answer which is equal to 7(3m-7n)

Answer:

The correct option will be:  C.  3

Step-by-step explanation:

The given table is..........

[tex]x :[/tex]      -6      -3      -1      0      1      4

[tex]f(x) :[/tex]  27     6      2      3      6     27

The formula for average rate of change is:   [tex]\frac{f(b)-f(a)}{b-a}[/tex] , where [tex][a,b][/tex] is the given interval.

Here the interval is [-3, 4]. So,  [tex]a=-3[/tex] and [tex]b=4[/tex]

Now, plugging the values of [tex]a[/tex] and [tex]b[/tex] into the above formula, we will get........

[tex]\frac{f(4)-f(-3)}{4-(-3)}[/tex]

From the given table, we will get  [tex]f(4)=27[/tex] and [tex]f(-3)=6[/tex]

So, the average rate of change will be:  [tex]\frac{27-6}{4-(-3)}= \frac{21}{7}=3[/tex]

Answer:

The person that answered it above me is correct

Step-by-step explanation:

a) The cost of goods available for sale is $16,800.

b) The calculated values for the cost of goods sold under the FIFO and LIFO methods match the values obtained using the formulas, proving their accuracy.

(a) Beginning Inventory:

100 units at $8 per unit = $800

Purchases:

Feb. 20:

600 units at $9 per unit

= $5,400

May 5: 500 units at $10 per unit

= $5,000

Aug. 12: 400 units at $11 per unit

= $4,400

Dec. 8: 100 units at $12 per unit

= $1,200

Total Cost of Goods Available for Sale

= $800 + $5,400 + $5,000 + $4,400 + $1,200

= $16,800

Therefore, the cost of goods is $16,800.

(b) Given the sales of 1,500 units,

FIFO (First-In, First-Out):

The ending inventory consists of the most recent purchases.

Ending Inventory (FIFO):

Dec. 8: 100 units at $12 per unit

= $1,200

Cost of Goods Sold (FIFO):

Beginning Inventory: 100 units at $8 per unit = $800

Feb. 20: 600 units at $9 per unit

= $5,400

May 5: 500 units at $10 per unit

= $5,000

Aug. 12: 200 units at $11 per unit

= $2,200

Total Cost of Goods Sold (FIFO):

$800 + $5,400 + $5,000 + $2,200

= $13,400

LIFO (Last-In, First-Out):

Ending Inventory (LIFO):

Beginning Inventory: 100 units at $8 per unit = $800

Feb. 20: 400 units at $9 per unit = $3,600

Cost of Goods Sold (LIFO):

May 5: 500 units at $10 per unit

= $5,000

Aug. 12: 400 units at $11 per unit

= $4,400

Dec. 8: 100 units at $12 per unit

= $1,200

Total Cost of Goods Sold (LIFO):

= $5,000 + $4,400 + $1,200

= $10,600

Average-Cost:

Total Cost of Goods Available for Sale: $16,800

Total Units Available for Sale:

Beginning Inventory: 100 units

Feb. 20: 600 units

May 5: 500 units

Aug. 12: 400 units

Dec. 8: 100 units

Total Units Available for Sale:

= 100 + 600 + 500 + 400 + 100

= 1,700 units

Average Unit Cost:

= Total Cost of Goods Available for Sale / Total Units Available for Sale

= $16,800 / 1,700 units

= $9.882 per unit

Ending Inventory:

Remaining Units: 1,700 units - 1,500 units (sold)

= 200 units

Ending Inventory = Remaining Units x Average Unit Cost

= 200 units x $9.882

= $1,976.40

Cost of Goods Sold (Average-Cost):

Total Cost of Goods Available for Sale - Ending Inventory

$16,800 - $1,976.40 ≈ $14,823.60

Therefore, under the average-cost method:

Ending Inventory ≈ $1,976.40

Cost of Goods Sold ≈ $14,823.60

Compare the calculated values with the cost of goods sold formulas.

