Well, yeah, sometimes we have that weird feeling that our guts know the answer but we don't know why. Let me show you how I got mine.
Gravitational force obeys an inverse square law - as in the gravitational force depends on the distance as<span>F = <span><span>GMm/</span><span>r</span></span></span>²
Small m is the mass of astronaut, M the planet, etc. equate the two forces to have the astronaut in equilibrium. G, m cancel, then arrange to get the Mass ratio:<span><span><span><span>Mx / </span><span>My</span></span> =<span><span>140</span></span></span></span>²/581²
Answer:
87 customers
Step-by-step explanation:
Consider the below table is attached with this question.
From the below table it is clear that the number of customers entered between 1:00 to 4:00 is
![30+14+18=62](https://tex.z-dn.net/?f=30%2B14%2B18%3D62)
The number of customers leaved between 1:00 to 4:00 is
![-12-8-30=-50](https://tex.z-dn.net/?f=-12-8-30%3D-50)
Total change in the number of customers between 1:00 to 4:00 is
![62-50=12](https://tex.z-dn.net/?f=62-50%3D12)
There were 75 customers in the store at 1:00. So, total number of customers at 4:00 is
![75+12=87](https://tex.z-dn.net/?f=75%2B12%3D87)
The store must be emptied of customers when it closes at 5:00
Therefore, 87 customers must leave the store between 4:00 and 5:00.
