That the answer ur welcome
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:
Required value of k is 43% .
Explanation:
Lets assume original regular price of sports jacket = x
On sale , price of jacket is reuced by 30%
Sales price = x - 30% 0f x
Sales price= x – 0.30x
Sales price= 0.70x
Once sales is over price of jacket is increased by k%
That is
Sales price + k% of Sales price
= 0.70x + k% 0.70x
Also given after increasing to k% , price becomes equal to regular price
=> 0.70x + k% of 0.70x = original regular price
=>
=>
=>
=> 0.70k = 100 x 0.30
=>that is 43
Hence required value of k is 43% .
The ANWSER is 16 I don't think I can show you a area model try your best you can make 64 squares the get and put them into groups of 4 if that helps and there should be 16 groups
