Answer: 4 pounds > 60 ounces (D)
Step-by-step explanation:
Since there are 16 ounces in a pound, you just multiply 16 (ounces) by 4 (pounds). If you evaluate 16*4, you would get 64 ounces, so 64 is greater than 60. So the answer is D.
Answer:
![(x+5)^{2} +(y+4.7)^{2} = 274](https://tex.z-dn.net/?f=%28x%2B5%29%5E%7B2%7D%20%2B%28y%2B4.7%29%5E%7B2%7D%20%3D%20274)
Step-by-step explanation:
Put the xs together
![x^{2} +26x + y^{2} -22y+274=0](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%2B26x%20%2B%20y%5E%7B2%7D%20-22y%2B274%3D0)
move the 274 to the other side, and that will be the ![r^{2}](https://tex.z-dn.net/?f=r%5E%7B2%7D)
![x^{2} +26x + y^{2} -22y=274](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%2B26x%20%2B%20y%5E%7B2%7D%20-22y%3D274)
you need
and ![y^{2}](https://tex.z-dn.net/?f=y%5E%7B2%7D)
so square root 26 is 5.09, so about 5 when rounded
![(x+5)^{2}](https://tex.z-dn.net/?f=%28x%2B5%29%5E%7B2%7D)
and square root 22 is 4.69, so about 4.7 when rounded
![(y+4.7)^{2}](https://tex.z-dn.net/?f=%28y%2B4.7%29%5E%7B2%7D)
so ![x^{2} +26x + y^{2} -22y+274=0](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%2B26x%20%2B%20y%5E%7B2%7D%20-22y%2B274%3D0)
becomes ![(x+5)^{2} +(y+4.7)^{2} = 274](https://tex.z-dn.net/?f=%28x%2B5%29%5E%7B2%7D%20%2B%28y%2B4.7%29%5E%7B2%7D%20%3D%20274)
30 miles because it is 10 miles per hour.
Answer: y=2x-1
y=-x+18
y=2x-1 is the perpendicular
