There are 60 minutes in an hour, 3 hours to fill up, therefore the problem should be 180/3.5.
They need about 52 songs.
Hope this helped!

An hour is 60 minutes

there are three hours so 
60*3=180

how many times will 3.5 go into 180 so 
180/3.5=51.43 or rounded up you get 52 songs (if they're good, they'll play 52 average songs and one half legnth songs)
so they will need 52 songs

Fill in the blank so that 81x2+_<br> x+81 is a perfect square trinomial.<br> 81x²+_____<br><br> x+81
densk [106]

the blank is 162

since 81 and 81 are both perfect squares the middle term (blank) will be the product of their roots times 2

√81=9

√81 =9

9 x 9 x 2

= 162

Fill in the blank by performing the indicated elementary row operation(s).
Scilla [17]

In this question, we are given a matrix, and we have to perform the given operation.

The matrix is:

\left[\begin{array}{ccc}6&-1&|5\\1&-5&|0\end{array}\right]

The following operation is given:

R_1 \rightarrow -6R_2 + R_1

In which R_1 is the element at the first line and R_2 is the element at the second line.

Updating the first line:

R_{1,1} = -6*1 + 6 = 0

R_{1,2} = -6*-5 - 1 = 30 - 1 = 29

R_{1,3} = -6*0 + 5 = 5

Thus, the filled matrix will be given by:

\left[\begin{array}{ccc}0&29&|5\\1&-5&|0\end{array}\right]
