When a tangent (top line with the arrow) and a secant (other line) intersect, they form an angle (55°) equal to:
55° = ½ (the larger intercepted arc minus<span> the smaller intercepted arc)
</span>
<span>55° = ½ (170° -x°)
55° = 85° -</span><span>½ x
</span><span>½ x = 30°
x = 60°
</span>

This question requires you to know the lowest common multiple (LCM) of 5, 4 and 2. there are a few ways to do that. in this case the LCM would be 20. this means that in 20 year the science department would buy all 3 equipment at the same time
Answer:
Malcolm would logically be running at 4.75 and since he is running at 3, it would be the lowest possible therefore its B
Step-by-step explanation:
First, group them in 2's (2 numbers per group)
and see which ones have the factors of each other
you want to group 12x^3 with 3x because 3 is a factor of 12
then you want to group -20x^2 and -5 together becuase 5 is a factor of 20 so
(12x^3+3x)+(-20x^2-5)
undistribute
(3x)(4x^2+1)+(-5)(4x^2+1)
revese distribute (ab+ac=a(b+c))
(3x-5)(4x^2+1)
