Answer:
C
Step-by-step explanation:
According to basic exponential rules, whenever we divide a two same variables, we subtract their powers so
would equal
=> 
4t+6s=4524
t+s=925
Multiply the second equation by -4 to cancel the variable t
4t+6s=4524
-4t-4s=-3700
2s = 824
Divide both sides by 2
S= 412
925-412= 513
T=513
What you would do is just divide 473 by 11

14.14 inches
Convert 135° into radians. 135*2pi/360=3pi/4.
6*3pi/4=18pi/4=9pi/2=14.14
Another viable method is to do 2pi*6*135/360=14.14
The answer is C because if you multiply 4 and 2 by 2 it would become 8 and 4, 8+4=12
