squares of side x are cut from each corner of an 8 inches x 5 inch in rectangle, so that its sides can be folded to make a box with no top. define a function in terms of x that can represent the area of the base of the box

Answers

Answer 1

Answer:

When we do not have anything cut of the rectangle, the area is:

8in*5in = 40in^2.

Now, when we cut squares of length x in the corners, the measures of the base will be:

8in - 2*x

5in - 2*x

We subtract two times x in each case because we cut the squares in the four corners. (below you can see a drawing of this situation, where the doted rectangle is the area that we want to calculate)

Then the area as a function of x is:

A = (8in - 2*x)(5in - 2*x) = 40in^2  + 4*x^2 - 26*x

Maya bought a dozen specialty donuts at the bakery for $18. She purchased a mixture of frosted donuts for $2 each, glazed donuts for $1 each, and custard filled donuts for $5 each. If Maya purchased twice as many frosted donuts as custard filled donuts, how many of each type of donut did she buy? Variables: mixture of frosted donuts X y = glazed donuts Z = custard filled donuts System: System in standard form:​

Answers

Answer:

The quantity of frosted donuts = 2

The quantity of glazed donuts = 9

The quantity of custard filled donuts = 1

Step-by-step explanation:

Let the quantity of frosted donuts = [tex]x[/tex]

Let the quantity of glazed donuts = [tex]y[/tex]

Let the quantity of custard filled donuts = [tex]z[/tex]

As per question statements, following equations can be made:

What is the value of x

Answers

Answer:  The correct answer is: [A]:

__________________________________________________

      " Look at the graph of the relationship.  Find the y-value of the point that corresponds to x = 1 .   That value is the unit rate. "

__________________________________________________

Step-by-step explanation:

__________________________________________________

Note that the "unit rate" is the term that refers to:

a "quantity" / or "quantitative value" ;  

      →  of some type of "countable units"

{e.g. "currency"  — [such as:  dollars, cents,  pounds] ; "distance/length/ width/ height" — [such as:  miles, kilometers, meters, centimeters, yards, feet, inches] ;  pieces of fruits — [such as:  number of apples;  cans of soda, number of red dresses] ;  

__________________________________________________

per "single unit" of something — {e.g. per hour; per minute; per mile; per ounce; per hour; per dollar, per kilometer, per day, per week.

  {e.g.

            →    " 3 apples eaten  per [single] apricot eaten" ;

            →  " 46 miles per hour.

            →   " 8.3 cents per oz."  ;

            →  " 5 Liters of soda per dollar " ;

            →   " 2.3 grams per mole " ;

            →  " 4.6 mg solute / kg of solvent " ;  

            →  " 5 km / hr " ;  {that is:  " 5 km per hr " } .

            →  " 3 yds. per [single] square inch."

            →  " 35 parts per hundred" ; {that is:  " 35 percent" ; or: " 35 % " . } .

            →    " ... The cilantro is on sale for 33 cents per bundle ...} ."

  →  ... to provide a few examples.  

__________________________________________________

    On on Cartesian plane graph,  the  "x-axis" is located on the "horizontal axis" that represents the "independent variable" (or, at times, the "experimental value" — which can be manipulated — or "controlled" —or  be subjected to being "manipulated" / "controlled" / or, "selected".

  The "y-axis" is located on the "vertical axis" that represents the "dependent variable" (or, at times, the "control value") that cannot be "manipulated" / controlled/ or "selected" / since it represents the "y-value" of the corresponding coordinate to which the "x-value" happens to corresponds to at the given value for "x" .

  So, if the "unit rate" represents the "single unit rate" ;  we look at "x = 1 " ;  since we are "choosing" this particular "single" rate of per "single" (i.e. "1" ) ; so we do not have a choice in what "y-value" of the particular graph to select.  We can control the fact that we are "choosing" to find the "unit" rate, so we select the "independent variable" , "x = 1 " . We then examine the "corresponding y-value" that happens to exist when "x = 1 " .

{Note that we have "no control" over what that "y-value" is ; at the: "[point which:  " x = 1 .] . "

_________________________________________________  

→  As such, that "y-value" [insert that numeric "y-value" ;                        followed by the units represented by the "y-axis" ] ;

           per  " 1 " [insert "single unit" represented by the "x-axis" ] ;

_________________________________________________    

          →   is the:  "unit rate" .

__________________________________________________

So:  

   The correct answer is:    [A]:  

__________________________________________________

    " Look at the graph of the relationship.  Find the y-value of the point that corresponds to x = 1 .   That value is the unit rate. "

Marlina received her salary on Friday. She spent one-half of her salary on rent and then spent $338 on her electric and water bill. Next, she spent one-half of what was left on her phone bill. After spending $56.00 on gas for her car, Marlina had $102.00 left. How much did Marlin spend on rent?

Answers

Answer:

Marlina spent $654 on rent.

Step-by-step explanation:

Let the amount of money Marlina's received for her salary be x.

We know that she spent one-half of her salary on rent and then $338 on her electric and water bill. Therefore, the amount of money she has left can be so far can be represented by:

[tex]\displaystyle x-\frac{1}{2}x-338[/tex]

Next, she spent one-half of what was left on her phone bill. So, we can subtract one-half of the above expression to what we have so far.

