Answer:
$2160
Step-by-step explanation:
Here we are going to use our simple interest formula. We know that p=2000,t=1, and r=8/100=0.08 Once again, lets replace those values in our formula: A=2000(1+(0.08)(1)) A=$2160
Answer:
D i think
Step-by-step explanation:
Is there a picture of the problem I can help
Let x be the length of the train.
On the basis of the observer;
Speed of the train = x/6
On the basis of the bridge;
Total distance covered by any point of the train= 350+x
Speed = (350+x)/20
Equating the two expressions of speed;
x/6 = (350+x)/20
20(x) = 6(350+x)
20x = 2100+6x
(20-6)x = 2100
14x = 2100
x= 2100/14 = 150 m
Speed = x/6 = (350+x)/20 = 150/6 = 500/20 = 25 m/s.
Therefore,
Length of train = 150 m
Speed of train = 25 m/s
Answer:
$30
Step-by-step explanation:
divide 600 by 10 to get 60
divide 600 by 4 to get 150
divide 600 by 5 to get 120, then multiply 120 by 3 to get 360.
600-60-150-360=30
