Answer:
The 11th term is 3072.
Step-by-step explanation:
First, find the common ratio and the first term. The common ratio is 6/3 or 2. The first term is 3.
Use the direct formula, xi=a*r^i-1, to find the eleventh term. a is first term, and i is the index or the number of the term.
Substitute: x11=3*2^(11-1)
Or x11=3*2^10
So x11 is 3072
Answer:
5) c. 6 pi cm
6) A. 81 pi mm^2
Step-by-step explanation:
5) Circumference of a circle = pi d
d = 6 cm
so
C = 6 pi cm
Answer
c. 6 pi cm
6)
A = pi r^2
r = d/2 = 18/2 = 9
so
A = pi 9^2
A = 81 pi mm^2
Answer
A. 81 pi mm^2
Answer:
D
Step-by-step explanation:
Proportional relationships come in the form
and 
is the constant of proportionality. By comparing the general case and your specific case 
, you can see that in your case 
.
4h+3=3.5h+6
0.5h+3=6
0.5h=3
h=6
Final answer: 6 hrs
