Answer:

Sales of trench coats increased 8.3 percentage points faster than total coat sales.

Step-by-step explanation:

<u>2006:</u>

top coats is 297,

parkas is 210,

jackets is 213,

raincoats is 137,

trench coats is 103

Total: 297+210+213+137+103=960

<u>2007:</u>

topcoats is 223,

parkas is 210,

jackets is 285,

raincoats is 259,

trench coats is 127

Total: 223+210+285+259+127=1,104

<u>Percent increase in total sales:</u>

\dfrac{1,104-960}{960}\cdot 100\%=15\%

<u>Percent increase in sales of trench coats:</u>

\dfrac{127-103}{103}\cdot 100\%\approx 23.3\%

Since 23.3\%-15\%=8.3\%, sales of trench coats increased 8.3 percentage points faster than total coat sales.

For each month of a given year except December, a worker earned the same monthly salary and donated one-tenth of that salary to
kiruha [24]

Answer:

D) 11/3

Step-by-step explanation:

Let x represent monthly salary.

We have been given that for each month of a given year except December, a worker earned the same monthly salary and donated one-tenth of that salary to charity.        

Salary earned in 11 months would be 11x.

Money donated in 11 months would be \frac{11x}{10}.

Further we are told that in December, the worker earned N times his usual monthly salary and donated one-fifth of his earnings to charity.

Salary for December would be Nx.

Money donated in December would be \frac{Nx}{5}.  

The worker's charitable contributions totaled one-eighth of his earnings for the entire year that is \frac{1}{8}\cdot (11x+Nx).

\frac{11x}{10}+\frac{Nx}{5}=\frac{1}{8}\cdot (11x+Nx)

Dividing whole equation by x, we will get:

\frac{11x}{10x}+\frac{Nx}{5x}=\frac{1}{8x}\cdot x(11+N)                

\frac{11}{10}+\frac{N}{5}=\frac{1}{8}\cdot (11+N)

\frac{11}{10}+\frac{N}{5}=\frac{11}{8}+\frac{N}{8}

Combine like terms:

\frac{N}{5}-\frac{N}{8}=\frac{11}{8}-\frac{11}{10}

\frac{N}{5}*40-\frac{N}{8}*40=\frac{11}{8}*40-\frac{11}{10}*40

8N-5N=11*5-11*4

3N=55-44

3N=11

\frac{3N}{3}=\frac{11}{3}\\\\N=\frac{11}{3}

Therefore, the value of N is 11/3 and option D is the correct choice.

A stick of butter in the shape of a rectangular prism has a length of 8 inches, a width of 3 inches, and a height of 3 inches. W
SVEN [57.7K]

Answer:

72in^3

Step-by-step explanation:

the information we know about the shape of the stick of butter:  

length = 8in

width = 3in

height=3in

The formula for the volume of a rectangular prism is:

volume=length*width*height

we find the volume by multiplying ll the measurements of the stick.

So we substitute the values to find the volume and we get the following:

volume=8in*3in*3in\\volume=72in^3

the volume of the stick of butter is 72in^3
