we know that
The time it takes for the train to pass a single post is equal to the time it takes for the train to pass its length.
the length of the train is-----> 375 m
<u>convert to Km</u>
1 Km =1,000 m
375 m=375/1,000=0.375 Km
the speed of the train is 45 km/hour
so
by proportion
<u>convert to minutes</u>
1 hour=60 minutes
0.0083 hours=0.0083*60=0.5 minutes
<u>convert to seconds</u>
1 minute=60 sec
0.5 minutes=0.5*60=30 sec
therefore
<u>the answer is</u>
30 seconds
Ok circumference= 2pi r. So r= 32.5. Area = pi*r*2 do the answer should be either C or D
Part A: 7/10 because .7 represents 70/100 of a whole, or 7/10.
Part B: I think 1 and 89/100 because 89/100 represents that fraction
These are my answers, so I may be wrong.
Hope I helped, and good luck!
No.
0.3^4 or 0.3x0.3x0.3x0.3= 0.0081
0.9^2 or 0.9x0.9=0.81
These are not equivalent.
Answer:
x=11.6
Step-by-step explanation:
According to the angle addition postulate, if B lies on AC, than AB+BC=AC.
We can use this to create this equation.
x+12+2.4=26 Where x+12 is the value of AB and 2.4 is BC.
The next step is to combine like terms, so we add 12 to 2.4 to get
x+14.4=26. When trying to find the value of a variable, you must isolate it. To do this for this equation, we must subtract 14.4 from both sides which will give you.
x=11.6
Hope this helps. If you have any follow-up questions or I misunderstood the question, please tell me and I will fix it or explain more.
Have a great day! :)
