Depende on situation but no not always the same as y and x
Answer:
20 minutes; 240 barrels
Step-by-step explanation:
Old line = 40 + 10t
New line = 12t
Equal when,
40 + 10t = 12t
40 = 2t
t = 20 minutes
Each line will have:
12t = 12(20) = 240 barrels

Answer:
b. (4,14)
Step-by-step explanation:
Juan earns $7 per hour at his job.
This means that the ordered pairs showing his earnings y in x hours, (x,y), have the following format:
(x,7x).
Then, the ordered pairs are:
(1,7)
(2,14)
(3,21)
(4,28)
...
Thus, the ordered pair (4,14) would not appear on the graphic.
Answer:
sin θ = 15/17
Step-by-step explanation:
First we have to know how much the hypotenuse measures.
to take out the hypotenuse we will use pitagoras, with the following formula.
h^2 = c1^2 + c2^2
c1 = 8
c2 = 15
h^2 = 8^2 + 15^2
h^2 = 64 + 225
h = √ 289
h = 17
well to start we have to know the relationships between angles, legs and the hypotenuse.
a: adjacent
o: opposite
h: hypotenuse
sin θ = o/h
cos θ= a/h
tan θ = o/a
we want to know the sin of θ
sin θ = o/h
sin θ = 15/17
