on a recent trip, a trucker traveled 420 mi at a constant rate. Because of road conditions, the trucker reduced the speed by 30mi. An additional 40 mi was traveled at the reduced rate. The entire trip took 7 hours. Find the rate of the trucker for the first 420 mi.

step-by-step explanation:

table 3 represents a direct variation function. : )

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

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
