Maddie swims the hundred meter freestyle in 30 seconds what is her average speed in meters per minute

1 answer:

3 0

Answer: 200 meters per minute

Explanation: we know that she can run 100 meters per 30 seconds. the question is asking in terms of minutes, however. we have to convert the seconds into minutes. How many minutes is 30 seconds? well, 60 seconds are in a minute so 30 seconds are in half a minute. 30 seconds = .5 minutes.

Now, we have to find how many meters she runs per minute. this means how many meters she runs in one minute. we create a proportion:

100 meters/ .5 minutes = x meters / 1 minute

we cross multiply to get 100 = .5x

then, we simplify by dividing each side by .5 which equals

200=x

The answer is true.

Method 1:
The given function is a cubic function. And inverse of a cubic function is also a function.

Method 2:
Since the function is one-to-one function i.e it passes the horizontal line test, its function will pass the vertical line test which is a test if a relation is a function or not.

So, yes the inverse of G(x) will be a function.

Solve= 10/8 = n/10 <br> Write your answer as an improper fraction in simplest form.

<h2>Answer:</h2>

$n=\frac{25}{2}$ .

<h2>Step-by-step explanation:</h2>

<h3>1. Write the expression.</h3>

$\frac{10}{8} =\frac{n}{10}$

<h3>2. Solve the equation for n.</h3>

$\frac{10}{8} =\frac{n}{10}$

$10*(\frac{10}{8}) =(\frac{n}{10})*10$ ----> Multiply both sides by 10.

$10*(\frac{10}{8}) =n$ ----> Simplify.

$\frac{10*10}{8} =n$ ----> Solve the fraction product.

$\frac{100}{8} =n$ ----> Simplify.

$\frac{100/4}{8/4} =n$ ----> Simplify by dividing the numerator and denominator by the same number.

$\frac{25}{2} =n$ ----> Simplify.

$n=\frac{25}{2}$ ----> Reorganize.

<h3>3. Express your result.</h3>

$n=\frac{25}{2}$ .

<em>Note. </em><em>Check the attched image to see the manual solution of the equation. We took the same steps I explained previously in the manual solution.</em>
