Answer:
11 meters distance.
Step-by-step explanation:
The dolphin went from -6 to positive 5.
-6+11=5
L= length
W= width= 9 yards
Perimeter= 72 yards
Plug in the numbers you know and solve for L.
Perimeter= 2L + 2W
72= 2L + 2(9)
72= 2L + 18
subtract 18 from both sides
54= 2L
divide both sides by 2
27= L
CHECK:
72= 2(27) + 2(9)
72= 54 + 18
72= 72
ANSWER: The length is 27 yards
Hope this helps! :)
Answers:
1: 6, because both are congruent
2: 14, because if half is seven then the whole line is double.
3: (Sorry, I’m not sure on this one).
4: Right triangle
5: 42, because A = (xy) / 2
<h3>given:</h3>
circumference= 14
<h3>to find:</h3>
the radius of the circle.
<h3>solution:</h3>
![r = \frac{c}{2\pi}](https://tex.z-dn.net/?f=r%20%3D%20%20%5Cfrac%7Bc%7D%7B2%5Cpi%7D%20)
![r= \frac{14}{2 \times \pi}](https://tex.z-dn.net/?f=%20r%3D%20%20%5Cfrac%7B14%7D%7B2%20%5Ctimes%20%5Cpi%7D%20)
![r = 2.22817](https://tex.z-dn.net/?f=r%20%3D%202.22817)
![r = 2.23](https://tex.z-dn.net/?f=r%20%3D%202.23)
