Answer: the two trains will meet in 2.8 hours
Step-by-step explanation:
Step 1
Speed of train A = 90mph
Speed of train B = 110 mph
Since both trains are travelling towards each other
, their effective speed will be= 90 mph + 110mph= 200mph
Step 2
we know that Speed = distance / time
therefore Time = Distance / speed
Distance = 560 miles
Speed = 200 mph
Time = 560miles / 200mph
2.8 hours
The answer of your problem is C. Because 25 and 100 are related integers.
Mass=Density*Volume
Density=1.1 g/cc
Volume of a cylinder: <span>π*r^2*h
</span>Radius of the top of the can: 3.57
Volume of this can: 480.47
480.47*1.1=528.517
If I'm correct the mass of this can should be 528.517
Answer:
ayy I gotchuu
Step-by-step explanation:
theres gonna be two solutions
a negative then positive
positive:
|3x - 9| = 12
3x-9=12
3x=21
x=7
negative:
3x-9=-12
3x=-3
x=-1
