mr. eaton is ordering sandwiches for a school picnic. the best deal is the 6-foot-long sandwich, which is cut into 4-inch-long pieces. mr. eaton expects 90 people to attend the picnic. he thinks each person will eat 2 pieces. how many 6-foot-long sandwiches should he order?

Answers

He should order 10 sandwiches of 6 foot long so, as to make sure that everyone will eat 2 pieces.

What is Conversion ?

We need to convert between the units in order to ensure the accuracy and to prevent measurement misinterpretation. For example, we do not measure the pencil's length in kilometres. In this situation, one must convert from kilometres (km) to centimetres (cm) (cm). In most cases, multiplicative conversion factors are used to convert one unit to another of the same quantity. Let's see how to change the length and mass units.

1 Feet = 12 Inches

So, 6 Foot = 72 inches

The Length of sandwich- piece is 4 inch

So, when we convert 6 foot long sandwich into 4 inch,

Then we get number of piece is = 72/4 = 18

From 6 foot long sandwich we get 18 pieces of 4 inch long sub.

Now, Total people who will attend picnic is 40

and each people will eat 2 pieces.

It means total number of piece required = 2 (90) = 180

Mr. eaton required 180 pieces of sandwiches.

Number of sandwiches = 180 / 1.8 = 10

He should order 10 sandwiches of 6 foot long.

A company produce two type of olar panel per​ year: x thouand of type A and y thouand of type B. The revenue and cot​ equation, in million of​ dollar, for the year are given a follow. ​R(x,y)=4x5y ​C(x,y)=x^2-3xy7y^23x-22y-4 Determine how many of each type of olar panel hould be produced per year to maximize profit

Answers

Using partial derivatives, we know that in order to optimize profit, the company should produce 7,000 type A solar panels and 8,000 type B solar panels annually.

What are partial derivatives?

A function of two or more variables can yield partial derivatives.

Writing the derivative with regard to x while treating all other variables as constants allows one to determine the partial derivative of a function with respect to one variable, let's say x.

The partial derivatives for each of the other

So, for a business making two different types of solar panels, the revenue and cost functions are provided by:

[tex]\begin{aligned}&R(x, y)=4 x+2 y \\&C(x, y)=x^2-4 x y+9 y^2+22 x-114 y-5\end{aligned}[/tex]

If revenue and cost are stated in millions of dollars annually, x represents the thousands of type A solar panels produced and sold annually, and y represents the thousands of type B solar panels produced and sold annually.

By deducting costs from revenues, the profit function is obtained as follows:

[tex]\begin{aligned}&P(x, y)=R(x, y)-C(x, y) \\&P(x, y)=4 x+2 y-\left(x^2-4 x y+9 y^2+22 x-114 y-5\right) \\&P(x, y)=-x^2-9 y^2-18 x+116 y+4 x y+5\end{aligned}[/tex]

The profit function's partial derivatives with regard to x and y are as follows:

[tex]\begin{aligned}&\frac{\partial P}{\partial x}=-2 x+4 y-18 \\&\frac{\partial P}{\partial y}=4 x-18 y+116\end{aligned}[/tex]

When both of these partial derivatives are equal to zero, the profit is maximized:

[tex]\begin{aligned}&0=-2 x+4 y-18 \\&0=4 x-18 y+116\end{aligned}[/tex]

The first equation above is multiplied by two, and the two equations are then added to yield:

[tex]\begin{aligned}&0=-10 y+80 \\&y=8\end{aligned}[/tex]

Inputting into the first equation results in:

[tex]\begin{aligned}&0=-2 x+4(8)-18 \\&2 x=14 \\&x=7\end{aligned}[/tex]

Therefore, using partial derivatives, we know that in order to optimize profit, the company should produce 7,000 type A solar panels and 8,000 type B solar panels annually.

find the open intervals on which the function ​f(x)axbx​c, a​0, is increasing and decreasing. describe the reasoning behind your answer.

Answers

The intervals on which the function f(x) = ax² + bx + c (where "a" doesn't = 0) is increasing and decreasing is x>-b/2a and x<-b/2a

Given that,

We have to find the intervals on which the function f(x) = ax² + bx + c (where "a" doesn't = 0) is increasing and decreasing.

We know that,

Take the function equation,

f(x)=ax² + bx + c

The derivative of the function of x is  

f'(x)=ax+b

So, f(x) is increasing when f'(x) > 0

f(x) is decreasing when f'(x) < 0

Then we can say

f'(x) > 0 , when  b > 0  and a < 0

2ax + b < 0

2ax < - b

x<-b/2a

Now,

f'(x) < 0 , when  b < 0  and a > 0

2ax + b > 0

2ax > - b

x>-b/2a

Therefore, the intervals on which the function f(x) = ax² + bx + c (where "a" doesn't = 0) is increasing and decreasing is x>-b/2a and x<-b/2a.

a) The expected return for stocks a and b is 13.56% and 20.02% respectively.

b) The standard deviation for stocks a and b are 8.32% and 32.60%.

a) Expected return = Probability of recession × Return during recession + Probability of normal × Return during normal + Probability of boom × Return during boom

Expected return for stock A = 0.21 × 0.04 + 0.61 × 0.12 + 0.18 × 0.30

The expected return for stock A = 0.1356

The expected return for stock A = 13.56%

Expected return for stock B = 0.21 × (-0.41) + 0.61 × 0.31 + 0.18 × 0.54

The expected return for stock B = 0.2002

The tank is to be made by welding thin stainless steel plates together along their edges. As the production engineer, your job is to find dimensions for the base and height that will make the tank weight as little as possible.

