divide the KM speed with 1.61 because 1 mile equals 1.61 KM
Answer:
C. 21°
Step-by-step explanation:
In triangle ABC, perpendiculars dropped on the sides AB and AC from the ray BD are equal in measure or congruent.
Therefore, ray BD is equidistant from the sides AB and AC.
So, ray BD will be the bisector of angle ABC.
(Angle bisector theorem)
Answer:
y = -2/3x - 2
Step-by-step explanation:
Step 1: Find slope <em>m</em> of perpendicular line
<em>Simply take the negative reciprocal of the given line</em>
m = -2/3
y = -2/3x + b
Step 2: Find <em>b</em>
6 = -2/3(-12) + b
6 = 8 + b
b = -2
Step 3: Rewrite perpendicular equation
y = -2/3x - 2
So the equation would be 4x+x=30. So since they have the same variable, x and 4x, you add them together to get 5x=30. Then you divide by both sides and get x=6. So there are 6 spaniels.
Distance = 30 mi
Speed = 45 mi/h
We know that Distance = Speed x Time OR Time = Distance/Speed
Time to go to the site: T = 30/45 = 0.66667 Hour. Multiply by 60 to get it in minutes: 0.66667 x 60 = 39.9999 ≈ 40 minutes
To come back he also spent the same time or 40 minutes
To and Fro = 80 minutes or 1 H 20 minutes
