Answer:
a= 6
b = 7
c = 8
d = 7
e = 6
Step-by-step explanation:
Notice that the bike is 6 feet above the ground to start with, so when it starts rolling, the green dot is exactly 6 feet from the ground, which gives a=6
when the distance covered by the bike is 
, (see first red dot in the attached image), the position of the green dot is exactly 1 foot added to 6 ft= 7 feet
so b = 7
when the distance covered is 
, now the green dot would be at the top of the wheel (second red dot in the attached image) which involves adding 2 feet to the original 6 feet. That is: c = 8
when the distance covered is 
, the green dot is at the position of the third red dot in the attached image., that it exactly one foot added to 6 feet = 7 ft which gives the value of d = 7
and finally, when the distance covered is 
. the green dot has completed a full circle and is now again in its lower position (nothing - zero) added to 6 feet = 6ft, giving e = 6.
Answer:
No sé si este es un problema de opción múltiple, pero tanto (A) como (B) son fracciones equivalentes.
Step-by-step explanation:
Answer:
To begin this problem we call "the sum of the number" x. Now we have the equation 2(x)+5=20. This is the answer because it said to translate the equation. I think 2x+5+20 would be the correct translation.
Answer:
a. 17.03 mi/hr b. 0 mi/hr or 18.99 mi/hr c. 17.03 mi/hr
Step-by-step explanation:
Av Vel =(V1+V2)/2 =26
Av Speed =d/t=55=> d=55t1
D=d+d 2d =2(55t1)=110t1
av Vel =110ti/(t1+t2)
t2=3.23t1 => total time =4.23 t1
a. V2=55t1/3.23t1 =17.03 mi/hr
b. velocity as vector quantity (v2-v1)/2 =18.88 or displacement d-d=0 and av velocity = (d-d)/2= 0/2
c. since all information are standing but opposite direction which doesn't affect speed as scalar av speed is the same
