el semieje +x. A continuación, obtenemos las formas vectoriales equivalentes de cada afirmación:

(i) Una persona camina 7 kilómetros hacia el norte:

[tex]\vec r_{1} = 7\,\hat{j}\,[km][/tex]

(ii) Después 3 kilómetros hacia el este:

[tex]\vec r_{2} = 3\,\hat{i}\,[km][/tex]

(iii) Y luego, 3 kilómetros hacia el sur:

[tex]\vec r_{3} = -3\,\hat{j}\,[km][/tex]

El vector resultante de desplazamiento se construye a partir de la siguiente suma de vectores:

[tex]\vec R = \vec r_{1}+\vec r_{2} + \vec r_{3}[/tex] (1)

[tex]\vec R = 3\,\hat{i} + 4\,\hat{j}\,[km][/tex]

Asumiendo que la distancia coincide con el desplazamiento resultante, calculamos la distancia con respecto al punto de partida mediante el Teorema de Pitágoras:

[tex]\|\vec R\| = \sqrt{3^{2}+4^{2}}[/tex]

[tex]\|\vec R\| = 5\,km[/tex]

La persona está a 5 kilómetros con respecto al punto de partida.
