Answer:
900
Step-by-step explanation:
Because the unit rate of mins per mile is 7.5 min for each mile. So, then you multiply 120 with 7.5 and move the decimal place to get
2700 (1-4%) 5. population by 2020 would be 2201

Answer:
a + b + c + d + e = 180.
Step-by-step explanation:
We can prove that a = angle CBA (vertically opposite angles are equal).
Now, since lines DE and CA are parallel, then it follows that c = angle ACE (alternate angles are equal). Similarly, b = angle CAD.
But notice that what we've just done is found the angles of the triangle CBA.
So the sum of the angles (a + b + c + d + e) is the sum of the angles of a triangle.
We then conclude that a + b + c + d + e = 180 degrees.
