It's 3 different types of music and he can only pick 12 songs. So 3÷12=4 . Therefore he can pick 4 songs from each category.
Pressure and Volume are inversely related as:
![P= \frac{R}{V}](https://tex.z-dn.net/?f=P%3D%20%5Cfrac%7BR%7D%7BV%7D%20)
We can also write it as:
![PV=R](https://tex.z-dn.net/?f=PV%3DR)
R is the constant of proportionality. Using the first row of given table, we can write:
Thus, the value of R, the universal gas constant is 8.31
The answer is 3167.
First, multiply the numbers by their place values:
3 x 1000 = 3000
16 x 10 = 160
7 x 1 = 7
Then, add together the sums: 3000 + 160 + 7 = 3167
Let t = the total number of hamburgers and cheeseburgers, c = the total number of cheeseburgers, and h = the total number of hamburgers.
t = c + h where t = 600
c = h + 50
Use substitution to solve for h:
600=(h+50)+h
600= 2h+50
600-50=2h
550=2h
550/2=2h/2
h=275
therefore, 275 hamburgers were sold on thursday.
