Encuentra la velocidad promedio de un móvil que durante su recorrido hacia el Norte tuvo las siguientes velocidades.

yan [13]

The mean or average speed of a mobile moving north is: <u>Vprom= 20.575 m/sec</u>

The average speed of a series of given speed values is calculated by <u>summing</u> each of the <u>speeds</u> and then <u>dividing</u> by the number of speeds , as follows:

Speeds:

V1=18.5m/s

V2=22m/s

V3=20.3m/s

V4=21.5m/s

V avg =?

Average V = ( V1+V2+V3 +V4)/4

Vavg = (18.5m/s + 22m/s +20.3m/s + 21.5m/s)/4

Vavg = 20.575nm/sec

Evan is on holidays in Beijing, China. He took a taxi from the airport to his hotel. It cost him 375 Chinese yuan. He went $15 A

Alekssandra [29.7K]

This question is solved using proportions, and doing this, it is found that Evan gets 5 Chinese yuans for every Australian dollar.

-----------------------------------------

Evan budgeted $60 for the taxi ride.
He went $15 over, thus, the taxi ride cost $75.
In Chinese yuans, the cost was 375.

-----------------------------------------

75 dollars are worth 375 yuans. How much yuans is a dollar worth?

1 dollar - x yuans

75 dollars - 375 yuans

Applying cross multiplication:

$75x = 375$

$x = \frac{375}{75}$

$x = 5$

Evan gets 5 Chinese yuans for every Australian dollar.

A toy company is considering a cube or sphere-shaped container for packaging a new product. The height of the cube would equal t

Darya [45]

Answer:

Packaging with cube will be more efficient.

Step-by-step explanation:

Given:

A cube and a sphere where the diameter of the sphere is equal to the height of the cube.

Let the height of the cube "x"

Radius of the sphere = $(\frac{x}{2})$

Formula to be used:

Surface area of the cube = $6x^2$ and Surface area of the sphere = $4\pi (r)^2$

Volume of the cube = $x^3$ and Volume of the sphere = $\frac{4\pi r^3}{3}$

We have to compare the ratio of SA and Volumes.

Ratio of SA : Ratio of their volumes :

⇒ $\frac{SA\ of\ cube\ (S_1)}{SA\ of\ sphere\ (S_2)}$ ⇒ $\frac{Volume \ of \ cube\ (V_1)}{Volume\ of\ sphere\ (V_2)}$

⇒ $\frac{6x^2}{4\pi (\frac{x}{2})^2}$ ⇒ $\frac{x^3}{\frac{4 \pi r^3}{3} }$

⇒ $\frac{6x^2}{4\pi (\frac{x^2}{4})}$ ⇒ $\frac{x^3}{\frac{4 \pi (\frac{x}{2})^3}{3} }$

⇒ $\frac{6x^2}{\pi x^2}$ ⇒ $\frac{x^3}{\frac{4 \pi (\frac{x^3}{8})}{3} }$

⇒ $\frac{6}{\pi}$ ⇒ $\frac{6}{\pi}$

⇒ approx $2$ ⇒ approx $2$

⇒ $S_1=2S_2$ ⇒ $V_1=2V_2$

Packaging of the toy with the cube will be more efficient as it has more volume comparatively.
