Answer:
Option A. (-16,14)
Step-by-step explanation:
we know that
The formula to calculate the midpoint between two points is equal to
![M(\frac{x1+x2}{2},\frac{y1+y2}{2})](https://tex.z-dn.net/?f=M%28%5Cfrac%7Bx1%2Bx2%7D%7B2%7D%2C%5Cfrac%7By1%2By2%7D%7B2%7D%29)
In this problem we have that
![point\ Q(x1,y1)\\point\ A(x2,y2)](https://tex.z-dn.net/?f=point%5C%20Q%28x1%2Cy1%29%5C%5Cpoint%5C%20A%28x2%2Cy2%29)
![(-2,10)=(\frac{x1+12}{2},\frac{y1+6}{2})](https://tex.z-dn.net/?f=%28-2%2C10%29%3D%28%5Cfrac%7Bx1%2B12%7D%7B2%7D%2C%5Cfrac%7By1%2B6%7D%7B2%7D%29)
so
---> ![x1=-4-12=-16](https://tex.z-dn.net/?f=x1%3D-4-12%3D-16)
---> ![y1=20-6=14](https://tex.z-dn.net/?f=y1%3D20-6%3D14)
therefore
The coordinates of point Q are (-16,14)
To solve this problem, we simply need to identify the variables, where sunflowers are "s" and other flowers can be "f". Since we know that there are 8 rows of "f" for every 2 rows of "s", we can find that s=4f. This can lead to the equation:
2s+8f=240; or, when substituted, 2(4f)+8f=240.
We can solve this equation as 16f=240, or f=15.
Now, we can put f into s=4f, and find that s=60. So we can subtract the total number of rows by 60 to find the total number of "f" rows.
240-60=180.
This means that there are 180 rows that are NOT sunflowers.
Hope this helps!
It's simple!
Because that a composite figure is made of other / combining rectangular prisms, you can find the composite figure's volume by finding the volumes of those combined rectangular prisms and adding them up.
