Answer: Both trains would meet at 1 pm
Step-by-step explanation:
Let t represent the time at which both trains will pass each other.
The distance between the cities is 360 miles. This means that by the time both trains meet, the total distance covered would be 360 miles.
Distance = speed × time
The freight train is travelling at 50 mph. Distance covered by the freight train in t hours is 50t.
The passenger train is travelling at 70 mph. Distance covered by the passenger train in t hours is 70t.
Since the total distance covered is 360 miles, it means that
50t + 70t = 360
120t = 360
t = 360/120
t = 3 hours
Both trains would meet at 1 pm
A triangle's interior angles will always add up to 180 degrees.
When one interior angle gets larger, the other angles must decrease in size.
If you attempt to make a triangle with two obtuse angles, you will find you can't do it in three lines. But you need an extra line in order to close the shape. But it won't be a triangle.
A equals to 2.
<u>Step-by-step explanation:</u>
y = mx + c is the equation of the line and m is the slope and c is the y- intercept.
In the given equation, y = ax , a is the slope.
Slope A can be found by means of the formula, and using the points (2,4) and (-2-4)
slope, A = (y₂ -y₁) / (x₂-x₁)
Plugin the values as,
A = (-4-4) / (-2-2) = (-8) / (-4) = 2
So the value of A is 2.
4(2x5 + 3) - 4(2) + 2(5).
4(13) - 18.
52-18 = 34.
