The answer is 5/3, but I don’t know the solution.
VLD [36.1K]

Check the picture below.

let's bear in mind that the segment MN is simply the sum of MQ + QN, and since M and N are midpoints, they cut that respective section into two equal halves.

\bf \begin{cases} PQ=5QR\\ MN = \frac{PQ}{2}+\frac{QR}{2} \end{cases}\qquad \qquad \cfrac{PQ}{MN}\implies \cfrac{5QR}{\frac{PQ}{2}+\frac{QR}{2}}\implies \cfrac{5QR}{\frac{PQ+QR}{2}} \\\\\\ \cfrac{\frac{5QR}{1}}{\frac{PQ+QR}{2}}\implies \cfrac{5QR}{1}\cdot \cfrac{2}{PQ+QR}\implies \cfrac{10QR}{\underline{PQ}+QR}\implies \cfrac{10QR}{\underline{5QR}+QR}

\bf \cfrac{~~\begin{matrix} 10QR \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}{~~\begin{matrix} 6QR \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}\implies \cfrac{5}{3}

I need the help alot​
GuDViN [60]

Answer:

{-5/4, 8}

Step-by-step explanation:

We are given (4u + 5)(8 - u) = 0.  Solve for u by setting each of the factors (4u + 5) and (8 - u) equal to zero and solving each of the resulting equations:

4u + 5 = 0 leads to u = -5/4, and

8 - u = 0 leads to u = 8.

The solutions are {-5/4, 8}

Someone you know is planning a wedding. They have still have decide on the place of the reception, the DJ, and the caterer. They
Aliun [14]
So essentially, we have a choice of :

2 reception halls
3 DJs
2 catering companies.

In order to find the number of arrangements, you need to multiply those : 2*3*2=12- So they have 12 arrangements.

why?

Imagine those 3 Djs- they are three arrangements.
Now, they can play in one or the other hall -so in total it's 3 Djs in one hall and 3 in the other -that's 6.

And all of those 6 possibilities can be catered by one or the other company- making the possibilities twice as many, so it's 12 in total!
