What is the COMMON RATIO of the geometric sequence: 3024, 504, 84, 14, ...* 2

Mathematics

Anton [14]3 years ago

Answer:

\frac{1}{6}

Step-by-step explanation:

To find the common ratio of a geometric sequence, we  can divide one of the terms by the one before it

r = \frac{u_n}{u_{n-1}}

Let's try to apply that to the sequence in the question prompt:

r = \frac{504}{3024}\\\\r = \frac{1}{6}

The common ratio must be the same all throughout the sequence, so we can try this with two other values from the sequence just to be sure

r = \frac{84}{504}\\\\r = \frac{1}{6}

Now we can be sure that the common ratio of this geometric sequence is \frac{1}{6}

Note: r is usually used to denote the common ratio

Good luck!

Please help me Arithmetic Reasoning
jek_recluse [69]

Step-by-step explanation:

Price of Jeans = $78.35

30% coupon = 30% × $78.35 = $23.51

6% sales tax = 6% × $78.35 = $4.70

1% local option tax = 1% × $78.35 = $0.78

Total cost of jeans = $78.35 - $23.51 + $4.70 + $0.78 = $60.32

After spending some time looking for his pump, Marlon pumps up an uninflated balloon, pumping air into it at a constant rate. He
galina1969 [7]

Answer:

Graph D

Step-by-step explanation:

Initially, Marlon was looking for his pump. Thus, no air was pumped into the balloon until he got the pump. On getting the pump, he inflated the balloon with air at a constant rate, after which he tied it with a string to prevent the air from escaping.

The analysis is that, at the time he decided to inflate the balloon till he got a pump, the volume of air in the balloon is zero with respect to time. Pumping air at a steady rate into the balloon increases the volume of air flowing into it gradually and steadily.

When the volume got to a definite amount, he stopped pumping air and tied with a string. Thus, the volume of air in the balloon remains constant.

Step-by-step explanation:

Plug in the values into the equation and compute. 5*6 - 20 = 10, 5*10 - 20 = 30, 5*20 - 20 = 80.
