horsena [70]

David purchased some cookies at the cost of

5 for $4 (5/4=1.25) and


sold them at 4 for $5(4/5=0.80).


To find cost per cookie subtract 1.25-0.80=0.45


David made a profit of $180 in total ( divide profit per cookie cost: 180/0.45= 400)


How many cookies did David purchase to make that much money?


He needed to make 400 cookie to make the profit of $180.

A 20-kilogram mass is attached to a spring. If the frequency of simple harmonic motion is 2/p cycles/s, what is the spring const
SVEN [57.7K]

Step-by-step explanation:

Frequency of a mass-spring system is:

f = √(k/m) / (2π)

Given f = 2/π Hz and m = 20 kg:

2/π Hz = √(k / 20 kg) / (2π)

4 Hz = √(k / 20 kg)

16 s⁻² = k / 20 kg

k = 320 kg/s²

k = 320 N/m

If the 20 kg mass is replaced with an 80 kg mass, the frequency is:

f = √(320 kg/s² / 80 kg) / (2π)

f = √(4 s⁻²) / (2π)

f = 2 Hz / (2π)

f = 1/π Hz
