Answer: (-28,-4)
Step-by-step explanation:
Multiply the x and y coordinate values by the scale factor to find the image.
-7 * 4 = -28
-1 * 4 = -4
(-28,-4)
The net force is what remains of the pull when we subtract the friction force:
![F = 64-36 = 28N](https://tex.z-dn.net/?f=F%20%3D%2064-36%20%3D%2028N)
Now, use the law
![F=ma](https://tex.z-dn.net/?f=F%3Dma)
and solve it for the acceleration
![a = \dfrac{F}{m}](https://tex.z-dn.net/?f=a%20%3D%20%5Cdfrac%7BF%7D%7Bm%7D)
to get the result:
![a = \dfrac{28}{14}=2](https://tex.z-dn.net/?f=a%20%3D%20%5Cdfrac%7B28%7D%7B14%7D%3D2)
Answer:
42%
Step-by-step explanation:
x is for the volume of the container
the amount filled in the first container=0.30x
the volume of the first container + 50% of the second=(x+x*50%)=1.5 x
the amount of acid in the second container= 1.5x * 50%=0.75x
total amount of acid in the third one =0.3x+0.75x=1.05x
total solution : x+1.5x=2.5x
percentage=1.05x/2.5x= 0.42 or 42%
