Answer:
Since the value is always multiplied by the same factor(19), the relationship is proportional.
Step-by-step explanation:
To see if the equation represents a proportional relationship, we see if the division of y by x is always the same
So
Equal, so proportional
The formula of a volume of a rectangle prism:

We have

Answer:
0.625
Step-by-step explanation:
0.625 * 8 = 5
Since the songs are $1 each and the audio books are $4 so for every ONE audio book he buys at $4, he will buy THREE songs at $1 each. So if he buys 5 audio books he will buy 15 songs and in turn spend $20 on audio books and $15 on songs. You can make a formula to solve this problem if S= amount of songs and A= amount of audio books
S=A*3 input the number of Audio books and you get the number of songs per audio book. For example S=5*3 S=15 so you have 15 songs when you buy 5 audio books.
In order to calculate price (Total price = T), T=S+(A*4) This can only be calculated once you do the first formula. So since A=5 and S=15
T=15+(5*4) T=$35 If Ben buys 5 Audio Books and 15 songs, he will spend $35
Using the formula, Ben can buy 6 Audio books and 16 songs and spend $40
So Ben's options are either spending $35 and having 3 times as many songs as he does Audio books
Or spending all of his $40 and buying 1 more of each
(Additionally, he could buy 5 more songs and spend the same amount of money)
There are 16 ounces in 1 pound and 8 ounces in 0.5 pounds. 16(2)= 42+ 8= 38 ounces
