A circle is 360° all the way around; therefore, if you divide an arc's degree measure by 360°, you find the fraction of the circle's circumference that the arc makes up. Then, if you multiply the length all the way around the circle (the circle's circumference) by that fraction, you get the length along the arc.
Answer:
t = - 24
Step-by-step explanation:
Given t varies inversely as a then the equation relating them is
t = 
← k is the constant of variation
To find k use the condition t = 2 when a = - 4
2 = 
( multiply both sides by - 4 )
- 8 = k
t = 
← equation of variation
When a = 
, then
t = 
= - 24
I believe it is 20 and 15
Answer:
25
Step-by-step explanation:
i am pretty sure this is correct unless your teacher taught you a different way but here is how i found the answer
28+25+22=75
75÷3=25
