serg [7]

Answer:

If Miles sells 6 tickets the money he will collect be <u>$36</u>.

Step-by-step explanation:

Given:

Miles sells 3 raffle tickets for $18 and 4 tickets for $24.

The pattern for the price of the tickets is the same.

Now, to find the money miles will collect if he sells 6 tickets.

Let the money Miles will collect be x.

The ticket if sells will be 6.

As, Miles sells 3 tickets for $18.

And the pattern for the price is same.

<em>So, 3 is equivalent to 18.</em>

<em>And, 6 is equivalent to </em>x.<em />

Now, to get the money by using cross multiplication method:

\frac{3}{18} =\frac{6}{x}

<em>By cross multiplying we get"</em>

<em />3x=108<em />

<em>Dividing both sides by 3 we get:</em>

x=36.

<u><em>The money MIles will collect = $36.</em></u>

Therefore,  if Miles sells 6 tickets the money he will collect is $36.

Simplify.<br> -sqrt m^4n^7
Delvig [45]

Answer:

-m^2 |n|^3 sqrt(n)

Step-by-step explanation:

-sqrt( m^4n^7)

We know that sqrt(ab) = sqrt(a) sqrt(b)

-sqrt(m^4) sqrt(n^7)

The sqrt(m^4) = m^2

The sqrt(n^7) = sqrt(n^6) sqrt(n) = |n|^3 sqrt(n)  We take the absolute value because if n is negative, n^6 is postive, but n^3 is negative

-sqrt(m^4) sqrt(n^7)

-m^2 |n|^3 sqrt(n)
