If $560 is sheared in the ratio 2:3:9 , the difference between the largest and the smallest shares is

Lesechka [4]

Answer:

The difference between the largest and the smallest shares is $280

Step-by-step explanation:

Total amount to be shared = $560

Ratios of share are 2:3:9 => Total of 14 equal portions

To get one portion, $560 / 14 = $40

First share is 2, therefore $40 x 2 = $80 (smallest share)

Second share is 3, therefore $40 x 3 = $120

Third share is 9, therefore $40 x 9 = $360 (largest share)

<u>TOTAL = $560</u>

The difference between the largest and the smallest = $360 - $80

= $280

A brick of mass 4 kg hangs from the end of a spring. When the brick is at rest, the spring is stretched by 3 cm. The spring is t

Zielflug [23.3K]

Answer:

Step-by-step explanation:

In this system we have the force of the spring and the gravitational force. The equation that describes that is

$F_{s}+F{g}=ma\\k(y_0+y)-mg=ma$

where y0 is the equilibrium position when the string is free and y0+y is the new equilibrium position when the object is hanged of the string. By replacing by derivatives we have

$ky_0+ky-mg=ma\\mg+ky-mg=ky=ma\\\\ky=m\frac{d^2y}{dt^2}\\\\my''+ky=0$

the solution for this differential equation is (by using the characterisic polynomial)

$y(x)=Acos(kt)+Bsin(kt)\\k=\omega^2m$

hope this helps!!
