Answer:
9.5 inches per month
Step-by-step explanation:
Given the information about the depth of the pond:
Month 1: 93 in
Month 2: 98 in
Month 3: 112 in
From month 1 to month 3, the average rate of change of the depth of the pond, in inches per month can be calculated using formula
![\dfrac{\text{Depth}_3-\text{Depth}_1}{3-1}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ctext%7BDepth%7D_3-%5Ctext%7BDepth%7D_1%7D%7B3-1%7D)
Hence, from month 1 to month 3, what is the average rate of change of the depth of the pond, in inches per month is
![\dfrac{112-93}{3-1}=\dfrac{19}{2}=9.5\ in/month](https://tex.z-dn.net/?f=%5Cdfrac%7B112-93%7D%7B3-1%7D%3D%5Cdfrac%7B19%7D%7B2%7D%3D9.5%5C%20in%2Fmonth)
Answer:
$14.43¢
Step-by-step explanation:
We are given;
pounds, 1 pound = $4.20 and
pounds,1 pound = $3.80 that Andrea bought.
Now we need to find her total cost. To do that, we must first find the cost of the avocados. To do so, let us set up a graph. But before that is done, convert
to a decimal. It is 1.4. Now we can set up a graph.
<u>Avocados</u>
![\frac{4.2}{1}=\frac{x}{1.4}](https://tex.z-dn.net/?f=%5Cfrac%7B4.2%7D%7B1%7D%3D%5Cfrac%7Bx%7D%7B1.4%7D)
Switch sides
![\frac{x}{1.4}=\frac{4.2}{1}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B1.4%7D%3D%5Cfrac%7B4.2%7D%7B1%7D)
Apply rule: ![\frac{a}{1}=a](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7B1%7D%3Da)
![\frac{x}{1.4}=4.2](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B1.4%7D%3D4.2)
Multiply both sides by 1.4
![\frac{1.4x}{1.4}=4.2\cdot \:1.4](https://tex.z-dn.net/?f=%5Cfrac%7B1.4x%7D%7B1.4%7D%3D4.2%5Ccdot%20%5C%3A1.4)
Simplify
![x=5.88](https://tex.z-dn.net/?f=x%3D5.88)
So, her cost for avocados is $5.88¢
Now we must first find the cost of the avocados. To do so, let us set up a graph. But before that is done, convert
to a decimal. It is 2.25. Now we can set up a graph.
<u>Asparagus</u>
![\frac{3.8}{1}=\frac{x}{2.25}](https://tex.z-dn.net/?f=%5Cfrac%7B3.8%7D%7B1%7D%3D%5Cfrac%7Bx%7D%7B2.25%7D)
Switch sides
![\frac{x}{2.25}=\frac{3.8}{1}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B2.25%7D%3D%5Cfrac%7B3.8%7D%7B1%7D)
Apply rule : ![\frac{a}{1}=a](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7B1%7D%3Da)
![\frac{x}{2.25}=3.8](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B2.25%7D%3D3.8)
Multiply both sides by 2.25
![\frac{2.25x}{2.25}=3.8\cdot \:2.25](https://tex.z-dn.net/?f=%5Cfrac%7B2.25x%7D%7B2.25%7D%3D3.8%5Ccdot%20%5C%3A2.25)
Simplify
![x=8.55](https://tex.z-dn.net/?f=x%3D8.55)
So, her cost for asparagus is $8.55¢
<u>Total cost</u>
Now that we have found out how much both of the fruits Andrea bought costs, we need to sum it up (meaning add it) to find the total cost:
$5.88¢ + 8.55¢ =
5.88 + 8.55 = 14.43
Therefore, Andrea's total cost of the fruits is $14.43¢
17. C
I'm not sure about the others :/
<span>y = x – 3
slope = 1
y-intercept = -3
so the answer is C. </span><span>slope: 1, y-intercept: –3</span>
