Answer:
132
Step-by-step explanation:
50 % means half
so 66 is half of whatever x is.
to find x you have to multiply 66 by 2 or add 66 to 66 which will give you 132 either way.

Your sequence
-8, 16/3, -32/9, 64/27
is a geometric sequence with first term -8 and common ratio
(16/3)/(-8) = (-32/9)/(16/3) = -2/3
The general term an of a geometric sequence with first term a1 and ratio r is given by
an = a1·r^(n-1)
For your sequence, this is
an = -8·(-2/3)^(n-1)
Divide total km by the km in the scale:
112 / 16 = 7
The answer is A. 7 cm
To find the 7th term, all you have to do is plug it in the equation.
First n would equal 7 because we are looking for the 7th term.
Now, let's plug everything we know into the equation.
a7 = 2+5 * (7-1)
= 2 + 5 * 6
= 2 + 30
= 32
In conclusion, the 7th term would equal 32.
Answer:
c = -20
Step-by-step explanation:
-21=1/2c-11
-21+11=1/2c
-10=1/2c
-10*2=c
-20=c
