Step-by-step explanation:
y = 300x + 2200
Answer:
It will take the train 1.2375 minutes to pass the tunnel
Step-by-step explanation:
Mathematically, we know that ;
time = distance/ speed
The distance here is the length of the train which is 132 m ; we can convert this to km by dividing by 1000
We have this as 132/1000 = 0.132 km
So, we have the time as;
0.132 km/6.4 km/hr = 0.020625 hr
Mathematically, we know that 60 minutes make an hour;
so we have
0.020625 * 60 = 1.2375 minutes
In the first problem you have a triangle defined by two 8 cm radii and a 120 degree angle. You could use the Law of Cosines to determine the length of the longest side, x.
x^2 = 8^2 + 8^2 - 2(8)(8) cos 120 deg.
Can you finish this?
According to my knowledge, that mixed number already is in its simplest form. Turn it back into a fraction and it isn't divisible. A mixed number and 3 can't be divided perfectly by 8 or anything in common. So 4 3/8 is already in it's simplest form.
