If the perimiter of a sector is 4 times its radius, then the radian measure of the ceenral angel of the sector is

The perimeter of a sector includes two segments that are each equal to the radius, and the arc length. For your sector, the arc length is found as
   perimeter = 4r = r + r + arc-length
   2r = arc-length

Now we also know that arc-length is related to the central angle (in radians) by
   arc-length = r*central-angle
   2r = r*central-angle
   2 = central-angle

The measure of the central angle of the sector is 2 radians.

93 is the sum of a number g and 58
Wewaii [24]
Assuming you are hoping to obtain the value of "g", to solve worded algebra problems like these, it is easier to translate the world problem into a mathematical equation first.

In this case, "93 is the sum of a number g and 58" can be translated to:

93 = g + 58

To find the value of g, it is necessary to isolate g first. To do this, we subtract both sides of the equation by 58:

93 - 58 = g + 58 - 58
93 - 58 = g

Simplifying:
g = 35

If the original cost of a TV is 1250.00 but decreases by 4.5% each week, how many weeks before the TV will cost 800.00?
NeX [460]
This is exponential growth/decay type problem...

F=Ir^t, F=final value, I=initial value, r=rate, t=time, in this case I=1250 and r=(1-.045)=0.955 so

F=1250(.955)^t  and we want to find t for when F=800 

800=1250(.955)^t

.64=.955^t  take the natural log of both sides...

ln.64=t ln.955

t=(ln.64)/ln.995

t≈9.69 weeks

t≈9.69 weeks (to nearest hundredth of a week)
