Answer:
The time taken before the police force the robbers off the road is 1.5 hours
Step-by-step explanation:
The speed with which the robbers were travelling = 70 miles per hour
The speed with which the police went after the robbers = 90 miles per hour
The distance with which the robbers were in front of the police before the police came after them = miles
Let t represent the time in hours the police force the robbers off the road, we have;
30 + 70 × t = 90 × t
30 = 90 × t - 70 × t = (90 - 70) × t = 20 × t
30 = 20 × t
20 × t = 30
t = 30/20 = 1.5
t = 1.5 hours
The time taken before the police force the robbers off the road = t = 1.5 hours

7.2 percent of the area of the original hexagon was removed
The area of hexagon is the region that lies within the sides of the hexagon. A hexagon is a two-dimensional shape that has 6 sides, 6 angles, and, 9 diagonals, and the sum of its interior angles is 720°
Area of the hexagon = (3√3 s2)/2, where 's' is the length of the side of the hexagon.
Her, We have
Rationalize the denominator to get
The area of the hexagon is and the dodecagon is
The deleted area is percent
Formula used:
