Un paracaidista que pesa 70 N es lanzado de un avión. halla su masa

77julia77 [94]

Answer:

<em>La masa del paracaidista es 7.14 Kg</em>

Step-by-step explanation:

La masa de un objeto es una medida de la cantidad de material que el objeto posee. Sus unidades más comunes son el Kg, gr, lb, Ton.

El peso de un objeto de masa m es la fuerza con la cual la Tierra atrae al objeto a través de la aceleración de gravedad g. Sus unidades son iguales a las de cualquier fuerza, es decir, Nw, Kgf, Dina. Su fórmula es:

P=m.g

Si tenemos el peso P=70 N, podemos calcular la masa, despejándola de la fórmula:

$\displaystyle m=\frac{P}{g}$

Sustituyendo los valores:

$\displaystyle m=\frac{70}{9.8}=7.14\ Kg$

La masa del paracaidista es 7.14 Kg

What is the area of a sector with a central angle of 2π/9 radians and a radius of 16.7 ft?

Y_Kistochka [10]

Answer:

Area of the sector is 97.30 square feet.

Step-by-step explanation:

The area of the sector is given by

$A=(\frac{\theta}{2})r^2$

Plugging the known values in this formula to find the area of the sector

$A=(\frac{2\pi/9}{2})(16.7)^2\\\\A=\frac{2\pi}{18}\cdot16.7^2$

Use the value of π as 3.14

$A=\frac{2\cdot3.14}{18}\cdot16.7^2$

Simplifying, we get

$A=97.3016$

Rounded to the nearest hundredth, we get

$A=97.30$

swat32

Answer:

length = 36 ft; width = 12 ft

Step-by-step explanation:

Let the width be x.

The length is 3x.

The perimeter is the sum of two lengths and two widths, and it equals 96 ft.

3x + 3x + x + x = 96

8x = 96

x = 12

Width = x = 12 ft

Length = 3x = 3(12 ft) = 36 ft
