It should take 45 minutes. 18/12=1.5
30 times 1.5 is 45
Answer:
4.2 miles
Step-by-step explanation:
Using the pythagorean theorem, a^2 + b^2 = c^2
youll get 3.6^2 + 2.2^2 = 17.8
sqrt of 17.8 = 4.2
Answer:
90°
Step-by-step explanation:
Circle C has radius √36 = 6
Circle D has radius √18 = 3√2
As the D radius intersecting either point of tangency, does so at a right angle.
The half angle θ between the tangents is
sinθ = 3√2 / 6 = ½√2
θ = 45°
so the angle between the tangents is 2(45) = 90°
M = 25 - 31 / 3 - 4
m = - 16 / - 1
m = 16
25 = 16(3) + c
c = 25 - 48
c = - 23
y = 16x - 23
