9. If one box of books contains 7.5% of the total shipment and each box includes 15 books, how many books are included in the to

Inga [223]

Answer:

210 books

Step-by-step explanation:

Hello

I think I can help you with this

Step 1

if one box is 7.5% of the total shipment, how many box is the total shipment

1 box =7.5%

x?box=100%

using a rule of three

$\frac{1\ box}{7.5 } =\frac{x}{100}$

Now, isolating x

$\frac{1\ box*100}{7.5 } =x\\x=13.34\ boxes$

13.34 boxes is the total

Step 2

find the total of books

we will need 14 boxes, because it does not exist 0.34 box

so, the total of books=

number of boxes*number of books included in each box

=14 boxes*15 books

=210 books

Have a great day

Answer:

I would go with letter F because it's most reasonable.

Step-by-step explanation:

Each row has 4 squares.

Since three are circled it is 3/4.

So 3/4 divided by 4 is 3/16.

Find the first 4 terms of the Arithmetic sequence. f(n) = f(n-1) + 5 f(1) = -2

nexus9112 [7]

f(n) = f(n-1) + 5 simply means

the next term or f(n), will have a value of
the one before it, or f(n-1), +5

so.. you're looking for the 4th term, that means f(4)
to get 4th term then, that will be the 3rd term plus 5,
whatever the 3rd term is

now... f(1) = -2, simply means, the term 1, or f(1), or first term, is -2

now to find a term value in an arithmetic sequence $\bf f(n)=f(1)+(n-1)d\\\\
\begin{cases}
n=n^{th}\ term\to &4\\
f(1)=\textit{first term}\to &-2\\
d=
\begin{array}{llll}
\textit{common difference, or amount}\\
\textit{added to get the next term}
\end{array}\to &5
\end{cases}\\\\
-----------------------------\\\\
thus
\\\\
f(4)=f(1)+(4-1)5$

and I'm sure you know what f(1) is, so, just plug it in, to get f(4), or 4th term
