Answer:
11.6% decrease (rounded off to the nearest tenth)
Step-by-step explanation:
Population decrease = 5,416,000 - 4,787,000 = 629,000
Percentage decrease = (decrease ÷ original population) × 100
Percentage decrease =
× 100 = 11.61373708%
Or 11.6% decrease (rounded off to the nearest tenth)
A rectangle has two couples of equal sides, so a soccer fields has two 80-meters sides and two 120-meters sides.
This leads to a perimeter of

If you go around it twice, you'll run 800 meters
The answer is $84.29
Let the number of minutes be x.
$35.99 is fixed price and does not depend on the number of minutes x. Each minute costs $0.21 so it depends on x and we have 0.21x in the function. However, 250 minutes are already included and should not be included in x. Therefore, the function that represents the monthly cost looks like this:
f(x) = 35.99 + 0.21 * (x - 250)
Now, let's calculate for x = 480 minutes:
f(480) = 35.99 + 0.21 * (480 - 250)
f(480) = 35.99 + 0.21 * 230
f(480) = 35.99 + 48.30
f(480) = 84.29
