It would be 6.70 if you round it to the nearest tenth
You can find out which is the better deal by dividing the price by the amount of ounces available. Here are the unit prices for each answer choice: A (.15), B(.16), C(.12), and D(.15). The cheapest unit price would be the best deal. Thus, the answer is choice C! Hope this helped :))
Answer:
K = 3
a = 6
Step-by-step explanation:
F is directly proportional to a
That’s F = Ka
K is the constant
Divide both sides by a to get the constant k
K = F/a
When F = 24 and a =8
K = 24/8
= 3
When F = 18
a = ?
F = Ka
18 = 3 x a
18 = 3 x a
Divide both sides by 3
18/3 = 3 x a /3
6 = a
a = 6
It is to be noted that x = 7 while y = 4 (This is assuming that each unit on the graph is 1). The question is solved using knowledge of coordinates. Hence the coordinates of AB are (0,0) and (7, 4), where A is the origin.
<h3>What are coordinates?</h3>
Each of a series of numbers used to describe the position of a point, line, or plane is referred to as a coordinates in math.
Hence it is correct to state that the coordinates of line AB are: (0,0) ; (7,4), where A is the origin.

Answer:
Part 1) ![180\ hours](https://tex.z-dn.net/?f=180%5C%20hours)
Part 2) There are about ![298\ catfish](https://tex.z-dn.net/?f=298%5C%20catfish)
Step-by-step explanation:
Part 1) we know that
1 month=4 weeks
Let
x------> the number of hours of practice for three months
so
Convert months to weeks
3 months=3(4)=12 weeks
using proportion
![\frac{45}{3}\frac{hours}{weeks} =\frac{x}{12}\frac{hours}{weeks}\\ \\ x=45*12/3\\ \\x=180\ hours](https://tex.z-dn.net/?f=%5Cfrac%7B45%7D%7B3%7D%5Cfrac%7Bhours%7D%7Bweeks%7D%20%3D%5Cfrac%7Bx%7D%7B12%7D%5Cfrac%7Bhours%7D%7Bweeks%7D%5C%5C%20%5C%5C%20x%3D45%2A12%2F3%5C%5C%20%5C%5Cx%3D180%5C%20hours)
that means------> In three months (12 weeks) the pianist practice 180 hours
Part 2)
Let
x------> the number of bass
y------> the number of catfish
we know that
Using proportion
![\frac{10}{7}\frac{bass}{catfish} =\frac{425}{y}\frac{bass}{catfish} \\ \\y=425*7/10\\ \\y=297.5\ catfish](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B7%7D%5Cfrac%7Bbass%7D%7Bcatfish%7D%20%3D%5Cfrac%7B425%7D%7By%7D%5Cfrac%7Bbass%7D%7Bcatfish%7D%20%5C%5C%20%5C%5Cy%3D425%2A7%2F10%5C%5C%20%5C%5Cy%3D297.5%5C%20catfish)
There are about ![298\ catfish](https://tex.z-dn.net/?f=298%5C%20catfish)
