Answer: \frac{7}{6}

Step-by-step explanation:

\frac{\frac{x}{4}+\frac{x}{3}  }{\frac{x}{2} }

Multiply by the reciprocal of the fraction of the denominator. Basically invert the fraction and multiply by the numerator.

(\frac{x}{4}+\frac{x}{3})(\frac{2}{x})

Solve the sum.

(\frac{x*3+x*4}{4*3})(\frac{2}{x})

(\frac{3x+4x}{12}) (\frac{2}{x})

\frac{6x+8x}{12x}=\frac{14x}{12x}

\frac{7}{6}

klasskru [66]

Answer:

(0,-5)

Step-by-step explanation:

3(4x+4y=20)

-3x-12y=-60

12x+12y=60

-3x-12y=-60

9x=0

x=0

4(0)+4y=-20

A plane flies at 350 mph in the direction N 40° E with a wind blowing at 40 mph in the direction S 70° E. What is the plane’s dr
kozerog [31]

Answer:

The drift angle is approximately 7.65° towards the East from the plane's heading

Step-by-step explanation:

The speed of the plane = 350 mph

The direction in which the plane flies N 40° E = 50° counterclockwise from the eastern direction

The speed of the wind = 40 mph

The direction of the wind = S 70° E = 20° clockwise from the eastern direction

The component velocities of the plane are;

R_{Plane} = (350 × cos 50)·i + (350 × sin 50)·j

R_{Wind} = (40 + cos 20)·i - (40 × sin 40)·j

The resultant speed of the plane = R_{Plane} + R_{Wind} = 265.915·i +242.404·j

The direction the plane is heading = tan⁻¹(242.404/265.915) ≈ 42.35°

Therefore, the drift angle = Actual Angle - Direction of the plane = 50 - 42.35 ≈ 7.65° towards the East

Barry made the model to show multiplying a fraction by a fraction. Which multiplication sentence does the model show? A grid wit
barxatty [35]

Given:

Number of rows = 3

Number of columns = 6

Number of square boxes = 18

yellow square boxes in the top two rows = 12

Blue square boxes in the first 5 columns = 15

Number of green boxes (shading overlaps) = 10

To find:

The model to show multiplying a fraction by a fraction.

Solution:

2 rows out of 3 are shaded yellow.

Fraction for yellow = \dfrac{2}{3}

5 columns out of 6 are shaded blue.

Faction for blue = \dfrac{5}{6}

10 out of 18 squares are green.

Faction for green =  \dfrac{10}{18}=\dfrac{5}{9}

Now,

\dfrac{2}{3}\times \dfrac{5}{6}=\dfrac{10}{18}

\dfrac{2}{3}\times \dfrac{5}{6}=\dfrac{5}{9}

Therefore, the correct option is D.
