Answer Answer R= 2(G-6)

:G=19

G=.5R+6

19=.5R+6

-6=.5R-6

13.=.5R

Divide by 5

R= 26

Answer:

r = 2(19-6)

Step-by-step explanation:

19 is the number of green. 19 also is equal to (r/2 + 6)

so 19 = r/2 + 6   rearrange for R = 2( 19-6)

subtract 6 from both sides, then multiply by 2 to cancel the denominator.

19 -6 = r/2     13 = r/2

2(13) = r

r =26

While passing a slower car on the highway, i accelerate uniformly from 12 m/s to 24 m/s in a time of 10.0s. How far do you trave
Taya2010 [7]
You say that there is uniform acceleration so:

vf-vi=at  (final velocity minus initial velocity is equal to acceleration times time)

We know vf, vi, and t so we can solve for acceleration:

24-12=a10

12=10a

a=1.2

That is the acceleration, we will need to integrate with respect to time twice...

v=⌠a dt

v=at+vi  , we know a=1.2m/s^2 and vi=12m/s

v=1.2t+12, 

x=⌠1.2t+12 dt

x=1.2t^2/2+12t+xo, we can just let xo=0 for this problem...

x(t)=0.6t^2+12t

Now we know that this acceleration lasts for 10 seconds so the distance traveled in that time is:

x(10)=0.6(10^2)+12(10)

x(10)=60+120

x(10)=180 meters

How much string would you need to go around the bottom of a hat shaped like a cone if the radius is 4 inches? (Use 3.14 for π)
Softa [21]

Answer:

25.12 inches

Step-by-step explanation:

To find the circumference or the perimeter of a circle it is the diameter times pi. (pi = 3.14) Or you can do radius times 2 times pi.

Answer is 4 times 2 times 3.14 which is 25.12
