Circumference: 6.28319 km. Area: 3.14159 km
Step-by-step explanation:
P(black or yellow) = P(black) + P(yellow) − P(black and yellow)
P(black or yellow) = 1/25 + 1/5 − 0
P(black or yellow) = 6/25
Answer:
the measurements must be incorrect because when you solve it, it is obvious that 6x is not a 90 degree angle and 3x is not 45 degrees.

Step-by-step explanation:
Let be the cost of renting from Mozart's Music Store for years, and be the cost of renting from Bach's Music Store for years.
From the problem statement, we can come up with the following equations:
Plugging in for each equation, we can get the answer:
From this, we can see that the value is equal for both stores.
Initial amount, .
Final amount, .
Time taken, t = 6:00 - 2:00 = 4 hour.
We know,
Therefore, the half-life of the isotope is 1.024 hours.
Hence, this is the required solution.