FIFO Cost of Goods Sold:

Beginning Inventory: 100 units at $8 per unit

= $800

Feb. 20: 600 units at $9 per unit

= $5,400

May 5: 500 units at $10 per unit

= $5,000

Aug. 12: 200 units at $11 per unit

= $2,200

Total Cost of Goods Sold (FIFO):

= $800 + $5,400 + $5,000 + $2,200

= $13,400

LIFO Cost of Goods Sold:

May 5: 500 units at $10 per unit

= $5,000

Aug. 12: 400 units at $11 per unit

= $4,400

Dec. 8: 100 units at $12 per unit

= $1,200

Total Cost of Goods Sold (LIFO):

= $5,000 + $4,400 + $1,200

= $10,600

The match the values obtained using the formulas, proving their accuracy.

To find the total variable cost for 6 jackets, calculate the average variable cost per jacket from the 7 jackets and multiply by 6. Other given economic scenarios involve calculating firm profits, break-even points, and shutdown points based on provided cost structures and market conditions.

The question relates to determining the total variable cost of 6 jackets, based on the given information that 7 jackets have a total variable cost of $300. Without specific details on how the costs change with each additional jacket, a direct calculation is not possible. However, if we assume that the variable cost per jacket is consistent, we can calculate the average variable cost per jacket by dividing the total variable cost for 7 jackets by 7, which is roughly $42.86. We would then multiply this average variable cost by 6 to find the total variable cost for 6 jackets.

For the firm with a total fixed cost of $1,000, a total cost of $4,200, and an output of 500 units, the total variable cost is $3,200. Similarly, for the firm with a total fixed cost of $1,200, a total cost of $4,000, and an output of 1,000 units, the total variable cost is $2,800. This information helps to determine the firm's break-even and shutdown price points.

The new number of chairs produced per month is 7125

To find the amount of decrease:

Calculate 5% of 7500 chairs: 7500 x 0.05 = 375.

The practical domain of the function f(c) = 24c + 7 is the set of positive integers from 1 to 8, inclusive.

The practical domain of a function represents the set of input values for which the function is defined and has a meaningful output. In this case, the number of cases of water Rocky buys, represented by 'c', cannot be negative because you cannot buy a negative number of cases. Additionally, the store has a limited stock of 8 cases, so Rocky cannot buy more than 8 cases. Therefore, the practical domain of the function f(c) = 24c + 7 is the set of positive integers from 1 to 8, inclusive.

The practical domain of the function is the set of integers from B) 1 to 8, inclusive.

The practical domain of the function can be determined by considering the limitations of the problem. In this case, Rocky can only buy a whole number of cases, so the number of cases he buys must be a positive integer.

Additionally, since the store has 8 cases in stock, Rocky cannot buy more than 8 cases. Therefore, the practical domain of the function is the set of integers from 1 to 8, inclusive. Thus, the practical domain of the function f(c) = 24c + 7 is the set of positive integers from 1 to 8, inclusive.

The solution of the given equations is equal to (x,y) = (1,3)

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

Given equations:-

The equation will be solved as:-

2y   =  8 - 2x   (divide by 2 on both sides)

y     =  4 - x      (insert this into the second equation

2  x  (  4  -  x  )  -  4x  =  2

8  -    2x  -   4x     =   2

8   -    6x   =    2

-6x    =    2   -   8

-6x    =   -6

x       =    1      (insert this into either of the first two equations)

2y   +   2 x 1   =    8

2y   +    2     =    8

2y     =     8   -   2

2y    =    6

Answer:

The plane is at an altitude of 3597 feet

Step-by-step explanation:

Airplane is flying at an altitude of 3000 feet.

Now it dives 630 feet, then the altitude is 2370 (3000-630).

Then it rapidly climbs 1048 feet, then the altitude will be 3418 (2370+1048).

Then it again drops 888 feet, meaning now its at at altitude 2530 (3418-88).

Then it again climbs 1067 feet, now the altitude will be 3597 (2530+1067)

Therefore, the plane is at an altitude of 3597 feet. (Assuming that Again 888 feet before making another climb of 1067 feet has been typed twice by mistake. I considered only 1 drop of 888 and climb of 1067)

2x + 7 <= 3x - 5

Treat <= as an = sign unless you divide or multiply by a negative number.

