She was billed for 1000 minutes. If she gets 300 minutes free, then her bill would be $29.95. But her bill was $99.95, so she was billed $70 worth of the minutes over 300 minutes. $70 divided by $0.10 is 700. Seven hundred minutes plus 300 minutes equals 1000 minutes in total.
Partial products are different in regrouping in terms of how numbers are
clustered from a set equation as a whole delivering it individual but
naturally to all the numbers involved in the set.
Regrouping is just like the commutative or associative property of numbers.
<span>Associative
property of addition is used when you want to group addends. This is
mainly used to cluster set of numbers or in this case, addends. How do
you use the associative property when you break apart addends? Simple
you group them using the open and closed parentheses or brackets. Take
for an example 1 + 1 + 2 = 4. Using the associative property you can
have either (1 + 1) + 2 = 4 or 1 + (1 + 2) = 4 clustered into place. <span>

Answer:
, in degrees
Step-by-step explanation:
The secant of an angle is given by:
![\sec{\theta} = \frac{1}{\cos{\theta}}](https://tex.z-dn.net/?f=%5Csec%7B%5Ctheta%7D%20%3D%20%5Cfrac%7B1%7D%7B%5Ccos%7B%5Ctheta%7D%7D)
In this question:
![\sec{\theta} = -2](https://tex.z-dn.net/?f=%5Csec%7B%5Ctheta%7D%20%3D%20-2)
So
![\frac{1}{\cos{\theta}} = -2](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5Ccos%7B%5Ctheta%7D%7D%20%3D%20-2)
![-2\cos{\theta} = 1](https://tex.z-dn.net/?f=-2%5Ccos%7B%5Ctheta%7D%20%3D%201)
![\cos{\theta} = -\frac{1}{2}](https://tex.z-dn.net/?f=%5Ccos%7B%5Ctheta%7D%20%3D%20-%5Cfrac%7B1%7D%7B2%7D)
In the first quadrant, the angle that has cosine of 1/2 is 60º.
The cosine is negative in the second and in the third quadrant.
The equivalent angle to 60º in the second quadrant is of 180º - 60º = 120º.
The equivalent angle to 60º in the third quadrant is of 180º + 60º = 240º
So the values of
in the interval are:
, in degrees
3147.6 x 25 = 78690 and there’s one decimal place left so add the decimal place and it’s 7869.0 and the 0 doesn’t count so it’s 7869.
