First, find the difference between the original price and the reduced price;

65 - 45 = $20 difference

Then, divide the difference by the original amount;

20/65 ≈ 0.3077

Then, multiply this by 100 to convert the decimal into a percentage;

0.3077 * 100 = 30.77%

The percent of change would be about 30.77%

Laura can weed the garden in 1 hour and 20 minutes and her husband can weed it in 1 hour and 30 minutes. How long will they take
Harrizon [31]
<h2>Hello!</h2>

The answer is:

It will take 42.35 minutes to weed the garden together.

<h2>Why?</h2>

To solve the problem, we need to use the given information about the rate for both Laura and her husband. We know that she can weed the garden in 1 hour and 20 minutes (80 minutes) and her husband can weed it in 1 hour and 30 minutes (90 minutes), so we need to combine both's work and calculate how much time it will take to weed the garden together.

So, calculating we have:

Laura's rate:

\frac{1garden}{80minutes}

Husband's rate:

\frac{1garden}{90minutes}

Now, writing the equation we have:

Laura'sRate+Husband'sRate=CombinedRate

\frac{1}{80}+\frac{1}{90}=\frac{1}{time}

\frac{1*90+1*80}{7200}=\frac{1}{time}

\frac{170}{7200}=\frac{1}{time}

\frac{17}{720}=\frac{11}{time}

\frac{17}{720}=\frac{1}{time}

\frac{17}{720}*time=1

time=1*\frac{720}{17}=42.35

Hence, we have that it will take 42.35 minutes to weed the garden working together.

Have a nice day!

The population P of a small town, measured in hundreds, is modeled by the inverse of the function P−1(t) = 10ln(50t − 1000), whe
AleksandrR [38]

Using the inverse function, it is found that the equation is:

P(t) = \frac{e^{0.1t}}{50} + 20

It's initial value is 20.

---------------------------

We want to find the inverse of:

y = P^{-1}(t) = 10\ln{50t - 1000}

To do this, we <u>exchange y and t, and isolate y.</u>

Then:

10\ln{50y - 1000} = t

\ln{50y - 1000} = \frac{t}{10}

e^{\ln{50y - 1000}} = e^{0.1t}

50y - 1000 = e^{0.1t}

50y = e^{0.1t} + 1000

y = \frac{e^{0.1t} + 1000}{50}

y = \frac{e^{0.1t}}{50} + \frac{1000}{50}

P(t) = \frac{e^{0.1t}}{50} + 20

It's initial value is:

P(0) = \frac{e^{0.1(0)}}{50} + 20 = 0.02 + 20 = 20.02

Rounding, 20.
