Convert: 1 foot = 12 inches.
The volume of the cylindrical pool is: \(4,5\cdot\left(12\cdot12\cdot\pi\right)=4,5\cdot144\pi=648\pi\approx2035,75\left(ft^3\right)=24429\left(in^3\right)\)
So the cost for Maxwell to fill his pool is: \(\left(24429:231\right)\cdot0,15\approx15,86\approx16\left(cents\right)\)

OwO, it's a typo: it's suppossed to be width, okay?

If you use the AMGM theorem, you'll know that any rectangle achieves the maximum possible area when both of their measurements are equal, making it a square (a square is technically a rectangle too)
So we have p=q
Therefore, the equation will be q2+q=13+q2
<=>q=13(cm)
<=>p=q=13(cm)
<=>S=pq=132=169(cm2)
(P.S: don't do this here, cuz you'll get to a dead end, oof)
\(pq+q=13+q^2\)
\(\Leftrightarrow S=q^2-q+13\)

Hồ Thu Giang 19/03/2017 at 09:42If x = 3
=> \(\dfrac{a-3}{3}=\dfrac{3b-5}{5}\)
=> \(5\left(a-3\right)=3\left(3b-5\right)\)
=> 5a - 15 = 9b - 15
=> 5a = 9b
=> \(\dfrac{a}{b}=\dfrac{9}{5}\)
=> \(\dfrac{b}{a}=\dfrac{5}{9}\)
=> \(\dfrac{a}{b}-\dfrac{b}{a}=\dfrac{9}{5}-\dfrac{5}{9}=\dfrac{56}{45}\)

FA KAKALOTS 03/02/2018 at 12:40If x = 3
=> a−33=3b−55
=> 5(a−3)=3(3b−5)
=> 5a - 15 = 9b - 15
=> 5a = 9b
=> ab=95
=> ba=59
=> ab−ba=95−59=5645
