Answer:

1651

Step-by-step explanation:

let s say that the price before the increase is x

to apply an increase of 9% it does x + x*0.09 = x*(1+0.09)=x*1.09

and we know that this value is 1800

x*1.09=1800

<=>

x = 1800/1.09=1651.376147

to the nearest penny it gives 1651

laiz [17]

six pipes are laid end to end to form a row. Each pipe is 9 1/3 inches long. how long is the row of pipes, in feet?

Answer:

4.67 feet or 4 feet 8 inches or $4\frac{2}{3}$ feet

Step-by-step explanation:

Let x be the length of the row pipes.

Given:

Number of pipes = 6

Each pipe has length $9\frac{1}{3}$ inches. and six pipes are laid end to end to form a row.

The total length of the row is equal to length of the 6 pipes.

So, total length of row = Number of pipes $\times$ Length of the pipe

$x=\frac{28}{3}\times 6$

$x=28\times 2$

$x=56$ inches

convert inch into feet.

$x=\frac{56}{12}$

$x=4.67 feet$

Therefore, The length of the row is 4.67 feet or 4 feet 8 inches or $4\frac{2}{3}$ feet .
