Divide the total price by the total number of books from each printer to find the price per book:

Printer A: $350 / 100 books = $3.50 per book


Printer B: $150 / 40 books = $3.75


Printer A has the lowest price.

But, during the same summer, teachers stopped wearing high heels; each of them became 4% shorter. Copy and fill in the chart. Te
alexgriva [62]

Answer:

It is given that,

'When the teachers stopped wearing heels, they became 4% shorter'.

So, the relation becomes,

<em>Height without heels = Height with heels - 4% of height with heels</em>

Then, we have,

1. Ms. Mathey is 190 cm with heels.

So, Ms. Mathey = 190-4% of 190 = 190 - 7.6 = 182.4 cm  without heels

2. Mrs. Meansy is 162.5 cm with heels.        

So, Mrs. Meansy =  162.5-4% of 162.5  = 162.5 - 6.5 = 156 cm  without heels

3. Ms. Cool is 140 cm with heels.

So, Ms. Cool = 140-4% of 140 = 140 - 5.6 = 134.4 cm  without heels

Also, the relation can be written as,

<em>Height with heels = Height without heels + 4% of height without heels</em>

4. Miss Short is 155.1 cm without heels

So, Miss Short = 155.1+4% of 155.1 = 155.1+6.2 = 161.3 cm with heels        

5. Miss Lora is 159.8 cm without heels

So, Miss Lora =  159.8+4% of 159.8  = 159.8+6.4 = 166.2 cm with heels

Thus, the final table is,

                          Height with Heels                Height without Heels

Ms. Mathey               190 cm                                       182.4 cm

Mrs. Meansy             162.5 cm                                    156 cm

Ms. Cool                   140 cm                                       134.4 cm

Miss Short                 161.3 cm                                      155.1 cm

Miss Lora                  166.2 cm                                     159.8 cm

Farmer Bill sold potatoes at the farm market. He sold a quarter to the first person, 4/9 of what was left to the second person,
mel-nik [20]

Answer: 120 lb of potatoes.

Step-by-step explanation:

Let the pounds of potatoes sold by farmer Bill      = X lb

Fractional part sold to the first person                    = 1/4

Therefore 1/4 of X                                                      = 1/4  x X

                                                                                    = X/4 lb of potatoes.

No of potatoes left for sale                                        = X - X/4

                                                                                    = ( 4x - x )/4

                                                                                    = 3x/4 lb.

Fractional part sold to the second person out of the reminder = 4/9

Therefore 4/9 of 3x/4                                                 = 4/9 x 3x/4

                                                                                    = x/3 lb of potatoes.

Amount of potatoes left for sale                               = 3x/4 - x/3

Resolve into fraction , we have                                 = (9x - 4x)/12, because 12 is the LCM.

                                                                                    = 5x/12

Third buyer bought 4/5 of the left over                    = 4/5 of 5x/12

                                                                                   =   x/3 lb of potatoes.

Amount  of potatoes left                                           =   5x/12 - x/3

Resolve in to fraction again  taking 12 as the LCM =   ( 5x - 4x )/12

                                                                                   = x/12 lb of potatoes .

Therefore, the left over was 10 lb .

To determine the value of x now which correspond to the amount of potatoes sold by Farmer Bill, we shall the equate the left to  x/12 = 10                                                                                                                

we now cross multiply to get the value of x                             x = 120 lb.

therefore the pound of potatoes sold by farmer Bill  = 120 lb.

What is the volume of the solid generated when the region in the first quadrant bounded by the graph of y=x^3, the x-axis, and t
son4ous [18]

Answer:

The first thing we need to do is to find the area bounded by:

y = x^3

y = 0

between:

x = 0 and x = 2

This is the integral of the given function between x = 0 and x = 2, written as:

\int\limits^2_0 {x^3} \, dx = \frac{2^4}{4}  - \frac{0^4}{4} = 2^2 = 4

This means that the area of the bounded region is 4 square units.

Now, if we do a full rotation around the x-axis, the volume generated will be equal to the area that we obtained times 2*pi units.

The volume is:

V = (4 square units)*(2*pi units) = 8*pi cubic units.

(Notice that no option coincides with this, there may be a mistake in the options)
