As an estimation we are told 5 miles is 8 km.
Convert 72 km to miles.

45 miles

Step-by-step explanation:

5 miles = 8 km

72 km = 9 * 8 km

Since 8 km = 5 miles, replace 8 km with 5 miles

72 km = 9 * 8 km = 9 * 5 miles = 45 miles

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
