Answer: x - 2.6 = 72.8
x is the number which Dan was thinking (x > 2.6)
we have:
x - 2.6 = 72.8
Step-by-step explanation:
Divide 315,530,612 by 3,539,225 to get 89 people per square mile (rounded)

Answer:
The dollar amount of the meals Sarah served was $1150.
Step-by-step explanation:
Set up an equation expressing Sarah's total earnings:
(total earned) = (base wage) + 0.15 * (price of meals served)
Now the same using what we know:
$252.50 = $80 + 0.15 * x
where x is unknown and can be solved for:
x = (252.50 - 80) / 0.15 = $1150
The dollar amount of the meals Sarah served was $1150.
We will use the Cosine rule ( graph is in the attachment ):
c - the displacement
Angle: 90° + 45° = 135°
c² = a² + b² - 2 ab cos 135°
c² = 98² + 225² - 2 · 98 · 225 · ( -0.7071 )
c² = 9,604 + 50,625 + 31,183.11
c² = 91,412.11
c = √ 91,412.11
c = 302.344 km
