Answer:
Distance of Tunnel is 500 meters + Train travel rate is 20 meters per second = 25 seconds to pass through the tunnel only therefore the outstanding balance of 35 seconds x 20 meters per second =600 meters Train
Step-by-step explanation:
Total of length of train 600 meters and tunnel (500 meters) is 1,200 meters +30 seconds = TR of 20 meters per second
Answer:
b = 22 m
Step-by-step explanation:
The formula for calculating the area (A) of a triangle is
A = 
bh
multiply both sides by 2 to eliminate the fraction
2A = bh ( divide both sides by h )
b = 
, hence
b = 
= 
= 22 m
Answer:
y = -2/5x + 2
Step-by-step explanation:
Answer
If only {2y(z-1)} is being divided by two:
9x+9+yz-y
If whole equation is divided by two:
9x+9+2yz-2y over 2
Explanation: In the first instance, you can cancel out the 2 in the numerator and denominator, which leaves you 9(x+1) + {y(z-1)}. You can then simplify to get 9x+9+yz-y
In the second instance, you distribute 9 to what is inside the parentheses, and get 9x+1. You then distribute 2y to what is inside the parentheses within the brackets and get 2yz-2y. You are then left with 9x+9+2yz-2y over 2
Answer:
-2y+4x
