A building has two elevators that both go above and below ground. At a certain time of day, the travel time it takes elevator A to reach height h
in meters is 0.8h+ 16 seconds.
The travel time it takes elevator B to reach height h in meters is -0.8h +12
seconds.
1.
What is the height of each elevator at this time?

the answer

b. they are parallel and will never intersect.

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two

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
