Answer:

45 %

Step-by-step explanation:

decreasing by half would be 50 percent making it only 20 dollars. In this situation it is 2 dollars more. 45 percent of 40 is 18. subtract: 40-18=22

The decreased percent of the cost of the lamp is 45%.

A percentage is expressed as a number or ratio that can be expressed as fraction of 100. It is denoted by % symbol.

The cost of a lamp was reduced from $40 to $22.

Initial price = $40

Final price= $22

Decreased percentage =[tex]\frac{initial price-final price}{initial price} *100[/tex]

                                       =[tex]\frac{40-22}{40} *100[/tex]

                                       = 45%

Hence, the decreased percent of the cost of the lamp is 45%.

Answer:

Dimensions are 2 and 4

Step-by-step explanation:

Area= a*b=8

Perimeter=2(a+b)=12 => a+b = 12/2. a+b = 6

a+b=6 =>a=6-b

If a=2=>b=4 so 4+2=6 , 4*2=8 and 4*2+2*2=12

If a=4=>b=2 so 4+2=6 , 4*2=8 and 4*2+2*2=12

Dimensions are 2 and 4

The possible dimensions of the table are -

L = 2, B = 4.

or

L = 4, B = 2.

Given is a rectangular table top has an area of 8 ft and a perimeter of 12 ft.

Let the dimensions of the rectangular table be {x} ft and {y} ft respectively.

We can write -

xy = 8                               ....... Eq(1)

2(x + y) = 12

x + y = 6                                 ....... Eq(2)

y = (6 - x)

Then, we can write -

x(6 - x) = 8

- x² + 6x = 8

x² - 6x + 8 = 0

(x - 2)(x - 4) = 0

We get -

x = 2 and x = 4

Now,

For x = 2, y = 4.

For x = 4, y = 2.

Therefore, the possible dimensions of the table are -

L = 2, B = 4.

or

L = 4, B = 2.

Step-by-step explanation:

Based on the number of weeks that Lorena's baby brother has aged, in hours, the baby is 3,864 hours.

Lorena's baby brother is 23 weeks old.

First find out the number of hours in a week:

= Number of hours in day x number of days in week

= 24 x 7

= 168 hours

In 23 weeks, the baby brother would be:

= 168 x 23 weeks

= 3,864 hours

In conclusion, her brother is 3,864 hours old.

Answer:

seventy-three

Step-by-step explanation:

Let's use the point-slope formula to write the equation of this line.

The point-slope formula is y - y₁ = m(x - x₁).

In the formula, x₁ and y₁ are points and the m is our slope

Now let's substitute.

y + 2 = -3/2(x - 6).

Notice that I put y + 2 above since y - (-2) means y + 2.

Now distribute the -3/2 through the parentheses.

This gives us -3/2x + 9.

Bring down your y + 2 and we have y + 2 = -3/2x + 9.

To put this in standard form, we need to multiply both

sides by 2 because we can't have any fractions.

This gives us 2y + 4 = -3x + 18.

Now move the +4 to the right by subtracting

4 from each side to get 2y = -3x + 14.

Now move your x term to the right by adding 3x to both sides.

So our final answer reads 3x + 2y = 14.

Answer:

672.7436 units of the sale item should the store stock in order to have at most a 1 percent chance of running short of the item on the day of the sale

Step-by-step explanation:

No. of customers pass the display on the day of sale = 1462

Proportion of people will purchase if pass such a special display = 0.43

Mean = E(X)=np

E(X)=[tex]1462 \times 0.43[/tex]

E(X)=628.66

Standard deviation = [tex]\sqrt{npq}[/tex]

Standard deviation =[tex]\sqrt{1462 \times 0.43 \times (1-0.43)}=18.92[/tex]

Now we are supposed to find how many units of the sale item should the store stock in order to have at most a 1 percent chance of running short of the item on the day of the sale

P(X<x)=0.01

Using z table

[tex]P(\frac{x-\mu}{\sigma})= 2.33 \\\frac{x-628.66}{18.92}=2.33\\x=(2.33 \times 18.92)+628.66\\x=672.7436[/tex]

Hence 672.7436 units of the sale item should the store stock in order to have at most a 1 percent chance of running short of the item on the day of the sale

The number of units should be 672.7436 units.

Since No. of customers pass the display on the day of sale is 1462 and the proportion of people who will purchase if pass such a special display is 0.43

So,

Mean should be = 43% of 1,462

= 628.66

Now the standard deviation should be

[tex]= \sqrt{1462 \times 0.43 \times (1-0.43)}[/tex]

= 18.92

Now the number of units should be

[tex]x - 628.66 \div 18.92 = 2.33[/tex]

x = 672.7436

Answer:

They would produce 14,400 packages of zetsy and the regular profit making would be $11,340.

Step-by-step explanation:

12-ounce

regular = 65%

mild = 35%

extra sharp zesty blend = 75%

extra sharp mild = 25%

8,100 mild for = $1.30

3,500 extra sharp = $1.50

cost blend and package = $0.30

regular sold = $1.8

zesty = $2.10

first we calculate the cost of each product

conversion Of  ounces to pounds:

1 pound = 16 ounces

regular cost:

12/16 pounds x 65% mild x $1.30

= 0.63375

12/16 pounds x 35% sharp x $1.50

= 0.39375‬

+ blend and package $0.30

total = $1.3275‬

contribution: $1.8 – $1.3275

= $0,4725‬

zesty cost:

12/16 pounds x 75% mild x $1.30

= 0.73125‬

12/16 pounds x 25% sharp x $1.50

= 0.28125‬

+ blend and package 0.30

total $1,3125‬

contribution: $2.10 – $1.3125

= $0,7875‬

to maximize profit:

profit = $0.4725Regular + $0.7875zetzy

adding the  constraint:

mild = Regular x $0.4775 + Zetzy x $0.5625 = 8,100

and

sharp = Regular x $0.2625 + Zetzy x $0.1875 = 3,100

contribution generated by each product/pound:

                                 Regular        Zesty

CM                          $ 0.47250 $ 0.47250

Constrain resource

( pounds of mild)         0.48750 0.56250

CM per constrain        $ 0.9692 $ 1.4000

Constrain resource

( pounds of sharp)         0.26250 0.18750

CM per constrain           $ 1.80      $ 4.20

As zesty is better we produce as much as we can:

8,100 pounts / 0.5625 per cheese spreads: 14,400

check for possibilities of other constraint:

14,400 zesty packages x 0.1875 pounds each = 2,700 pounds

because it’s possible we only produce zetsy

profit = $0.4725 (0) + $0.7875 (14,400)

profit =  $ 11,340
