Im pretty sure you put the wrong picture. The slope isn't negative and there is no point O,A, or B.
Answer:
31
Step-by-step explanation:
x+24+4x+1=180
5x+25=180
5x=155
x=155/5=31
The answer is a.0
Concentric means these circles would have the same center, thus, the smaller circle must be inside the bigger circle. Any tangent line to the smaller circle wont be a tangent line to the bigger circle, since that tangent line would intersect at the bigger circle at 2 points. Any tangent line to the big circle will not touch the small circle... so the answer would be 0.
Answer:
136 minutes
Step-by-step explanation:
Given :
2 miles ----> takes 17 min
1 mile -----> takes 17/2 min
hence the unit rate is (17/2) min per mile
Thus, 16 miles will take
= (17/2) miles per min x 16 miles
= (17/2) x 16
= 136 minutes
The answer would be 212,I can't completely explain why because I did it the long way which took me over an hour to do.