2x + 12 <= 3x

x <= 12

The answer is all real numbers less than or equal to 12.

2x + 7 ≤ 3x - 5

Isolate the x. Subtract 3x and 7 from both sides

2x (-3x) + 7 (-7) ≤ 3x (-3x) - 5 (-7)

2x - 3x ≤ -5 - 7

Combine like terms

(2x - 3x) ≤ (-5 - 7)

-x ≤ -12

Isolate the x. Divide -1 from both sides. Remember that when dividing by a negative number, you must flip the sign.

(-x)/-1 ≤ (-12)/-1

x ≥ -12/-1

x ≥ 12

x ≥ 12 is your answer

Hence, the dot plot will be a horizontal line such that the number are at a increment of 1 starting from 35 and shows up to 50.

This means that there are 1 dots over: 36,37,38,39,40,45,46 and 50.

The correct dot plot is attached to the answer.

Given that admission fee for 1 child = $3.25

If there are x children then admission fee for x children = $3.25x

Given that admission fee for 1 adult = $6.25

If there are y adults then admission fee for y adults = $6.75y

Then total fee collected = 3.25x+6.75y

Given that On a certain day, 870 people enter the fair then equation will be

x+y=870

or y=870-x...(i)

And  $3,772.50 is collected means we get equation:

3.25x+6.75y = 3772.50

or 325x+675y = 377250...(ii)

Hence required system of equation is {x+y=870, 3.25x+6.75y = 3772.50}

Now we solve both to find values of x and y

Plug (i) into (ii)

325x+675(870-x) = 377250

325x+587250-675x = 377250

587250-350x = 377250

-350x = 377250-587250

-350x = -210000

x=600

now plug value of x into (i)

y=870-x=870-600=270

Hence final answer is:

Number of children = 600

Number of adults = 270

For this case we have the following variables:

x: Represents the number of children at the fair

y: Represents the number of adults at the fair

If 870 people enter the fair we have:

[tex]x + y = 870[/tex]

If that day is collected 3772.50 dollars, we have:

[tex]3.25x + 6.75y = 3772.50[/tex]

So, we have two equations with two unknowns:

[tex]x + y = 870[/tex] -----> (1)

[tex]3.25x + 6.75y = 3772.50[/tex] -----> (2)

Clearance of (1):[tex]y = 870-x[/tex]

Substituting in 2:

[tex]3.25x + 6.75 (870-x) = 3772.50\\3.25x + 6.75 * 870-6.75x = 3772.50\\3.25x-6.75x = 3772.50- (6.75 * 870)\\3.25x-6.75x = 3772.50-5872.5\\-3.5x = -2100[/tex]

[tex]x = \frac{-2100}{-3.5}\\x = 600[/tex]

Thus, there were 600 children at the fair.

To know the number of adults, we cleared and from the equation (1):

[tex]y = 870-x\\y = 870-600\\y = 270[/tex]

Thus, there were 270 adults at the fair.

Answer:

Total amount spent on 4.6 pounds of ground beef = $16.33

We have to determine the amount spend on 3 pounds of ground beef.

We will use unitary method to solve this problem.

So, amount spent on 1 pound of ground beef = [tex]$16.33 \div 4.6[/tex]

= $3.55

So, amount earned on 3 pounds of ground beef = [tex]3 \times $3.55[/tex]

= $10.65

Therefore, Lena will spend $10.65 on 3 pounds of ground beef.

So, Option C is the correct answer.

To determine Lena's expense for 3 pounds of ground beef, the cost per pound is calculated as $3.55, resulting in a total cost of $10.65.

To calculate how much Lena will spend for 3 pounds of ground beef, we first need to determine the price per pound that Andy paid. Andy spent $16.33 for 4.6 pounds of ground beef, so we divide the total cost by the number of pounds to find the price per pound:

Price per pound = $16.33 / 4.6 pounds = $3.55 per pound

Lena needs 3 pounds of ground beef, so we multiply the price per pound by the number of pounds Lena needs:

Cost for Lena = $3.55 per pound × 3 pounds = $10.65

Therefore, Lena will spend $10.65 for 3 pounds of ground beef, which corresponds to option C.
