A=10*8+((8-6)(15-10))/2
A=10*8+(2*5)/2
A=10*8+10/2
A=10*8+5
A=80+5
A=85 feet
Therefore the answer is D
Hope this helps :)
Answer:
r = 0.0424 cm (3sf)
Step-by-step explanation:
it makes 150 rev/sec
1 revolution = 1 circumference = 2pi*r
so every second the spool goes through 2*pi*r*150 of distance
we know that the rate of pulling is 40cm/sec
so 2pi*r*150 = 40
r = 40/(2pi*150), which is 0.04244131816 cm.
check: Circumference is 2pi*r = 0.2666
now multiply by 150rev/sec = 40 cm/sec
Johnny now has 90 so Jeana did not take 25 she only took 10