Answers

For dimensions of x =10 and y=5 for the base and height that will make the tank weight as little as possible.

Here we are given the information of a square-based, open-top, rectangular steel holding tank, so here the tank is in the shape of a cuboid and we know  the formula  for :

volume = x*y*z, as  here it is a square base, so the volume will be

volume =  x²*y, where x and y are the dimension of the base and height

So for the  given reason,  

=>x²*y =  500

=> y = 500/x²

Again, the surface area formula  will be

S=x²+4xy, substituting the value of  y in this question

=>S=x²+4x(500/x²)

=>S=x²+2000/x

Differentiating the above formula with respect to x, we get

=>2x-2000/x²=0

=>2x³= 2000

=>x³= 1000

=>x =10

so the substituting the x values of x in  the equation y , we get

y = 500/x²

=>y = 5

so the dimensions are x= 10 and y=5

The student first prepares a saturated solution of sodium hydroxide using freshly distilled or deionized water. She measures about 5 mL with a graduated cylinder and dilutes to 1 L in a plastic bottle with freshly distilled or deionized water to make a solution that is about 0.1 M. To determine the exact concentration she puts the NaOH solution in a buret and titrates a carefully-weighed pre-dried solid acid of known molar mass. She records the volume of NaOH needed to neutralize it and repeats the process several times to determine the concentration of the NaOH solution. She calculates the concentration and uncertainty in the concentration of the NaOH from the titration data. Why can\'t the student just weigh the sodium hydroxide directly to make a standard? Select all that apply. NaOH pellets react with water. NaOH pellets react with oxygen. NaOH pellets react with hydrogen. NaOH pellets react with carbon dioxide. NaOH pellets react with nitrogen. Why did the student first prepare a saturated solution? A. Saturated solutions are higher in purity than unsaturated solutions. B. Unsaturated NaOH solutions are light-sensitive. C. She can calculate the concentration of the saturated NaOH solution from the Ksp of NaOH. D. Any sodium hydrogen carbonate formed by the reaction of NaOH with atmospheric carbon dioxide will precipitate in the saturated solution. The student prepares the NaOH solution of high purity but unknown concentration by taking about 5 mL of the supernatant at the top of the saturated solution adding it to a plastic bottle with about 1 L of freshly distilled or deionized water. The bottom of the solution contains some white solids which are likely to be (select all correct answers): sodium hydroxide sodium hydrogen sulfate sodium silicate CO2(s) H2O(s) phthalic acid sodium hydrogen carbonate Why is a plastic bottle is generally preferred to glass bottle during the above step? A. The reaction between sodium hydroxide and plastic produces plastic hydroxide. B. Sodium hydroxide renders plastic inert by a process called passivation. C. Sodium hydroxide reacts slowly with glass, forming sodium silicate. D. Sodium hydroxide reacts with polyethylene. The concentration of saturated NaOH is 50.0% w/w and the density is 1.52 g/mL. If exactly 4.00 mL were diluted to 1.000 L, what would be the concentration? Why is potassium acid phthalate (KHC8H4O4, MM = 204.227 g/mol) so widely used as a standard in acid-base titrations? Select all that apply. It is stable to air It is expensive It is easy to dry It has a slowly changing pH at the equivalence point It has a relatively high molar mass It is available in high purity A student dries the pure potassium acid phthalate (KHC8H4O4) in the oven overnight to A. remove water B. purify the matrix C. remove carbon dioxide adn sulfer dioxide D. anneal the crystal structure She weighs 0.1553 g of dry potassium acid phthalate into a flask and adds some water from a graduated cylinder to dissolve it. Why doesn\'t she measure the volume of water with a more accurate device? A. The accuracy of the graduated cylinder is sufficient to measure to two decimal places which is all the precision needed for a titration. B. It would be better to measure the mass because it can be read to four decimal places with an analytical balance. C. The quantity of water actually is important and should be measured accurately because it affects the starting concentration thus the starting pH of the solution. D. The volume of water added is not important because the titration equivalence point depends only on the number of millimoles of potassium acid phthalate and not its concentration. The titration of 0.1553 g of dry potassium acid phthalate (MM = 204.227 g/mol) requires 49.84 mL of NaOH solution. What is the concentration of the NaOH solution? Why is freshly distilled or deionized water used in this standardization? A. Freashly distilled water contains no hydrogen peroxide B. Distilles water contains calcium, which stabilizes the sodium hydroxide C. Freashly deionized water has a pH of 4.72 D. There is little CO2 in freshly deionized or distilled water Which is a characteristic of a person with high self-esteem? a wide circle of friends feels worthy of love high academic achievement no drug or alcohol use According to the introduction, Mary Shelley wanted to write what type ofghost story?A.
