The sum of four positive integers is 125. If you increase the first number by 4, decrease the second by 4, multiply the third by 4, and divide the fourth by 4, you produce four equal numbers. What is the smallest of the original numbers

The value of TV for the similar triangles is 25

Similar triangles are the triangles that have corresponding sides in proportion to each other and corresponding angles equal to each other. Similar triangles look the same but the sizes can be different.

Similar triangles are not the same as congruent triangles though.

triangle UXW and UTV are similar since line TV cuts lines UX and UW in the same proportion.

Let UV = p, it means also that WV = P. which means WU = 2p

so since the two triangles are similar, the ratio of their corresponding lengths are equal

meaning,

UV/UW = TV/XW

substituting their values, we have

p/2p = TV/50

by cross multiplying,

2p x TV = 50p

2TV = 50

TV = 50/2 = 25

In conclusion,  the value of TV is half the value of WX = 25

By using the concept of growth, it can be calculated that

Value of coin in 8 years is $3.52

[tex]3(\frac{51}{50})^x[/tex] is the required exponential function

Domain of the function is all positive real number

Range is [tex](0, \infty)[/tex]

y- intercept is 3

This means initial value of the coin is $3

What is growth?

Growth is the exponential increase in the value of the product at a certain rate over a certain period of time

Here, concept of growth has been used

Present value of the coin = $3

Rate = 2%

Time = 8 years

Future value =

[tex]3(1 + \frac{2}{100})^8\\\\3(1 + \frac{1}{50})^8 \\\\3(\frac{51}{50})^8[/tex]

= $3.52

If the time is x years, the given exponential function is

y =

[tex]3(1 + \frac{1}{50})^x\\\\3(\frac{51}{50})^x[/tex]

This is the required exponential function.

Since x represents time here, then x has to be positive

Domain of the function is all positive real number

Now

As  [tex]x\rightarrow \infty[/tex], [tex]f(x) \rightarrow \infty[/tex]

As  [tex]x\rightarrow -\infty[/tex], [tex]f(x) \rightarrow 0[/tex]

Range is [tex](0, \infty)[/tex]

For y- intercept, x = 0

Putting x = 0, we get y = 3

y- intercept is 3

This means initial value of the coin is $3

Answer:

---------------------------

Answer:

Step-by-step explanation:

1) v + 8w = 4v, for v?

→ v + 8w = 4v

→ 8w = 4v - v

→ 8w = 3v

→ [ v = (8w)/3 ]

Thus, value is (8w)/3.

2) -m + 5n = -2, for n?

→ -m + 5n = -2

→ 5n = -2 + m

→ 5n = m - 2

→ [ n = (m - 2)/5 ]

Thus, value is (m - 2)/5.

The equation of line passing through points (4,−2) and (8, 3) is 4y - 5x + 28 = 0

A straight line can be written in the form of equation as, y = mx + c.

Two straight lines intersect each other only at one point.

When two straight lines are parallel to each other the angle between them is zero.

Given pair of points are  (4,−2) and (8, 3).

The equation of line passing through two points (x₁, y₁) and (x₂, y₂) is given as,

y = ((x - x₁) / (x₁ - x₂)) (y₁ - y₂) + y₁

Substitute the respective values to get the equation of line as,

y = ((x - 4 ) / (4 - 8)) (-2 - 3) + (-2)

y = ((x - 4 ) / 4) × 5 - 2

4(y + 2) = 5(x - 4)

4y - 5x + 28 = 0

Hence, the equation of line for the given points is 4y - 5x + 28 = 0.

Given,

Ellipse given,

x²+ xy + y ² = 7

Differentiating:

dy/dx

x²+ xy + y² = 7

d/dx(x² + xy + y²) = d/dx(7)

2x + 1y + x dy/dx + 2y dy/dx = 0

dy/dx = 2x + y/ x + 2y

dy/dx = 0

2x + y = 0

x + 2y = 0

Now, we have 2 equations,

The number of cupcakes sold will be 4.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that, in the first hour, Brady sold 1/3 cupcakes and Jaquan sold 3/8 cupcakes. During the second hour, they sold 2 cupcakes. During the third hour, they sold 75% of the remaining cupcakes. During the fourth hour, they sold the remaining 3 cupcakes.

The number of cupcakes sold will be,

N = (1/3) + (3/8) +[(2-1/3-3/8)]+3

N = (1/3)+(3/8) + (7/24)

N = 96 / 24

Answer:

12 ft, 13 ft , 17 ft

Step-by-step explanation:

let x be the length of the second side , then

one side is x + 1

third side is x + 5

the perimeter P is the sum of the 3 sides, then

P = x + x + 1 + x + 5 ← collect like terms

P = 3x + 6

given P = 42 , then equating gives

3x + 6 = 42 ( subtract 6 from both sides )

3x = 36 ( divide both sides by 3 )

x = 12

x + 1 = 12 + 1 = 13

x + 5 = 12 + 5 = 17

the 3 sides are 12 ft, 13 ft , 17 ft

The calculation of the ending inventory and the cost of goods sold using FIFO and LIFO methods for ABC Inc. is as follows:

                                          FIFO          LIFO

Ending inventory          $10,250     $12,800

Cost of goods sold       $17,000     $14,450

FIFO, which means First-in, First-out, computes the cost of goods sold based on the assumption that the physical flow of goods sold depends on the earlier inventory in stock.

FIFO can be applied under both the perpetual and periodic inventory systems, unlike LIFO.

LIFO means Last-in, First-out, and as a cost flow assumption assigns the cost of goods sold based on the latest inventory purchases.

LIFO cannot be used under the perpetual inventory system.

Date        Activities                       Units     Unit Rate      Total Cost

April 1     Beginning inventory       220          $50             $11,000

April 10   Purchases                         50          $45                2,250

Units sold                                      320

Ending inventory                         250

FIFO:

Ending Inventory = $10,250 (200 x $40 + 50 x $45)

Cost of goods sold = $17,000 ($27,250 - $10,250)

LIFO:

What is addition and subtraction of integers?

At first it is important to know about integers

Integers are those numbers which has no fractional part. Integer can be positive, negative and zero is also an integer.

Suppose there are many integers, and we need to find the sum total of all those integers, then the operation used in this case is called addition.

To find how big or small one integer is from the other, then the operation used is called subtraction of integers.

Here we will use addition and subtraction of integers

Bank balance of Mohammed = $8376

Amount of money taken out by Mohammed next month to buy a car = $4595

Amount of money needed to buy new tires for his car = $1200

Amount of salary received by Mohammed next day = $2709
