Answer:
answer: 31.4
Step-by-step explanation:
the formula to finding circumference is just diameter × pi we arent given the diameter so we have to figure it out but what we do know is the radius is half of the diameter so 5 x 2 = 10 so now that we have the diameter we just multiply by pi so 10 × 3.14 = 31.4 Hope this helps!
<span>Let's called the train that traveled south train A, and the train that traveled east train B
After 3 hours, train A is 180 miles South
and Train B is 150 miles East
Using Pythagoras, distance between is sqrt(180^2 + 150^2)
30 sqrt(6^2 + 5^2) = 30sqrt(36 + 25) = 30sqrt 61 = 234.307 miles</span>
Answer:
b=-1
Step-by-step explanation:
1=(6/-15)(-5)+b
-6/15=-2/5
(-2/5)(-5)=10/5=2
2+b=1
b=1-2=-1
Answer: Linear pair is a pair of two supplementary angles. But two supplementary angles might or might not form a linear pair, they just have to "supplement" each other, that is their sum should be 180°, thus the Answer is B: Sometimes
