Answer:
The distance of the playground is 540m
Step-by-step explanation:
Here, we are interested in calculating the length of the playground given the information in the question.
Where to attack the question from is the segment that states that he took a break after 480m and also had 2 breaks. Thus, the distance traveled would be 480 * 2 = 960 m
Now, to find the length of the track, we add the distance covered plus the distance uncovered. Mathematically that would be 960m + 120m = 1,080m
In the last part of the question, we are told that the track is twice as long as the playground. This means that the length of the playground or the distance of the playground is 1080/2 = 540 m
Answer:
x = -1 + 2 sqr2
or
x = -1 -2 sqr2

9514 1404 393
Answer:
$3,840
Step-by-step explanation:
The interest formula can be rearranged to find the principal amount.
I = Prt
P = I/(rt) = $768/(.04·5)
P = $3,840
They originally borrowed $3,840.
