Answer:
< BCA = 70
Step-by-step explanation:
The complete central angle of a circle is 360 degrees. The given portion is 250 degrees.
What is left over? BOA = 360 - 250 = 110
Tangents always meet the radius at 90 degrees. Since there are two tangents <CAO = <BAO = 90 degrees.
So piecing it all together, the equation becomes
<BAO + CAO + BAO + ACB = 360
110 + 90 + 90 + <ACB = 360
290 + <ACB = 360
<ACB + 290 - 290 = 360 - 290
ACB = 70 degrees
Answer: 
Step-by-step explanation:
1. By definition, an inverse variaton is a relationship between two variables:
- When of them increases, the other one decreases.
- When one of them decreases, the other one increases.
2. An inverse variation has the following form:
(
is inversely proportional to 
)
Where 
is a nonzero constant.
3. The option that has the form shown above is:
Where 
is the nonzero constant.

Answer:
hotogs=$1.50 hamburgers=$1
Step-by-step explanation:
h=hotdog b=hamburger
7h+4b=13
4h+7b=14.5
(7h+4b=13)-4b
4h+7b=14.5
h=-0.57b+1.86
4h+7b=14.5
