Answer: I can help with number 10, and that answer is 105*
Step-by-step explanation: 10's x is paralell to the known angle, so the answer for x is equal to the known angle.
RQ × RP = RS × RT
9 × ( 9 + 13 ) = 11 × RT
9 × 22 = 11 × RT
Divide sides by 11
9 × 22 / 11 = 11 × RT / 11
Simplification
9 × 2 = RT
RT = 18
The formula you use is
V = (4/3)*pi*r^3
In this case, r = 6 is the radius, so the volume V is
V = (4/3)*pi*r^3
V = (4/3)*pi*6^3
V = (4/3)*pi*216
V = (4/3)*216*pi
V = 288pi
Answer: Upper Right-hand Choice
Hello,
2/10,-6/100,18/1000,-54/10000,162/100000;...
a(n+1)/a(n)=-3/10
a(0)=2/10*1
a(n)=2/10* (-3/10)^(n-1)
Answer B
