Kathleen is standing 150 feet away from a hot air balloon before it takes off. When the balloon reaches a height of h feet, the distance, d, between Kathleen and the balloon is given by
d=150? + ? How many feet high is the balloon when Kathleen's distance from it is 250 feet?

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.

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
