-- If one train covers 40 km per hour and the other one covers 60 km per hour,
then they reduce the gap between them at the rate of 100 km per hour.
-- Since they begin 30 km apart, they meet and crush the crow in 30/100 = 0.3 hour.
-- The crow's speed is 80 km per hour. In 0.3 hour, he covers 0.3 x 80 = <em><u>24 km.</u></em>
<u>Note:</u> 40 km/hr and 60 km/hr are speeds, not velocities.
Product means multiply, so the product of 12 and 8 would be written as 12 x 8
Then you want 6 less than that so you need to subtract 6
The equation should look like (12 x 8) - 6
(1,2/3)(-1,-1)
slope = (-1 - 2/3) / (-1-1) = (-3/3 - 2/3) / -2 = (-5/3)/-2 = -5/3 * -1/2 = 5/6
y = mx + b
slope(m) = 5/6
(-1,-1)...x = -1 and y = -1
now we sub
-1 = 5/6(-1) + b
-1 = -5/6 + b
-1 + 5/6 = b
-6/6 + 5/6 = b
-1/6 = b
y = 5/6x - 1/6 <=== ur equation
Answer:
6 degrees
Step-by-step explanation:
x + 12x + 17x = 180
x = 6
The angles are 6 : 72 : 102 so the smallest is 6 degrees.
