ACTIVITY RESULTS Select the letter of the correct answer.
In traffic lights, LED bulbs use about 90% less energy than incandescent bulbs. Let's say that
an incandescent bulb uses 240 units of energy. If this is true, how much energy does an LED
bulb use?
Hint
A 15 units
B 20 units
C 33 units
D 24 units

step-by-step explanation:

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?

step-by-step explanation:

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
