Answer:
Ken can walk 40 dogs in 8 hours.
How many dogs can Ken walk in 12 hours?
Step-by-step explanation:
1 - ( 2/3 + 1 /4 ) =
= 1 - ( 8 / 12 + 3 / 12 ) =
= 1 - 11 / 12 = 12 / 12 - 11 /12 = 1 /12
Answer:
1 / 12 of the girls in class have neither blue or brown eyes.
So 1 and 1/3 times 5/6
first convert 1 1/3 into improper fraction (x/y)
1 1/3=3/3+1/3=4/3
4/3 times 5/6=(4 times 5)/(3 times 6)=20/18=10/9
the answer is 10/9 or 1 and 1/9 or 1 1/9
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°
