Answer:

about 1.4 hours

Step-by-step explanation:

3.13 gallons per minute.

60 minutes in an hour, so multiply both numbers by 60.

187.8 gallons per hour.

Divide the number of gallons we need to fill the tub the number of gallons put in per hour.

255÷187.8=1.375...

Round it, you get 1.4 hours.

It takes about 1.4 hours to fill the hot tub.

7. When dy/dx = (x -6)1/2, what does y equal?
Sergio039 [100]
The answer is below
\frac{dy}{dx} = \frac{1}{2} (x - 6)
multiply both sides by dx

dy = \frac{1}{2} (x - 6)dx
integrate both sides of the diffrential

integral \: dy = integral \: \frac{1}{2} (x - 6)dx
simplify and integrate to get y alone don't forget to tack on c with your indefinite integral

y = \frac{x {}^{2} }{4} - 3x + c

How do you do inverse operation on a fraction ( y/3 ) = -6
NemiM [27]

\frac{-1}{18}

Solution:

Given expression is \frac{y}{3}=-6

To find the inverse of y.

⇒ \frac{y}{3}=-6

Do cross multiplication.

⇒ y = –6 × 3

⇒ y = –18

Inverse of y means reverse the function.

We know that inverse of y is \frac{1}{y}.

⇒ \frac{1}{y}= \frac{-1}{18}

Hence, inverse of y is \frac{-1}{18}.
