If the diameter is 1/2 mile, that is 0.5 mile, then the radius is 0.25 -half of it!
the angular speed is theta/time, which means
w=theta/time
but another formula for it is Velocity*radians
w=velocity*radians
velocity is 180 mph and radians are (revolution/2

radius), that is:
w=180*(1/2

*0.25)
and if we calculate this, we have: w=114.59, which is the correct answer!

Answer:</h3>
-y³ -6y²x +30
<h3>
Step-by-step explanation:</h3>
When parentheses are eliminated and the y variable placed first in each term, the expression simplifies to ...
... 15 -7y²x -y³ +y²x +15
Arranging like terms together, we have ...
... -y³ +y²x(-7 +1) +(15 +15)
... -y³ -6y²x +30
_____
The two different 3rd-degree terms can be expressed in either order. I have chosen to list the term with the largest exponent first. The expression could also be written with the same-degree terms in "lexicographical order", meaning the expression would be written ...
... -6xy² -y³ +30
Answer:
13/30
Step-by-step:
First, you find the common denominator, which is 30. For the first fraction, multiply the bottom by five. Since you do that, you have to multiple the top by 5 as well, giving you 25/30. For the second problem, you multiple the top and bottom by six giving you 12/30. 25 minus 12 is 13 so you get 13/30.

<span>0.002
is the 1/10 of what number.
Find the number that applies to this.
=> 0.002 has a thousandths value since it is placed next to the decimal
points
=> To be able to get the answer. Let’s convert 1/10 into a decimal.
=> 1 / 10 = 0.1
Now that we have the same decimal numbers, we can now start dividing 0.1 to
0.002
=> 0.002 / 0.1
=> 0.02
Thus, 0.002 is the 1/10 of 0.02 number.</span><span>
