Answer:
$ 12400
Step-by-step explanation:
P =$10,000
r= 10%
t = 3 year
I = $ 2400
Amount = P + I = 10000 + 2400 = $ 12,400
x and 4x are supplementary to each other, meaning they add up to 180. So your equation is 180=5x. Divide both sides by 5 to get 36=x.
Answer:
Step-by-step explanation:
To answer this problem, we must bear in mind that the express train travels 3 times faster than the freight train.
If we call F the distance that the freight train travels and we call E at the distance that the express train travels, we must have the distance between them after 15 minutes it must be 30 miles.
So
We also know that:
Since the express train travels 3 times faster than the freight train.
So, like both equations, we have to:
Then miles in the opposite direction.
This is the distance you traveled in 15 minutes.
Therefore, the speed of the express train () is the distance traveled between the time it did
Answer:
Step-by-step explanation:
For a polygon of N sides, the sum is
N*(180-360/N) = N*180 - 360 degrees
Subtract (120 +93 +108 +101) from 540 for your answer
