Answer:
2 minutes
Step-by-step explanation:
The front of the train enters the tunnel and travels 1 km before the rear of the train enters the tunnel. Thus, the total distance traveled by the front of the train is 2 km, and this is covered in a certain number of hours:
Since distance = rate times time, time = distance / rate. In this particular case we have:
2 km
time = distance / rate = ------------------- = (1/30) hr
60 km/hr
(1/30) hr converts to 2 minutes, since 1 hr = 60 minutes
Answer:
y=1/2x
Step-by-step explanation:
The slope of the line goes up by 1 over by 2 each time or 1/2. (Rise over run)
This can be proven by substituting X and Y for a point on the graph.
y=5, x=10
5=1/2(10)
5=5
The value of the expression as described in the task content is; 11.
<h3>What is the value of the expression?</h3>
The expression as described in the task content is; 3(4 - N) +8.
However, the value of N in this scenario is; 3.
Therefore, the value of.the expression is;
3(4 - 3) +8
= 3(1) + 8
= 3+8
= 11.

Answer:
triangle ABC is "not" a right-angled triangle
Step-by-step explanation:
AB=8cm
BC=5cm
perimeter = 22cm
CA = 22 - 8 - 5 = 9
8² + 5² = 89
9² = 81
AB² + BC² ≠ CA²
I hope this picture helps, but next time try to chose a number to cancel out the fraction. Example, y=1/3x+4 chose 3,6,9 and other multiples of 3.
