It takes 20.833 minutes to fill a 50 gallon tub
<em><u>Solution:</u></em>
Given that,
It takes 1 & 1/4 minutes to fill a 3-gallon bucket of water with a hose

Let "x" be the time taken to fill a 50 gallon tub
Therefore, from given,
1.25 minutes = 3 gallon
x minutes = 50 gallon
This forms a proportion and we can solve the sum by cross multiplying

Thus it takes 20.833 minutes to fill a 50 gallon tub
Step-by-step explanation:
Let P be price after t year . From the formula of compounding
P = 9 (1.015)^t
Taking log to the base e on both sides
ln P = ln 9 + t ln 1.015
= (2.197 + .0149t )
P = e^{(2.197+.0149t)}
1. distributivity of the multiplication (a+b)(c-d)=a(c-d)+b(c-d)
2. the same
3. comutativity of the multiplication a*b=b*a
4. we give common factor xy: -5xy+2xy=xy(-5+2)=-3xy
11.x + 21 < 131
11.x < 131 - 21
11.x < 111
x<1
Answer: 7 + 2/3(12) = 15
