you take 2pi and divide it by bits stolen from the equation its explained more in the screennshot
Actually Welcome to the concept of Radioactive decay.
So the left would be 30 grams.
(v+4)t=66
t=66/(v+4)
...
(v-4)t=42, using t found above in this equation gives you:
66(v-4)/(v+4)=42 perform indicated multiplication on the left side
(66v-264)/(v+4)=42 multiply both sides by (v+4)
66v-264=42v+168 add 264 to both sides
66v=42v+432 subtract 42v from both sides
24v=432 divide both sides by 24
v=18
So his normal bicycling speed with no wind is 18 mph.

Step-by-step explanation: All you have to do is 15-6=
Answer:
120
Step-by-step explanation:
Let's say you put them on the shelf one by one, from left to right.
You can pick 1 of the 5 for the first position.
5
Now you have 4 books left. You pick one out of those 4 for the second position.
5 * 4
There are 3 choices left for the 3rd position.
5 * 4 * 3
2 left for the 4th position.
5 * 4 * 3 * 2
Finally, there is one book left for the 5th position.
5 * 4 * 3 * 2 * 1
Now we multiply:
5 * 4 * 3 * 2 * 1 = 120
