insens350 [35]
The correct answer to the following questions is this:

<span>Abbys school has a track it takes eight laps around the track to run 1 mile. 
This means that you have to run 8 laps in order to complete a 1 mile. 
1 lap = 1/8 mile

A. What fraction of a mile is two laps around the track? Show your work or explain how you know
Since 1 lap = 1/8 mile, then 2 laps would be 2/8 mile or 1/4 mile.

Abby ran 3 1/8 miles on Monday and 1 3/8 miles on Tuesday.
B. What was the total number of miles every right on Monday and Tuesday? show your work or explain how you know
On Monday, she ran 3 1/8 miles, 1 3/8 miles on Tuesday. The total number of miles is 3 1/8 + 1 3/8 = (3+1) (1/8 + 3/8) = 4 4/8 = 4 1/2 miles.

C. How many total lasted gym run on Monday and Tuesday? Show your work or explain how you know
This seems not clear regarding the gym.

Which formula can be used to find the nth term of a geometric sequence where the fifth term is 1/6 and the common ratio is 1/4?
OlgaM077 [116]

Answer:

a_n = 16(\frac{1}{4})^{n - 1}

Step-by-step explanation:

Given:

Fifth term of a geometric sequence = \frac{1}{16}

Common ratio (r) = ¼

Required:

Formula for the nth term of the geometric sequence

Solution:

Step 1: find the first term of the sequence

Formula for nth term of a geometric sequence = ar^{n - 1}, where:

a = first term

r = common ratio = ¼

Thus, we are given the 5th term to be ¹/16, so n here = 5.

Input all these values into the formula to find a, the first term.

\frac{1}{16} = a*\frac{1}{4}^{5 - 1}

\frac{1}{16} = a*\frac{1}{4}^{4}

\frac{1}{16} = a*\frac{1}{256}

\frac{1}{16} = \frac{a}{256}

Cross multiply

1*256 = a*16

Divide both sides by 16

\frac{256}{16} = \frac{16a}{16}

16 = a

a = 16

Step 2: input the value of a and r to find the nth term formula of the sequence

nth term = ar^{n - 1}

nth term = 16*\frac{1}{4}^{n - 1}

a_n = 16(\frac{1}{4})^{n - 1}