[tex]\displaystyle x-\frac{1}{2}x-338-\frac{1}{2}\left(x-\frac{1}{2}x-338\right)[/tex]

Finally, she spent $56 for gas. Thus, we will subtract 56:

[tex]\displaystyle x-\frac{1}{2}x-338-\frac{1}{2}\left(x-\frac{1}{2}x-338\right)-56[/tex]

And we know that after all of the expenses, she will have $102 left. Therefore:

[tex]\displaystyle x-\frac{1}{2}x-338-\frac{1}{2}\left(x-\frac{1}{2}x-338\right)-56=102[/tex]

We want to know how much Marlina spent on rent. So, we can find her salary, since we know the rent is one-half of the salary. To find the salary, we will solve for x.

Distribute:

[tex]\displaystyle x-\frac{1}{2}x-338-\frac{1}{2}x+\frac{1}{4}x+169-56=102[/tex]

Rearrange:

[tex]\displaystyle \left(x-\frac{1}{2}x-\frac{1}{2}x+\frac{1}{4}x\right)+(-338+169-56)=102[/tex]

Combine like terms:

[tex]\displaystyle \frac{1}{4}x-225=102[/tex]

Add 225 to both sides:

[tex]\displaystyle \frac{1}{4}x=327[/tex]

Multiply both sides by 4:

[tex]x=\$ 1308[/tex]

Therefore, Marlina received a total of $1308 for her salary.

We know that she spent half of her salary on rent. Therefore, the amount she spent on rent is:

[tex]\displaystyle r=\frac{1}{2}(1308)=\$ 654[/tex]

Marlina spent a total of $654 on rent.

9514 1404 393

Answer:

  $654

Step-by-step explanation:

Let r represent the amount of Marlina's rent. Since that is half her salary, the amount remaining after paying rent is also equal to r. The disposition of that remaining amount is ...

  $338 on electric and water (E&W)

  (1/2)(r -338) on phone . . . this is half of what is left after paying E&W

  $56 on gas

  $102 unaccounted

__

The total of these amounts is equal to r, so we have ...

  r = 338 + 1/2(r -338) +56 +102

  1/2r = 338 -169 +56 +102 = 327 . . . . . eliminate parentheses, subtract 1/2r

  r = 2(327) = 654 . . . . . multiply by 2 to get r by itself

Marlina spends $654 on rent.

the owner of an apple orchard ships apples in boxes that weigh 2 kilograms ( kg ) when empty. the average apple weighs 0.25 kg and the total weight of a box filled with apples is 12 kg. how many apples are packed in each box?

a. 14
b. 30
c. 40
d. 56

Answers

Given parameters:

Weight of box = 2kg

Average weight of an apple  = 0.25kg

Total weight of box filled with apples  = 12kg

Unknown:

Number of apples packed in each box = ?

Solution:

    Since 1 apple weighs 0,25kg, let us find the weight of the apples in the box

Box + apples  = 12kg

weight of box = 2kg

    Weight of apples  = 12kg - 2kg = 10kg

 So;

          0.25kg is the weight of 1 apple;

            10kg  of apples will equal     [tex]\frac{10}{0.25}[/tex]   = 40 apples

Therefore, 40 apples are packed in the box

A municipal bond service has three rating categories (A, B, and C). Suppose that in the past year, of the municipal bonds issued throughout the United States, 70% were rated A, 20% were rated B, and 10% were rated C. Of the municipal bonds rated A, 50% were issued by cities, 40% by suburbs, and 10% by rural areas. Of the municipal bonds issued B, 60% were issued by cities, 20% by suburbs, and 20% by rural areas. Of the municipal bonds rated C, 90% were issued by cities, 5% by suburbs, and 5% by rural areas. a. If a new municipal bond is to be issued by a city, what is the probability that it will receive an A rating? b. What proportion of municipal bonds are issued by cities? c. What proportion of municipal bonds are issued by suburbs?

Answers

Answer:

(a) The probability that the new municipal bond issued will receive an A rating given that it was issued by a city is 0.196.

(b) Thus, the probability of municipal bonds issued by suburbs is 0.325.

Step-by-step explanation:

The data provided is as follows:

P (A) = 0.70

P (B) = 0.20

P (C) = 0.10

P (c | A) = 0.50

P (s | A) = 0.40

P (r | A) = 0.10

P (c | B) = 0.60

P (s | B) = 0.20

P (r | B) = 0.20

P (c | C) = 0.90

P (s | C) = 0.05

P (r | C) = 0.05

(a)

The Bayes' theorem states that the conditional probability of an event Y[tex]_{i}[/tex] given that another event X has already occurred is:

[tex]P(Y|X)=\frac{P(X|Y)P(Y)}{\sum\limits_{i} {P(X|Y_{i})P(Y_{i})}}[/tex]

Compute the probability that the new municipal bond issued will receive an A rating given that it was issued by a city as follows:

[tex]P(A|c)=\frac{P(c|A)P(A)}{P(c|A)P(A)+P(c|B)P(B)+P(c|C)P(C)}[/tex]

           [tex]=\frac{(0.50\times 0.70)}{(0.50\times 0.70)+(0.60\times 0.20)+(0.10\times 0.90)}\\\\=\frac{0.35}{0.56}\\\\=0.196[/tex]

Thus, the probability that the new municipal bond issued will receive an A rating given that it was issued by a city is 0.196.

(b)

The law of total probability states that:

[tex]P(X)=\sum\limits_{i} {P(X|Y_{i})}[/tex]

Compute the probability of municipal bonds issued by suburbs as follows:

[tex]P(s)=P(s|A)P(A)+P(s|B)P(B)+P(s|C)P(C)[/tex]

        [tex]=(0.40\times 0.70)+(0.20\times 0.20)+(0.10\times 0.05)\\\\=0.28+0.04+0.005\\\\=0.325[/tex]

Thus, the probability of municipal bonds issued by suburbs is 0.325.
