Answer:
Step-by-step explanation:
common ratio=18/-3=-108/18=-6, a=-3
sn=a(r^n-1)(r-1)
sn=-3((-6)^n-1)(-6-1)
sn=-3(-6)^8-1)/(-7)
s8=-3(1679615)/(-7)
s8=719836
Answer:
3.6 pounds
Step-by-step explanation:
If 1 bottle weighs 3/5 pounds
the 6 bottles will weigh 6 x 3/5
= 18/5
ratio method :
1:3/5
6:x
since the ratios are direct we can cross multiply
18/5 = 1x
so the 6 bottles weigh 18/5 pounds or 3.6 pounds
Each position in the sequence has 3 choices, and there are 5 positions, so we multiply 3 by itself 5 times:
Answer:
D. $8 per hour

The rate of pay is found by dividing the pay by the number of hours it is for.
$40/(5 h) = $8/h
The worker gets paid $8 per hour.
Upper Left for certain.
Lower right. You can check it out using
a^2 + b^2 = c^2
14^2 + 48^2 = 50^2
196 + 2304 =? 2500
2500 = 2500 This checks out to being true. I don't think there are any others.
