Sections of prefabricated fencing are each 4 1/3 feet long. how long are 6 1/2 sections placed end to end

zalisa [80]

we know that

$4\frac{1}{3}= \frac{(4*3+1)}{3} =\frac{13}{3}$

$6\frac{1}{2}= \frac{(6*2+1)}{2}=\frac{13}{2}$

To find how long are $6\frac{1}{2}$ sections placed end to end

Multiply the number of sections by the length of one section

so

$\frac{13}{2} *\frac{13}{3} =\frac{169}{6}\ ft$

$\frac{169}{6}\ ft =28\frac{1}{6}\ ft$

therefore

<u>the answer is</u>

$28\frac{1}{6} \ ft$

Determine the first four terms of the sequence in which the nth term is

Licemer1 [7]

<u>Answer:</u>

The correct answer option is: $\frac{1}{3} ,\frac{1}{4} ,\frac{1}{5} ,\frac{1}{6}$ .

<u>Step-by-step explanation:</u>

We know that the $nth$ term $a_n$ for an arithmetic sequence is given by:

$a_n=\frac{(n+1)!}{(n+2)!}$

where $n$ is the number of the position of the term.

We are supposed to find the first four terms of the sequence so we will substitute the values of $n$ from 1 to 4 in the given formula to get:

1st term:

$a_1=\frac{(1+1)!}{(1+2)!}=\frac{1}{3}$

2nd term:

$a_2=\frac{(2+1)!}{(2+2)!}=\frac{1}{4}$

3rd term:

$a_3=\frac{(3+1)!}{(3+2)!}=\frac{1}{5}$

4th term:

$a_4=\frac{(4+1)!}{(4+2)!}=\frac{1}{6}$

Help please & fast!! Due Tonight at 11:30 Aubrey is saving up to buy a new jacket. She already has $85 and can save an addit

padilas [110]

Hey there! I'm happy to help!

We'll call our weeks w and call our total savings s.

We have an initial $85 and then we add 7 every week. This means that we will be adding 7 for every week, so we will put this in our equation as 7w.

Therefore, our equation would be s=7w+85

Now, we plug in 8 for our w value to see how much money she will have after 8 weeks.

s=7(8)+85

s=56+85

s=141

Therefore, Aubrey will have saved $141 after 8 weeks.

I hope that this helps! Have a wonderful day! :D
